Issue is in 4.7.0 too.
Wifi *may* stay working for fairly long periods (2-3 hours) in some
lucky instances.
Tests performed:
1. unload/load brcmfmac module.
Result : Interface is stuck in "Link is not ready"
2. suspend system and resume.
Result : Interface is stuck in "Link is not ready"
Adding log (nonworking-rmmod.txt) from when unloading the module too...

Attached to this comment is a debug log (non-working-state_modprobe.txt)
from the brcmfmac module while loading it but network-card failing to
come up as it should.
Module loaded with:
$ cat /etc/modprobe.d/brcmfmac.conf
options brcmfmac debug=0xff roamoff=1

Will attempt to capture some more logs when the card is working and when
goes into the problematic state.

Update: There seems to still be a suspend/resume issue.
After each resume there is a chance that the wifi-card may stop working.
Have not dug into this yet, but at least the system as a whole seems
stable.
Behavior is that reception seems to stop working. It can transmit (and i

Hi Andreas,
Thanks for the assistance... What kernel-version and model of the wifi-
card are you using? Does it behave the same on both 2.4 and 5 Ghz?
For suspend/resume the pm-script seems to make it more stable atleast...
When/if getting the "no traffic bug" it's enough to unload/load the
modul
Hi.
Ok? So you are using ubuntu 15.04? Remember that systemd does not run the
/etc/pm/sleep.d scripts, i use the pm-suspend command to suspend, that does
execute those.. *If* you are using systemd see the following:

Adding a cleaner version of the patch.
issues remaining:
- Current testing is ongoing on the "no traffic" issue, but it seems fairly
stable.
- The "wl" module should be unloaded before suspend and loaded on resume. Makes
it less prone to experience the "no traffic" bug. Do not know how or by who
After a few days of testing the results are:
- During low network utlization i have seen the "no traffic" issue 2 times
during 5 days. Issue can be "fixed" by unload/wait 2 seconds/load of the wl
module.
- Suspend/resume - With unloading/loading the module on every resume i have not
seen any iss
