This card froze my computer when I tried to remove it, when the system went into hibernation mode, and when I tried to shut down. I installed the newest driver available. I could not install the firmware from Linksys's website, as that froze my computer.Linksys's support came to the conclusion that the PCMCIA slots in my notebook are bad (both of them). Toshiba blames Linksys for the problem.The final analysis: Don't buy this card for a Toshiba laptop! If you don't believe me look at Toshiba's online service forum and do a search for WPC11. Many people have had the same problem. Linksys and Toshiba products don't work well together.
