Title:
14e4:43a0 [MacBookAir6,2] wireless unable to connect after tainted
kworker
Status in bcmwl package in Ubuntu:
Expired
Bug description:
At some point sooner or later in any session the wireless is no longer able
to connect to the network.
I've included at the end the output of dmesg.
I'm not sure if this is a bug in the kernel or in a module.
This is my card:
03:00.0 Network controller: Broadcom Corporation BCM4360 802.11ac Wireless
Network Adapter (rev 03)
Features of this bug:
- reloading the wl and cfg80211 modules does not fix the problem.
- when this happens I can not use my USB netgear WG111v2 (which works
before it happens).
- other machines on the same network stay connected no problem, including a
different machine with a broadcom chip (BCM5906M Fast Ethernet PCI Express (rev
02)).
I'm sorry that I can't give more information...
please let me know if I can.
