Modem is connected but not the internet? Solved

Question

Hello,

I am sharing a wireless modem connection with my neighbour (long story - he has the modem and has loaned the secured access key to me) and he only just gave me the access key today. I initially had issues with connecting the modem (ie was recieving "Limited or no connectivity" messages even though I had a strong signal) until I figured out how to connect it [ie by changing the Internet Protocol (TCP/IP) settings; User Configured to IP address:192.168.0.2; Subnet mask: 255.255.255.0]. 

However, this has not solved the problem of connecting me to the internet! When I attempt to use ie7 to browse, I still get the error "Internet Explorer cannot display web page" even though the moden is definitely connected (55 packets sent, 0 recieved so far). Here are some things that I have done so far:

- In ie7, I made sure that under "Internet Options" , the "Never dial a connection" radio button is selected. 
- In ie7, I have also ensured that under LAN settings, the "Automatically detect settings" tickbox is the only box ticked.
- In the Command Prompt, I ran a "ping" (ie ping 4.2.2.2) and the stats show no lost packets with an average round trip of 553milli-seconds. I guess this means that I do have a connection to a network (right?)
- In the Command Prompt, I also ran "ipconfig" which confirmed that my "Ethernet adapter Wireless Network Connection" = Autoconfiguration IP address:192.168.0.2; Subnet mask: 255.255.255.0

Still no internet and I am outta ideas!!!

Can anyone suggest what I need to do to make my internet connection work??

Check and see if you have an IP Address confliction within the network.  In other words 2 computers with the same IP addresses.   If you do, just change the last number of the string.  

Here's how:

Go to Settings (where the Start is at bottom left) and select Network Connections.  
Find Wireless Network Connection.  Right mouse click on it and go to Properties.   
Highlight on the Internet Protocol (TCP/IP) and click on Properties.  
At IP address: , change the last digit of the IP address.  Chose a higher number.  Chances are the lower numbers are all taken. Click Ok and exit out of all the settings.

Now try to open your internet browser again.  

Hope that helps.

your neighbour's router might be configured to issue out only one IP address so even if you have the key, if neighbours pc is on then you will not be able to obtain an IP address and therefore browse

TJ · Answer

To answer your question, have your neighbor do the following,
(Don't type the quotes just the command inside)
Click on start, then run
Type 'cmd'
hit enter

type ipconfig/all
hit enter

You need to have a different IP address than he has, so if his is 192.168.1.11, pick the last number and add 100 to it to be safe, so yours would be 192.168.1.111 (just an example)

Your netmask will be the same as his, 255.255.255.0
your gateway will be the same as his 

You also need to have the DNS servers that are listed, there should be 2 of them, write both of them down.

So, on your sheet of paper, you will have a unique IP address, the same netmask and gateway, and 2 dns servers.

Go to your PC, start, control panel, network connections, right click on Wireless Network Connection, then select properties,  On the general tab screen, Select Internet Protocol (TCP/IP), and click properties,

Then enter your unique IP address, netmask, gateway, and both dns servers.  Click ok, then ok again.  

Then on your notebook/pc, click on start, run, type cmd, hit enter
type 'ipconfig/all' 
hit enter, your info should match your neighbors except for the IP address
type 'ipconfig/flushdns'
hit enter
type 'exit'

now try to get online with internet explorer, you should be successful, if your not, post back on here with your results and I'll get back to you.

I'll will be very interested in the answer to Jules as I have a similar problem. At home, I have the router connected to my PC and my daughter has a laptop with wireless. All this worked fine before she left for the summer. Now that she is back, her laptop sees the internet wireless connection but does not connect to the Internet. Now two weeks later, I moved my PC to another room and the same thing is happening to it. Connection is there but can't access the Web. I know that the adapter is working properly as I use it on my work laptop and everything is fine. Got any ideas for me too?

Thanks

I seem to have lost TJ. Is there anyone else that can offer some advice to my problem? 

Many thanks in advance.

tjmartineau · Answer

Gab, you didn't lose me, I got caught up with way too much other things...my apologies.

On your desktop PC, you either have one of three things, a bad cable, a bad network card (Built in most likely), or my suspicion is a bad port on your router.

On your laptop, if it cannot receive an ip, which we all realize via the router's DHCP server, it should, I'm also suspecting your router.  

