Did you enable WME on the AP? I remembered that AP would deauth. your client if MIC errors are detected in your frames. Disable WME on both side might help(or to replace your TKIP group key with CCMP). If that still doesn't work, try to turn more debugging message on with: 80211debug +debug +crypto +auth Next time you're disconnected, dmesg may have something like: . . [MAC of AP] send station deauthenticate (reason X) [MAC of AP] send deauth on channel Y . . Cheers, Tai-hwa Liang
