hi,
My network card is
04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
Firmware installed is b43.
b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07)
I dont have wl installed. Initial scanning shows the AP correctly and wpa_supplicant seems to associate it. I can get network access, which lasts for about 20 seconds. Even after that the AP is still associated.
Checking after a minute shows AP is no longer associated. Scanning returns no result after that whatsoever. Here's the dmesg output.
~]$ dmesg | grep wlan0

Any ideas? thanks.

okay so disabling the QOS of the driver seems to solve the problem. I ll just test it some more time to make sure.

wish i found this before posting here...adding the line
options b43 pio=1 qos=0
to /etc/modprobe.d/b43.conf did it. Driver does warns that disabling the QOS would result in a decrease in performance, but i couldnt find any other solution. Any ideas on performance of b43 with these settings vs wl?

I'm having a very similar problem, just with bcm4322 (macbook pro 7.1)
I've used Arch on it before, and never had this problem before, but I'm getting the same error message:
ieee80211 phy0: wlan0: No probe response from AP 00:23:54:37:e9:19 after 500ms, disconnecing.
I'll try your workaround, but unless the setting you suggest used to be the default, which I doubt, something smells fishy...
Especially since I've found that I don't always have this problem - I can sometimes boot up, and every-thing's fine, but more often it just constantly disconnects.
Beetles and bacteria are vastly more successful than humans in terms of survival.