Do you happen to have a spare around? Wired or wireless, it doesn't matter right now, we just need to see for sure that you can hook up a different router, and get an IP from both your desktop, and laptop. You may be able to search Craigslist and get one really cheap, else try a big box retailer to get one cheap and quick for probably around $25 or so, you don't need anything fancy like "Wireless N" or any of that, you just need a basic wireless router.

With that being said, what type of router do you have, you could try factory resetting the router, plug the PC into a different port, with a different cable, and see if it works.  Get me the make/model and I'll talk you through it.

Gab2001 · Answer

Thank you TJ. Sorry, I did not mean to be impatient and no need to apologise. Of course, I understand that you have other things that need looking into. 

My work laptop, thanks to which I am still connected to the Internet, uses my D-Link wireless adapter and my router (a D-Link too) so I know all that is working fine, which is why I am sort of baffled by all this.

tjmartineau · Answer

You need to get onto the D-link router's configuration page....see if by chance there is a limitation with the number of DHCP clients that are able to connect.  I sometimes only set that number to 1 or 2 depending on the client's connections so that way any other connections are rejected.  Set it to a range of 10 or so if it's not.

Also while you are in there, there should be a status page, or a page that states something like, DHCP Client's list.  Click on that, and see if there are any connections other than your work laptop.  If all is like you state, there should only be one DHCP connection, your laptop.  If there are any other connections, your security may have been breached if you have it enabled, if you don't, you'll need to enable some sort of security because your neighbors may be pulling off your network.

Look onto the back of your PC for a second, where your ethernet cable plugs in, do you have a green link light back there (a tiny green square should be lit right above the cables connector).  If that is not lit, the adapter or the cable, or the port on your dlink is bad. First, try a different port on the dlink, if it lights up...good...if not...it's the cable or nic.

Let me know if you see anything odd in the dhcp client listing....I sure hope so....if not, and you do have a link light on your pc, we're going to have to factory reset the router and reconfigure it to see if that helps you.  I'm heading to bed so I may not reply until morning...(I'm in Omaha, Nebraska, Central Time)

Good Luck and keep me posted...

Gab2001 · Answer

Thank you TJ. Where can I see the router's config page? Is it possible from my work laptop or should I reconnect my PC directly to the router as it was before I moved it? I looked for it on this laptop but to no avail, maybe because I am connected with an adapter. Would it work if I try to connect my daughter's laptop directly to the router? I'll fill you in on the results later this evening. 

Have a great day,

Hello again TJ

Hope you had a great day. Well I did connect my daughter's laptop directly to the router and everything is working fine. Now my problem is locating the config page of the router. Still searching around for that but not sure what I am looking for. Also should I be setting up a home network? Would that help? Just wondering. 

Take care and I'll look forward to hearing back from you.

tjmartineau · Answer

To get to the config page...

Take your laptop and connect directly to your router.

Click start
then run
type 'cmd' then hit enter

type ipconfig
hit enter

the gateway ip address should be the modem's ip address.  (Like 192.168.1.1 or something...)

Open up internet explorer, in the address bar, type that address, hit enter

Login - username is admin password should just be blank

The home networking thing....that's what we're going to accomplish here...

Hello TJ

I did try to get to the config page. I got the box in which I entered admin and left the password blank but it's not giving me access.

Thank you again for the follow-up. Much appreciated.

tjmartineau · Answer

If the username and password aren't working, is it possible that someone got on your router and locked it?  (Neighbor or other???)  That's D-Link's default configuration, so unless you changed it, you may be better off resetting it and reconfiguring it from scratch.  (There is a tiny red button on the back of the router, hold it in with a paperclip or a pen tip, count to 10, and let go.  Wait a minute, and reconnect, then login.

gab2001 · Answer

I don't believe anyone else got onto my router but I can certainly try to reconfigure it. I have not done it myself before. Is there anything in particular I should know about the process or should be aware of? I know I have to secure it and put in a password for access. Otherwise, is it easy enough for me to do it properly?

Thanks again.

tjmartineau · Answer

Did you reset the password when you first installed it?  If so, find your documents and see if you wrote it down.  Reconfiguring it after factory resetting it is simple, it may even have a wizard if my memory serves me correctly.  

Try it and if that still doesn't work, send me a personal message and we're going to get together virtually and fix this.

tjmartineau · Answer

hello TJ, more info on what I have found. I found the DHCP page. Server is enabled. Static DHCP is disabled.Dynamic DHCP client list shows only the laptop. Does that help?

