Hello there, so I have a linksys wireless card in my pc, that has been working fine for years, then all the sudden stopped, when I try to use the internet, I get unable to find page. However when I check my signal , it says i'm connected, I have tried to uninstall the hard and sorfware, but could not find the program on my computer, also the original disc will not install, not even when I tried on my roomates computer, whats going on here?
