Wireless can not scan network

I'd been using kernel-ck-core2-2.6.38.6-3 for a long time but I upgraded my kernel up to linux-ck-corex-3.2.1-4 two weeks ago. Now I have strange problem related with my wireless card. I'm using Networkmanager and it doesnt show any wireless network anymore. Sometimes it's appeared only for a moment and then is dissapeared again. According to logs supplicant manager state always changes down - idle - ready and then to idle - down, and this loop continues until finding any wireless network but as I said before that it is dissapeared in five seconds again. Most of time this loop continues for hours.

brandname of my wireless card

lspci | grep -i net
02:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)

lspci -vnn | grep 14e4
02:00.0 Network controller [0280]: Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)

and wireless modules

lsmod | grep wl
wl                   2557355  0 
lib80211                3981  2 wl,lib80211_crypt_tkip
cfg80211              172260  1 wl

I've tried all packages of broadcom drivers, broadcom-wl from aur,  broadcom-wl-ck, broadcom-wl-ck-corex from ck-repo and also broadcom hybrid linux device driver from broadcom.com. I tried all of them though the last one i think, is same as broadcom-wl package from aur.

Is there any suggestion?

Re: Wireless can not scan network

Drop wl, use brcmsmac instead. If not even that will work, there's also b43 (you'll need to compile your own kernel for that though).

Re: Wireless can not scan network

Thank you, I think i may need to add blacklist for bcma module which affects Linux kernels 3.0 and 3.1.

Re: Wireless can not scan network

Really strange, I uninstalled broadcom-wl-ck-corex driver and made new one from website of broadcom.com and also blacklisted bcma, b43 and ssb modules yesterday. Everything gone well at my home, reboot one or two times for the test. Now in my office it's again crazy and supplicant manager state always changes ready - down vice versa.
