broadcom drivers for 14e4:4365

[Sinisa]

This annoying bug is found on broadcom drivers for 14e4:4365

i even downloaded and compiled latest broadcom drivers at
http://www.broadcom.com/support/802.11/linux_sta.php

and i applied a patch from here
https://aur.archlinux.org/packages/broadcom-wl/

Its on Ubuntu 3.13.0-32.57-generic 3.13.11.4

What happens is that wireless signal is lost every few minutes, sometimes on every half hour or so. I guess it depends on strength of the AP signal.

Also, every signal to AP is show as "weak" no matter how close i am to the AP it self.

This is from dmesg
