I have a laptop connect wireless and also have a desk top. I have is the laptop works fine however the desktop won't connect to internet. Was saying no ip address then I did the ipconfig /release and ipconfig /renew and it gave me a ip address but still won't connect to the internet. Don't know how to fix this problem.

How are you connecting to the internet ?
Are you using a router or Internet Connection Sharing?
What operating system on both ?
What IP addresses are you getting on each?

The more information you give us the better we can help to resolve your issue.

I have a lynx wireless router, both computers use windows xp
Laptop and desktop both show 192.168.1.100

Well there's your problem.
Each connected device needs to have a DIFFERENT IP address.
The easiest way to do this is to make sure the router has DHCP enabled and the computer are set to automatically acquire IP addresses.

I got it now thanks
