I have a german based windows XP Fugitsu siemens Laptop. I have a wireless card which is not working. i had the wireless internet working last night but i turned it on this morning and now the computer doesnt even register that i have a wireless card in. Wireless card is still in computer, checked already. wireless is turned on with the switch. I tried to use the disc from my internet company for the wireless modem and connect to the modem but it says that there is no wireless card connected. I even went into the command prompt to see what the mac address was for the wireless, but its not even registering that there is a wireless card. What do i do now?
