Wifi connected but can't open any websites [Solved/Closed]

Since Friday morning my HP laptop (has windows 7 home premium) can't open any websites. It shows the internet connected on the network (on IPV4). I have rebooted, restarted modem. released and renewed IPconfig, disabled bonjour, to no avail. Ran multiple diagnostics, one of them said "One or more network protocols are missing."

The other part of the problem is when connected through ethernet directly to modem, laptop tells it is unidentified network, the diagnostic identified error as " local area connection does not have a valid IP configuartion."

Please help.

Can you run command prompt as administrator (click start and search for cmd)

type sfc /scannow and report on the results.

can you also go to control panel > internet options > delete your temp files and then go to the advanced tab and hit reset and restore then apply.

what is the make/model of your PC.

I am suspecting it has something to do with the windows firewall. It is telling me to update firewall settings and when I click the "use recommended settings" tab it is giving a message - windows firewall can't change some of your settings Error code - 0x80070424, may be I am wrong.

Also I can't connect to internet even with Ethernet connection. with this it does not even show internet availability

Kieferschild,

I am using McAfee internet security and after full file scan it did not show any virus. I switched its firewall off. Also I fixed the windows firewall problem but still no internet.

I am running out of ideas, pl. help.

If I may, Windows 7 needs to have a network location. It doesn't always prompt that. Set it to home, work or public.

Try that. Sorry it is too simple to not check!

can you go to the following directory:

C:\Windows\System32\drivers\etc

there is a file called hosts

open it with notepad

it should look like this:



make sure there are no more entries with random numbers and websites.

Can you do another ping to google and when you get the reply IP Address so for example in your last reply (173.194.33.113) - copy this IP and go to internet explorer and go to http://173.194.33.113

see if the webpage is resolved when you go to its IP address.

Sounds like you've managed to screw up some windows configuration. I recommend taking a backup of your data and restoring your laptop back to factory settings.

I did the restore to a point 8 months back. No effect on the browsing. still as it was. I think something linked to DNS that did not get impacted by restore, puzzled to say the least.

I would suggest you to follow the steps mentioned below.



Step 1: Disable the IP Helper service
a. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
b. Scroll down to the IP Helper service, right click on it and select Properties
c. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
d. Then click on "Stop" to stop the service from running in the current session
e. Click OK to exit the dialog

Step 2: Disable IPv6
Try uninstalling IPv6 on all interfaces, removing any IPv6 virtual adapters, and resetting the TCP/IP stack. To remove IPv6, go into the properties for each network adapter and either uncheck the box next to the protocol "Internet Protocol version 6 (TCP/IPv6), that will disable it, or select it and click uninstall, which will remove it off the computer. Then go into device manager and remove any 4to6 adapters, WUN miniport adapters, or tunnel adapters.
NOTE: You should do this for each network connection.

Step 3: Disable the DHCP Broadcast Flag
Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Back up the registry
http://windows.microsoft.com/en-US/windows7/Back-up-the-registry


Windows 7 cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers
To resolve this issue, disable the DHCP BROADCAST flag. To do this, follow these steps:
a. Click Start, type "regedit" in the Start Search box and then click "regedit" in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
b. Locate and then click the following registry subkey:
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}"
c. In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
d. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
e In the New Value #1 box, type "DhcpConnEnableBcastFlagToggle" and then press ENTER.
f. Right-click "DhcpConnEnableBcastFlagToggle" and then click Modify.
g. In the Value data box, type 1 and then click OK.
h. Close Registry Editor.
By setting this registry key to 1, Windows 7 will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.

I suggest you contact you ISP. They should be able to run a diagnostic check on the modem.

Good Luck

the sfc /scannow gives this message "Windows resource protection did not find any integrity violations."

1. Driver installation test
2. Card insertion test
3. Card enable test
4. Association test
5. Authentication test
6. network test

Adapter is Atheros AR9285 802.11b/g/n wifi adapter

laptop is windows 7 HP G62 notebook pc AMD Phenom (tm) II N850 Triple core processor 2.20 GHz 4 GB 64 bit operating system.

I also ran cmd (admin) Netsh int ip reset resetlog.txt and reboot to no effect

Can you go to start > type "services" and open that up.

locate Windows Firewall and ensure that its startup is set to automatic and that it is started then try using recommended settings.

what antivirus software do you use?

ac3mark,

thanks for the suggestion, but it is set to home always. You are right though, I feel it is possibly something simple.

kieferschild,

The windows firewall seems to be working fine now. It is not prohibiting any websites. I am away from my laptop currently but I will check the link later. thanks.

Kieferschild,

appreciate your advice.

C:\Windows\System32\drivers\etc gives exactly the same results as you showed. google ping resulted in 173.194.33.115, I tried this but webpage is still not resolved.

okay so you cannot get to http://173.194.33.155 ?

Are you using internet explorer?

Do you have another computer you can download mozilla firefox or google chrome from?

Try another web browser and see if you can get on.

I would also like you go to go Start > Control Panel > Internet Options

go to the far right "advanced" tab and click reset and restore advanced settings then apply.

Kieferschild,

thanks. did all that. I already have mozilla firefox which was not letting me do anything also.

Today when I used http://173.194.33.115 for google in Mozilla that actually took me to google and allowed me the search but the thread I clicked for Microsoft did not go anywhere.

This is first time I saw any website in a week. small progress.

I immediately tried pinging Microsoft.com and use the result in Mozilla but that did not work.

by the way, earlier I also uninstalled and installed the wifi driver, no difference
