Vista connection problem. Please help!

I'm a mac user. I used PCs for ten years and went Mac last year. I'm glad I did and I won't go back.

However, my roommate recently bought a PC, as she won't switch to a Mac. We're having connection problems. I've got a wireless router set up with my DSL and it connects to my Mac perfectly. The new Vista notebook detects the notebook wirelessly and when plugged in directly to it, and the status is usually 4 or 5 bars, but IE says the page cannot be displayed and that something is wrong with the connection. I've googled similar issues but nothing seems to have worked.

Please help me if possible.

 

Please supply the following info.

The name of your ISP and country of residence.
Make/model of the broadband modem. If dial-up, please specify.
Make/model of the router (if any).
Connection type, wired, wireless.
Make/model of network card or wireless adapter.
Make/model of your computer (motherboard if home-built).


I'd like to see this from the Vista machine.

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
