Broadcom 4331 deauthenticating very often

Hello,

I have this broadcom 4331 wireless on my MacBook Pro 8.1, dualboot OS 12.3/OSX. Thanks to lwfinger’s tutorials and scripts I could make it run, but… it deauthenticates very often, sometimes after some minutes, sometimes within seconds, thus internet is almost unusable over wifi (with ethernet everything works perfect).

So according to the sticky thread I hope to give the right details…:

a part of dmesg:

I’ll post iwlist scan in next message, as the forum says, my post was getting too long…

I did not see any disconnects/deauthentications in your dmesg output.

It was here:


[10939.376321] wlan0: deauthenticating from 00:02:cf:55:9d:cc by local choice (reason=3)
and [10942.751143] wlan0: deauthenticated from 00:02:cf:55:9d:cc (Reason: 1)

However, the problem is solved: I simply had to reboot the computer…

(While searching for reasons for extremely low wireless speed I found your hint about disabling ipv6. So I started Yast, disabled ipv6, and waited. Still many of the above mentioned messages appeared. But since I rebooted everything works. No more such messages. So sorry for the noise…)
