I need to connect my laptop and another computer which runs on Windows . My laptop is currently connect to the internet through wireless ADSL VPN router. I have a LAN cable and a USB to Fast Ethernet Adapter.
This was actually INSANELY easy to do with Windows on the laptop. This tutorial is for sharing on laptop and client on desktop.
:::SETUP FOR SHARING INTERNET:::
On laptop go to control panel, network and internet, network and sharing center...
Once here click "view status" next to your wireless connection..
Under Activities, click properties...
Then click on the second tab "sharing"
Click the first option "Allow other network users to connect through this computer's internet connection"
It should be set up to share internet with whatever device is on the network with the laptop.
Now you just have to network your other pc with the laptop. You might be super lucky and plug in a ethernet cable from your laptop to your desktop and it will find everything and work off the bat... but probably not.
You will probably get the little yellow triangle that says limited connection. If that happens you need to force your computers IP number.
This is pretty easy once you have done it a few times. (if youve been to a lan event of course you know this)
:::FORCE LAN IP:::
just go to Start, connect to, show all connections.
Here you should find a "local area connection"
Right click on it and click properties...
click on Internet protocol (TCP/IP) and then click properties...
c*lick on the second tab Alternate configuration...
Click the radio button User configured...
Then for IP address put in 192.168.0.5
and for Subnet mask put in 255.255.255.0
then click ok...
You have to do this on the other computer as well... its basically the same on vista you just have to click on "view status" of the local connection rather than the wireless and click on properties. Then continue from "click on Internet protocol (TCP/IP) and then click properties..." but make sure you make your ip address to 192.168.0.7.
On the second computer use any other number in the IP address other that what you used on the first one. So if your first desktop is 192.168.0.5, make your laptop 192.168.0.6 or 192.168.0.7 etc, the subnet mask should be the same though.
After you do this on both computers they should reconnect just fine (without the limited connection problem). Then it should work.... if not you will have to refresh your ip. You can do this either by restarting your pc (long way) or by going to command prompt and refreshing your ip. You should only have to do this for your desktop.
go to start, run, and type in cmd and hit ok...
then type ipconfig /release
wait for a second then type...
wait for about a minute and you should be good.
It should refresh with mshome and then 3 numbers below it, after that you should be good and have internet on your desktop through the wireless on the laptop.
I was able to play some online games with friends on my powerhouse desktop on my HDTV last night without having to drag out a 40ft cable to the living room =)
After you are done having fun you should put your ip back to "Automatic private ip address" in the Alternate configuration of the internet protocol settings. (both computers)
If you are getting wifi on your laptop then connect to PC with lan cable, go to network connections and select your wifi and lan connection, then right click and bridge connections. you should be good to go.
If you have more than one computer at home and have only one internet connection, you might be wondering how to use internet in both the computer.
Let's assume there are two computers A and B. Computer A runs on Windows Vista and Computer B runs on Windows XP.
Computer A is connected to Internet via cable, so this will be connected through a LAN card. Now to connect computer B, you will need another LAN card in computer A or if you want to connect to more than one computer, you will need a wired hub.
First let me explain how to connect two computers in LAN.
Step 1: In Vista, before doing this you should enable Sharing and Discovery. You can do that by going to Control Panel -> Network and Sharing Center. Under the section `Sharing and Discovery, enable Network discovery, File Sharing, Public folder sharing and others if you want to. (See picture below)
Here, first network represents connection to internet and second one the local connection with another computer.
Step 2: If your LAN card that is connecting to another computer is installed, it will be shown under Control Panel -> Network Connections.
Step 3: Right click that local area connection and click properties.
Step 4: Under the tab `Networking', click the properties Internet Protocol Version 4 (TCP/IPv4).
Step 5: Click the radio button to `Use the following IP' and give an IP address (For example, IP address: 192.168.0.1 and Subnet Mask: 255.255.255.0)
Step 6: Don't give any other information, Click Ok and close everything.
Step 7: In computer B, make sure you enable the LAN card which is used to connect to computer `A'. Here you need not give any IP information as Computer `A' will assign an IP address dynamically. If it's not working make sure there are no IP assigned and change the properties to `Obtain an IP address automatically'.
Step 8: Test the connection by pinging. (You can do this by typing ping 192.168.0.1 or whichever is Compter `A's IP in the comand prompt)
Sharing the Internet connection of computer `A' with computer `B':
Right click LAN card which is connected to Internet under Control Panel -> Network Connections and click `Sharing' tab and enable both the options to share Internet. (Note: Unless there is another enabled LAN setting you will not be able to see the shared tab under properties)
Click Ok and close. This option is given by the Windows OS known as ICS (Internet Connection Sharing).
Now you can use Internet from both Computer A and Computer B from a single connection.
Note: You can also setup password protected internet sharing, if you insist in privacy. Read more about in the comment by Termino and following comments
To share an internet connection of a laptop that is already connected to a WIFI.
Note that you do not need any IP-addresses here.
connect your laptop to the WIFI provider.
Run the internet connection wizard
At the internet connections options, choose the third option that says "make a home network or connect to a small office network.
click next next next bla bla bla until you reach a window that shows your current WIFI connection do not forget to click or check the box that says "ignore the disabled network equipment"
From the next window, choose the first option. This option configures your Laptop as a server thereby allowing internet connection sharing. click next next next bla bla bla until you are prompted to restart your computer. When your computer is restarting, you will receive a message that a gateway will be created for this connection, answer "YES" and that is all.
As for the second computer, connect it to the Laptop by a twisted pair cable (RJ-45+CAT5 cable).
Switch on the computer and repeat Step 1 to Step 4. In Step 5, choose the second option. this configures the second computer as a client to the Laptop.
click next next next bla bla bla until you are prompted to restart your computer. As soon as the restart is done, you second computer should browse the internet without any clicking. Enjoy !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
