Linksys router limited or no connectivity

[Armymech]

I know that many have posted in here about limited or no connectivity in a wireless router before, But i didnt see any thing about my problem.

I have a linksys router connected to my cable modem, the computer i am currently on is connected to the router and works just fine. However i have another computer connected to the same router that consistantly has limited or no connectivity to the web. I use 2 laptops ( for my kids) and they are able to get onto the web no problem.

So im thinking it is something in the computer itself that is keeping it from connecting to the net.

I have tried renewing the ip for the computer. Rebooting the computer. power cycling my router and modem, and changing ports in the router itself of the problem computer.

If any one has any sugestions PLEASE let me know how to fix this problem
