I have an IMB thinkpad T30. I have just bought a wireless card for it that fits into a slot next to where the modem is underneath the laptop. It has a built in modem so I removed the current modem as it is no longer needed. I then downloaded the driver for this card which is a "IBM High Rate Wireless LAN Mini-PCI Adapter with Modem". The Product Number is - "91P7661'.
I went to this link - http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-42480
I downloaded the drivers that it recommended and ran through the setup. It installed the built in modem on the device fine and I've tested this and the modem works fine, but the wireless card is still an unknown device. I tried to manually update the driver through the device manager and pointed it to the .inf file that was extracted from the driver download but it doesnt like it.
I've added, removed it etc etc but no matter what I do it won't pick up the wireless card installed. It must be the wrong driver for the particular card but I can't find a driver for it anywhere.