Yes, it helps.  your server is enabled, so it should be giving out IP addresses to devices connected either physically, or wirelessly to the router.  That being said, your connected wirelessly with your work laptop, and you want to be connected wired via your PC and wirelessly via your daughter's laptop correct...

Start with your daughters laptop, turn off the wireless,  connect an ethernet cable to the proper port on the laptop, and the other end on the router, see if it get's an IP address and can get online.  If it does, you should see it as a client in the status page of the router, if it does not, the ports on the router are bad, or the DHCP server is corrupt and that is your issue.  Do the same thing with your PC.  If it doesn't work the first time, change ports, change cables too if need be.

If it is saying media disconnected on the PC still, even when plugged in, look to see if there is a "Link Light" on the port of the router that the PC is plugged into, if not, change ports, if that still doesn't fix it, and the cable has been swapped with one that you know works, your router has bad ports...

Try that and get back to me with results....we'll work on the wireless after we can establish that the DHCP server is working as it should.

gab2001 · Answer

Thanks TJ. Ok, for starters, and I should have been clearer on this, my daughter's laptop has been connected directly to the router via an Ethernet cable all week and it is working perfectly. media is connected and on the router status page, I see the laptop. 

The adapter I used on my work laptop, I put on my PC to see if whatever we did with the router would allow it to connect wirelessly, which is what I want to achieve. Before I moved it to the other room, my PC was connected directly to the router.

So I guess that confirms that it's working fine. Is that what you were looking for? GAB

gab2001 · Answer

Me again. As another test, I took the adapter back to my work laptop, got on the Internet and came back to my daughter's laptop (which is connected via cable) to check the status page of the router and I see both laptops now.

shaun99900 · Answer

hi, i'm havin trouble with my internet. I have a wireless netgear modem connected to my pc, and I have been using it to connect wirelessly to my laptop for the past 6 months. to connect to it I just click the icon on the bottom right of my screen, on the menu bar next to volume and battery power. well I used to click that and then it showed the wireless networks nearby and my netgear used to be there. but now it just says "windows cant find any networks" so when I click diagnose why windows cant find any networks it then says "this computer does not have a wireless network adapter installed and configured. So I don't know what that means and when I click on the "install wireless networking hardware, and verify that the correct drivers are loaded" it just comes up with the troubleshoot thing which I have looked through all over and theres nothing about installin a wireless network adapter (which also doesn't help as I don't know what one of those is) the 3 links on the troubleshoot are "I just installed a new hardware device, and it is not working correctly" , " my device used to work, but now it doesn't" and "I can't connect to the internet to update my drivers" so I dunno which one is most helpful anyway but iv looked on all of them and tried doing stuff with them but nothing has helped. Does anyone know what the problem is? If you do could you please tell me a step guide to workin out why it's not showing my netgear in the wireless networks and says there isn't any when I have my netgear on and is workin fine. thanks

Marvin · Answer

Hello everyone. My problem is very similar to the postings above. My friend's Vista laptop cannot connect online, but I can tell that it sends and receives packets. It's annoying that I couldn't connect to my router's home page through the default ip address. My router is a Linksys wrt54g.

I've tried the usual steps: ping from the command prompt, repaired connections (both wired and wireless), reset WinSock settings, reset IPv4 and IPv6 stacks and the like, all of which completed succesfully. I know that my modem and router are working fine because my own computers can go online without a hitch. 

I tried System Restore and for some reason, Firefox worked after the restore, but not IE7. Since I wanted to find out the real cause of the connectivity , I un-did the System Restore, so now I'm back at square one.

Some other forum suggested that it might have something to do with a particular update for IE7 (KB947864). I checked it and sure enough, it was on the laptop.  I uninstalled it but still no joy.

I also believe that this is caused by a malware, as my friend told me that he downloaded and tried to install some game before the issues started.

Hopefully we can find a fix soon, otherwise I would just have to wipe out the hard drive and do a reinstall.

Jesta · Answer

Hi, your problem is most likely that you specified the IP yourseld, you should never do that (unless you have a very good reason to) as routers use DHCP, which automatically provides you with an IP address, most routers are set to 192.168.1.1, so the next computer to connect either via wireless or wired would have IP 192.168.1.2 assigned to it. 

