[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
@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 for your no traffic situations, too? With having looked into the code, I bet the crypto WPA stuff is done with the wrong (old, before roaming) BSSID in the keys or challenge response or whatever. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 was able to use the same (hotel) accesspoint with my android phone without trouble. After a reboot (and a update to 4.1.4), the Wifi worked. One observation: I remember the kde network manager thing telling me the Wifi was WPA while it was not able to connect. After the reboot the working variant is WPA2-PSK. Maybe the wpa-supplicant got wrong info from the driver (via cfg802 ) rgds, j -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 issues. - No crashes or hangs have been seen during usage or at resume as can be experienced with the standard ubuntu-patches. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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: http://askubuntu.com/questions/620494/ubuntu-15-04-suspend-doesnt-run-pm-suspend I'm also running a MBP retina with the same card so should be easy to make sure we have the same issues.. Will upload a cleaner patch now..

[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 that should be handled.. ( with consideration for systemd and the old /etc/pm way of doing things on suspend/resume. ) ** Patch added: monolithic.patch https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+attachment/4436448/+files/monolithic.patch ** Patch removed: merged-patches.patch https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+attachment/4434651/+files/merged-patches.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 your test-setup I can be sure, that the MAC (bssid) is different, as the hotspot I was associated to is not longer in reach. I just added the pm-script and will have a look at the effects. Are you sure that removing wl is enough? Could the cfg802-stuff have 'wrong MACs' stored? rgds, j -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 module. It *may* take a few tries but the link comes back at least.. But i think that since you suspend (and unload the driver) it should perform better than before at least During a full day of normal usage i have lost my link once, so it's an improvement... unload / wait a few sec / load worked for me straight off today.. Yesterday i had to reload it a few times, but then i did not wait at all between unload/load, but it succeeded to come back anyway. Main part of the patch is for 4.x support, but there is a couple of things to prevent complete system-crashes. (Think it was in 3.18 or 3.19 that behavior started.) I'm currently just trying to figure out a way to trigger the issue here, in a reproducible way, to allow for some easier debugging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 arriving on the router) EAPOL key packages during the association-requests but no replies are received. It does manage to do scans via wl dev wlan0 scan so the radio-part does seem to be working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478592 Title: bcmwl-kernel-source fixes [Patch] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1478592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1478592] Re: bcmwl-kernel-source fixes [Patch]
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 could test it as a workaround. A possible workaround, until the real issue has been resolved could be to create /etc/pm/sleep.d/09_brcm_wl with the following content BYMMW: #!/bin/sh case $1 in resume|thaw) date /var/log/brcm_wl.log echo Loading wl module /var/log/brcm_wl.log /sbin/modprobe wl ;; suspend|hibernate) date /var/log/brcm_wl.log echo Removing wl module /var/log/brcm_wl.log /sbin/rmmod wl sleep 5 # to allow for network-manager and other things to finish before system is suspended.
