@davidyu
 Thanks, it seems you are using the same type of adapter for your T60, as I am having bad experience with on more ThinkPads from the R-series, and that too have been reported not working above. What is different is that you are probably using a Certificate (LEAP) and WPA or WPA2 Enterprice right ? - where my bad experiences with this adapter type (and the ath5k module) is based primarily on WPA and WPA2 Personal or Webbased auth. on an Enterprise Cisco network and partly WPA/WPA2 Personal on different types of other SMB/home routers. From this I wonder if the bug could be related to an issue with the supplicant instead, and I try to see if I'm able get expected performance with a WPA/WPA2 Enterprice setup.
Are you able to get normal max speed (for 54G) around 18 to 22 Mbps (download) on your setup, or just as I experience less than 1 to 2 Mbps ?