Most routers have whats called a DHCP Lease, that means that the IP address assigned to a computer will be the same one for a set period of time, for example: 

Our example router is set to have a DHCP Lease time of 24hrs, and its self assigned IP is 192.168.1.1 

If PC1 (IP Not assigned but TCP/IP setting set to "Obtain an IP address automatically" (Default setting unless youve tampered, ahem!)) connects to the router (192.168.1.1 by default) then the DHCP server built into the router will assign PC1 an IP of 192.168.1.2 

Now Laptop1 (IP set as 192.168.1.2 by user)  connects to the router, the router has already assigned 192.168.1.2 to PC1 and so refuses the connection to be made to Laptop1.  

If PC1 doesnt connect again for 24Hrs (our DHCP Lease time) then the IP 192.168.1.2 will be available. 

You will need to speak to your neighbour to see if he/she/it/they have set the router to limit the IP address's that are available. 

For example... 

My own personal network, the router is (by default and not changable) 192.168.1.1, the maximum connections allowed to a network prefix (192.168.1.XXX) is 254, so with the router set as 192.168.1.1 that leaves me with 253 available IP address's. Now, Im not a school/college/business, so I have no need for 253 address's.  

On a wireless network your router is broadcast, meaning anyone within range of the router can pick up the signal and connect to that router, but thats where encryptions/passcodes or whatever you wanna call it come in. They allow people to see your connection, but not access it without the key/code. You can hide your routers wireless connection, the router and network will both work fine, however you will need to know what your connecting to. Anyway moving on as from what I can tell youve got it set to broadcasting with encryptions so thats fine. However you must check what protocol the router is using (most likely WEP or WPA) as again, that will stop you connecting. 

On my network I have 5 devices that need an IP... 

The Router, 
My computer, 
My Xbox360, 
My girlfriends Laptop, 
Friends Laptop, 

My computer and xbox360 are both wired to the router (it wouldnt be practical to sit on the sofa or bed with my pc or xbox360) 

So I have the five devices that need internet, I now need 5 IP address's, while all of them are able to get one, and the wireless is encrypted (Encryption is WPA-PSK) I dont want anyone to be able to hack my network (although I do somewhat doubt the likely hood of anybody on my street being capable of hacking) so Ive set the router to have a maximum of 5 IP address's, which are... 

Router - 192.168.1.1 
Xbox360 - 192.168.1.2 
My Computer - 192.168.1.3 
Girlfriends Laptop - 192.168.1.4 
Friends Laptop - 192.168.1.5 

The setting is called DHCP IP Address Range, with start and end boxes that I can put IP address into, so my router is 192.168.1.1 so Ill want my start IP address to be 192.168.1.1 and Ill want my end IP address to be 192.168.1.5 because that then allows all the devices I want to connect to have their own IP address. Which they do.  

Because Ive also setup my router to have static IP address's with those devices it means that the xbox360 will always automatically be assigned 192.168.1.2 by the router, no settings have been applied to the TCP/IP settings of the connecting devices because they dont need to know as the router is the decider or what IP address they recieve, so the devices are set to obtain an IP address automatically, which is the default setting on all computers. Its like if I lock my house (my house being the router and me being the DHCP server) and someone comes to my house (a device) only if I (the dhcp server) unlocks the door, can they come in, with having the IP address's set to static its like having all my friends (aka devices) sat/stood in all the windows and doors of my house, so the person I dont want to come in (such as a hacker) has to get past them, which would be exceedling difficult. 

The reason for which is because of whats called a MAC code, this is an address/name or however you like to term it for that device, the MAC code isnt assigned by the router, its one thats assigned and permanent on the computers network adapter, and as your router is a network adapter, yes you guess it, its got one too! So our DHCP Servers name is Adam, Adam has been working at the Router Nightclub since its first day of operation, hes the 24/7 Door Man, and our computers name is Ben, Ben is a Highly Sophisticated Clubber, Ben has a very distinct face because its made up of a long string of numbers and letters that he randomly selected and tattooed on his face (Ben is a very tough sophisticated person, dont you agree?) 

Adam knows Ben because of his distinct face, and the Club Manager has told Adam to always let Ben in, no matter what time he comes around.  

