This iwlwifi driver seems not stable when I hold laptop moving inside a large office, between multiple APs, everytime I moved to a new place, the wifi link becomes inactive, and I need to wait 5 minutes or longer to wait iwlwifi stable, networkmanager get a new ip address; quite annoying, [root@archtop ~]# lspci -D -nn -k -d 8086:4238 0000:03:00.0 Network controller [0280]: Intel Corporation Centrino Ultimate-N 6300 [8086:4238] (rev 35) Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN [8086:1111] Kernel driver in use: iwlwifi Kernel modules: iwlwifi in the large office, it's using WPA2 enterprise encryption with MSCHAPv2 domain user/pass authentication, Last iwlagn driver in my Ubuntu-10.10 default kernel (linux-2.6.35.X) on the same computer same networkmanager/wpa_supplicant software same office working wonderful, moving smoothly between multiple APs, At home, even I set wireless router to no any encryption/authentication, this new kernel would becomes wifi link down every couple of hours, while another laptop and same Ubuntu-10 on this laptop could work smoothly, Thanks,
