@ldc:
- I did observe multiple times now, that killing the wpa_supplicant +
reconnecting to the wifi solved the no traffic issue.
- I can reproduce it quite good in the company by changing the floor (and
thus, getting a different access point with the same ssid)
- Does that workaround work
Hi,
Yesterday I ran into a no traffic situation, which was not resolveable by
unloading the wl module:
tcpdump on the wlan0 interface showed me only:
00:21:21.575404 EAPOL key (3) v2, len 117
00:21:21.865239 EAPOL key (3) v2, len 117
00:21:22.385278 EAPOL key (3) v2, len 11
...
At the same I
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
Hello,
yes, it supports 5 GHz and 2.4GHz and it's a hidden SSID. With your two
accesspoint setup, did you try to associate with one AP and turn that off or
force the AP desaccociate the client?

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
Hello,
I build the module with your patch. Thanks for that patch!
I work in a an environment with a cisco-based corporate Wi-Fi solution
which leads to a situation that I roam often. My observation is, that I
suspend, change the building and resume, the no traffic effect occurs.
In difference to
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
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
can see packages
Update:
Since manually doing suspend/resume it a bit tedious i started to do
some load/unload of wl.ko. after ~200 load/unload cycles the wifi
works without problem.
I have not been able to get a failure with the below for about 15
suspend/resume's, and it would be good if more people than me
