I have a lifebook B-6230. I need to replace the built in wireless adapter with a new one. When I install the new card, it installs properly and the drivers install. I cannot join any networks, and if I diagnose the issue it tells me the card is off. I know there is a physical switch on the back of the machine, but even with it in the on posistion it still tells me it is off. Is there any way to get around this issue? I have tried it with both windows vista, and have even rolled back to xp. Thank in advance.
