I'm owner of Lenovo Thinkpad T510i with Wifi adapter "Intel® WiMAX/WiFi Link 5150" on board
after recent Windows 7 64bit reinstallation device manager reports about unrecognized network adapter:
When I try to install Link 5150 driver it reports that no WIMAX card found in system.
I tried different drivers for Link 5150 as well as the latest Intel PROSet Wireless but none of them could solve this problem.
Please give these a try:
If the above do not work for you somehow, kindly indicate if it was a clean Windows* installation or if a previous Intel® PROSet Software version was left there; in such case I recommend uninstalling it first. Remember, you may also get the drivers from the system manufacturer's website.
