BCM43228 (14e4:4359) with broadcom-sta "system busy", connection unstable

[Cedric Sodhi]

Hello, I originally had trouble with the "official" broadcom-sta package
(on Gentoo) because the interface was neither appropriately named (it
was called ethX among other things) nor did it work. I then found a
solution for Gentoo in a separate ebuild which contained a couple of
handmade patches. That was about a year ago.

As of recently, the custom ebuild did no longer work (the source tarball
was no longer available) so I gave the "official" broadcom-sta another
try. As opposed to a year ago, it compiled and after reboot, "wlan0"
became available.

However, and that is the problem, the interface is not usable. On dmesg
there are recurring chunks of

cfg80211: Calling CRDA to update world regulatory domain
cfg80211: World regulatory domain updated:

and `wpa_cli` says

in rapid repetition.

In fact, I just noticed that while the connection was unstable for the
first 10 minutes after boot, it is almost completely dead now. Kernel is

3.10.17-gentoo with

CONFIG_CFG80211=m
CONFIG_CFG80211_WEXT=y
# CONFIG_MAC80211 is not set

Thank you

You should try luck with Broadcom's support, see:
http://www.broadcom.com/support/802.11/linux_sta.php
(their post support e-mail).

b43-dev@ is mostly for open source b43 driver.

Thank you. I wasn't sure which address to write to.