Thats how MAC's work, routers work and how DHCP Servers work and Static Ip's work. You should be suffering from eye strain, aswell as on your way to configuring and setting up your neighbours network, or your own whoever you are whose reading this with a similar problem. 

Jesta 




This is whats happening to your connection and why you cant connect. Simply go back to your TCP/IP settings, I dont know what version of windows your using but you managed to do it once so Im sure youll manage again. If you need help with it, google or email me at Email Id removed for security  and Ill walk you through it with some pictures.

RichHikins · Answer

Hi all and TJ who seems to be the man! 

I am a techy but haven't worked on xp for sometime, I am at a friends for a few days and they have a strange problem... need your help! 

They have an Orange Broadband connection connecting through a livebox.

1 PC
2 XBOX

attached no problem... 

But the main PC they use has suddenly stopped connecting.. when I first looked they had limited or no connectivity, I have solved that and attached them to the router, but using IE7 it doesn't display any web pages...

I have pinged the router and checked all setting in network are the same as other pc... 

I have got onto web pages using the IP address no problem so we defiantly have internet connection but it can't resolve actual domain names...

So from memory it's a winsock or DNS...

I have used the netsh winsock reset to restore original winsock settings but that hasn't solved the problem... 

Any other suggestions would be greatly appreciated...

Kind regards
Rich

k123 · Answer

Hi All

well I finally figured out the problem, turned out there was nothing wrong with the modem, or the router, or the IP address, I just had the password wrong!

my landlord didnt realise that his password had been changed a while back and thats what was causing the problem, even though the failed connection kept saying it was the IP address thing.

someone has put a post on here about changing the last digit of the IP address, so I asked my landlord to look up his IP address with his provider and thats how we realised the problem.

maybe some of you guys have the wrong password too?

Fixed this problem on my d-link router by changing the Primary DNS Address on the Router Internet Manual Connection Settings to 0.0.0.0.

DR · Answer

Hi guys
I've been reading this post but, as a computer novice, I've got really confused. 
I am having a problem that my ISP (Virgin Media) cannot resolve.
I have a Buffalo Air Stream router with a desktop and laptop connected. On the desktop I have an icon stating that there is limited or no connectivity so I am unable to connect to the internet. I did manage to to connect via IP number address when in safe mode and the cable modem connected directly to the PC but not when connected via the router. The lap top shows it's connected wirelessly but cannot display any internet pages.
My ISP said I had an issue of not refreshing DNS server and not taking URS form (their words). 
Has any one got any ideas? Please accept my apologies if I have posted this in the wrong place.

have similar problem m not sure if this can help. I have a desktop but I am connected to wireless modem for some reason every I am turning off my computer I am losing my IP address and everytime that I connect to the wireless modem it gives me a limited or no connectivity. By d way my service is DSL ATT so... What d Att agent did was we connect d Ethernet n reset the set up of the modem he told me sometimes when ur computer crushed or got frozen n u didn't turn it off properly d password 2 ur wireless won't work n will not connect u 2 Internet or modem. When we connect d eternet cable I typed in on d address 192.168.1.254 then when ATT logo shows I clk on home network tab n hit edit setting n I disabled d connection by unchecking it n save n reenable again n save. Everytime u have changes u have 2 change d network n password all d time n save. Then I take d cble out n try 2 reopen back d Internet explr n it worked. Pls make a note of d password  cuz that's d same password that ur going use f u have more than 1 computer @ hom. M not good on giving instructions m hoping that this can help! :)

dnsdnsdnsdnsdns · Answer

I have the same problem. It happened last night after midnight.
I was using skype, msn and firefox at the same time. First I lost firefox but msn and skype was working succesfully.
Then I tried logging off and on and I lost msn. but skype is still working. masn troubleshooter says this is a dns problem.
I cannot surf with browsers by using http https ftp or any kind of protocol with domain names.
However, I can use the ip addresses. No problem in that. So this must be a dns problem.

I tried 

disabling enabling network connections
repairing them
using netsh or ipconfig to reset/flush/register dns 
manually deleting netsock and netsock2 keys from the registry and reinstall tcp/ipprotocol with a new connection
disabling the network card and enable it
uninstalling zone alarm and removing the remaining keys from registry
using a winxpnetsock fix (I am not sure if the name of the fix is correct, by the way I have Win XP SP2)

Surprisingly, I can access to dns servers. I am sure of that. also nslookup works. but browsers do not.
any clues???

