Broadcom BCM43225 Wireless Shows Not Connected then Hardware Disabled
Greetings.
I'm running Jessie on an Acer Aspire 5745DG laptop with a Broadcom
BCM43225 wireless chip. Wireless LAN has always worked flawlessly
until recently when it started disconnecting abruptly, showing not
connected, hardware disabled then disappearing from Network Manager.
The laptop only has FN+F3 WiFi on/off toggling.
This can happen anytime form 10 minutes to 1 week of working with the
only way of recovering being a reboot. Both the open-source "bcma" and
proprietary "wl" kernel driver modules produce the same results.
I have since purchased a USB WiFi adaptor (Realtek RT8188eu) as a fall
back measure but would prefer to have the inbuilt PCI WiFi adaptor
working again. Any help will be greatly appreciated.
My System.
a) Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)
b) Driver Modules: brcmsmac, mac80211, cfg80211, bcma, brcmutil, cordic
c) Kernel: Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u4
(2016-02-29) x86_64 GNU/Linux
What I have Tried
a) Restart Network Manager
b) Unloading and reloading the drivers
c) Trying the proprietary wl driver
d) Setting REGDOMAIN in /etc/default/crda to KE, IN, US etc.
e) Installing rfkill and ensuring Wireless is NOT soft or hard blocked.
f) Googling and trying instructions at
