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.

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.