Chowdah · Answer

Hello, 
so I recently had trouble with my laptop finding my wireless router signal, and now that I finally got it working, I have stumbled across a brand new problem. It seems that now that I got my wireless working, the router would randomly kick me off the internet, my girlfriend never had a problem with this before. since it's her router, and it only started happening when I finally got my HP laptop on the network (she only has mac computers) I can't help but feel that I had sumthing to do with it. Anyways, so everytime I connect to the internet, I can stay on it for anywhere from 20 minutes to 2 hours or so, but eventually the internet would kick us off where the browser on mine(Windows Vista) and her(macbook) would stop workin 

I would then check the status of my internet, and it would say the signal is still excellent, and whatever I was downloading (ie. Bittorrent) would still be downloadin and uploading at an excellent rate...but the internet would stop working, and eventually I would get kick off of messenger. 


So what I have discovered is that to get my internet working, I have to hard reset the router, and that'll instantly connect me back up to the internet, but kick me off again in 20 minutes, OR I can log onto the NEC Router website and refresh my router, and that'll make it work for an hour or so. 

i just find it kind of weird becaues none of my internet'll connect to any websites, but when I goto my network option and pick aterm and log into website, it lets me get onto the router site...so...with that said..any idea why I keep getting booted out of my internet? please any help would be appreciated.. 

the thing is i'm still fully connected to the internet when the internet goes...the only thing is my browser stops working, everything else is still going...no browsers works on neither computers when this goes, but besides that, everything else works...pleasde help

Shannon · Answer

Having a slightly similiar, yet totally different issue -

My wireless is obviously connected - it says "connection - excellent" but it won't open my homepage. However, when I type in Google, it loads just fine. And when I search for something in Google, that loads just fine, too. However... that's all it does. It refuses to go to any other website, and I can't go to them through the results in google.... It says website found, but it just won't connect. The other laptop in the house works just fine, and this particular laptop works fine when it's connected to the router.... 

So why does Google work all fine and dandy, but everything else doesn;t cooperate?

Must be getting sick of these but im having a problem with setting up. 
pc is connected to modem + router (phillips snb5600) on xp. 
laptop is picking up signal and connecting on vista but it says dns server error. 
the ips are different on each by one digit. 
should the dns number be the same on both? that is what I have anyway. 
my router settings pick up the wireless network name and its ip address. 
everything seems fine besides the dns. 
ive tried some of the steps previously mentioned. 
TJ please help, you seem to be the only one on the whole internet who can help :)

Q · Answer

HI everyone,

Just adding my input. Have a router issued by our local telephone service (telkom - South Africa). Enabling MAC list and many other solutions offered here were helpful in the scenario of my current laptop able to connect wirelessly and via ethernet no problems but bringing home a new laptop would connect hardware wise but would not allow internet explorer access the internet. I simply did the ipconfig /all thing and looked at the DNS setting and on my new laptop inputted that DNS number and presto!!! Maybe that will help others. I am pretty sure I may need to do this at a new site with either cable or wireless. Thanx for lstening Q

We had a storm last night and our internet went down. Normally, it comes back by morning, but this time it did not. I found that if I plug the modem directly into teh computer, the internet works, but if I go modem > router > computer I get "limited or no connectivity" and cannot access any websites. I'm not sure what to do to fix this, I have tried resetting everything in every order I could think of. Please help.

I had the same problem. My internet stopped working after re-installing Norton (NIS). Solution is to install the wireless driver after installing(or re-installing) the anti virus program.

Stigs Uncle · Answer

I have just had the experience of having conection but no internet when I open a browser.

I am lucky enough to have more than one pc and access to more than one wireless router, (I know my neighbour / friend's password!), so I knew that the problem was unique to the one pc.

I had recently removed Norton Antivirus and had found that the internet connection became intermitant as far as the browser was concerned. After a few Windows Updates the connection ceased altogether, even though the pc indicated an excellent conection.

The solution for me was to download the 'Norton Removal Tool' and then run it... once this has finished make sure to restart your pc. Norton sometimes leaves bits behind that can still effect your PC!

