Limited Connectivity With Windows 7

Hello,

Right I'm currently having problems connecting with my newish Windows 7 desktop that's custom built. When I initially received it I had no issues connecting with it to my home wireless connection. Now it constantly gets the Limited Connectivity error Also keep in mind that all other wireless devices that use the same network connect without a problem. I've searched the forums and done Google searches to help resolve this issue but nothing appears to work.

Here's a list of what I've tried (remember at least):

1) Uninstall/Reinstall wireless driver (also made sure it's most current)
2) Change the IP address
3) Do a system restore to a previous date where it [somewhat] worked
4) Power off and on both modem and router for 5 minutes
5) Tried uninstalling/reinstall some hidden drivers (they're back but that idea from another forum didn't work)

There was probably a few other things it's just that I've tried so many different things I've forgot what I all did.

Any help is greatly appreciated!
