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:

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