I had already tried shutting off firewalls, (On Vista: Start / Control Panel / Security / Windows Firewall) and setting automatic IP addreses, (Start / Network / Network and Sharing Center / Manage Network Connections / then right click on your wireless conection and select Properties, click Continue then highlight 'Internet Protocol Version 6' and click Properties, make sure it is set to Obtain an IPv6 Address Automatically.... do the same for 'Internet Protocol Version 4'. (It is normal that these need to be set to automatic for most wireless routers as the router sets addresses.)

Before I completely lost conection I had tried to download AVG, Spybot and Lavasoft's Adaware; whetever was left behind on my PC prevented me from downloading AVG 9 and Spybot, but I could download Adaware and AVG 8.5, though I couldn't download any updates. Whatever was left behind on my PC from Norton behaved like a firewall that prevented programs accessing the internet.

Hope this is of some help to someone :)

I could not connect at home but only at work. Internet was connected to home wireless lan but no data packets being sent or received.  Then changed the IP adress in the TCP/IP settings in advanced network connections, flicked the qos packet delivery tick on and off a few times while trying to open home page on browser, then reset settings to pick up IP adress autmatically and miracously something released and it works fine.

Apyn · Answer

To anyone that can help, please! :)
I seem to be having the same problem, as well - and I have tried practically every solution on every message board on google to try to solve it. (However, I am in no way "computer-savvy", so although I have been researching quite well, I still don't know the significance of many of the things I have tried...) -OS: Windows Vista Home Premium; wireless network; router - linksys

Computer says I'm connected, but there's no Internet. The rest of the computers with Internet on wireless networks in the home work the perfectly fine. General failure in pinging local host, default gateway, remote host... Tried the ipconfig/release and /renew commands, but it says that the computer cannot contact the DHCP server. Flushed the cache, reset TCP/IP, reset Winsock catalog... etc, etc. Both IP address and DNS Serves are already set to automatically configure. The only thing I haven't tried is completely reinstalling the OS and uninstalling Norton 360, and I'm not completely sure that I want to resort to those options just yet.

A tiny history:
Computer was extremely slow about 1-2 days ago, then after uninstalling Norton Internet Security, everything would stop responding after a pop-up stating how the computer wasn't protected. Before then, Internet was working perfectly. After uninstallment, Internet stopped working. System restore brought Norton back and normal speed, except the Internet doesn't work.

Ipconfig/all more or less provides me with this information:

Window IP Configuration
Host Name - (My name)-PC
Primary DNC Suffix: ?
Node Type: Hybrid
IP Routing Enabled: No
WINS Proxy Enabled: No

Wireless LAN adapter Wireless Network Connection:
Connection-specific DNS Suffix: ?
Description: Intel<R> PRO/Wireless 3945ABC Network Connection
Physical Address: (etc)
DHCP Enabled; Yes
Autoconfiguration Enabled: Yes
Link-local Ipv6 Address: fe80::f452:6ecb:eaee:75de%11(Preferred)
Autoconfiguration Ipv4 Address: 169.254.x.x(Preferred)
Subnet Mask: 255.255.0.0
Default Gateway: ?
DNC Servers: fec0:0:0:ffff::1%1
fec:0:0:0:ffff:2%1
fec:0:0:0:ffff:3%1
NetBIOS over Tcpip: Enabled


Could someone translate this for me? I understand some of it through googling and lurking on message boards and all that, but I still can't quite process the whole thing.

It would be greatly, greatly appreciated if someone could explain why my computer is acting this way - or if not, provide me with some good definitions on all these technological terms... ;)

Happy Holidays!

foty · Answer

I have combed this thread but cannot find the answer to my problem.  I have a laptop docked into a docking station and with a wire, but also wireless is enabled.  The computer will start up, it can handle email via a POP3 client and it can do Yahoo Messenger, but it will not let out http (browsers don't work - IE/FF - neither does Thunderbird email).  If I disable the ethernet card and let the wireless take over, I'm golden, everything works.  What the heck?

I can't see any IP address conflict in my ipconfig, all boxes are selected properly that you all have mentioned - the card can't be failing if it lets out my POP3 transactions and whatever Yahoo messenger is.  I tried a system restore back prior to Saturday morning when this began but it did not help.  If it means anything - when I got up Saturday morning there was no internet connection and so I had to cycle my router.  After that, this problem began.

This happened once before when I tried to install a new router - when I gave up and fell back to the old one, the ethernet card was upset for a few days and then it was ok again.  I can operate wireless happily, but this just bugs me because it makes no sense!
