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.
[ 14.318744] Disabling lock debugging due to kernel taint
