Comment 5 for bug 1679535

I have a similar issue with the bcmwl-kernel-source for Broadcom BCM4359 802.11 Hybrid Wireless Controller 6.30.223.271 (r58733). If I reset network service, the wifi network works for a few minutes:

sudo service network-manager restart

This is what dmesg says:

wl: loading out-of-tree module taints kernel.
[ 14.318743] wl: module license 'MIXED/Proprietary' taints kernel.
