Hello, I explained my problem:

XP until it had ceased to operate internet and decided to throw it fast and formatting. Install Windows Vista in Vista if I recognized the router and my internet works. However, I have XP, so today I took over the space on the disc and I made another partition. I installed XP on the other. Now I have two problems, still does not work in XP internet, so it seems I do not recognize the router is connected (when in Vista if And one that every time I go into an OS or another I have to insert the installation disc and give it "fix." No list appears when you turn on your PC.
