Hi Intel Linux Wireless group,

Since 3.2-rcX, it seems no more iwlagn driver? 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,
