This adapter worked before but now it won't work now for some reason (I am connecting via broadband now).... When I hover my mouse over to the Ralink UI, it says "Ralink Wireless LAN card does not exist", and it also has a black X over it.. Please help... I even tried doing a system restore, but all I got was the BSOD (Blue Screen of Death).
More aboutralink wireless card exist
sounds like a hardware problem. if the drivers are installed and the ralink still doesnt work you'll want to replace it.
