[Bug 941695] Re: Broadcom BCM4313 random AP disconnects and network hang
I am getting a similar error using the BCM4313 card on our Acer Aspire One 722 netbooks running 12.04. They see the network and connect using the brcmsmac driver, but will occasionally stop being able to transfer over wifi. Network manager says the netbooks are connected and they have an IP address, but they cannot ping anything. That lasts for about a minute and then they can load webpages again. It seems to happen under heavy network load on the device (but not on the network at large). Running dmesg | grep iee shows that it is constantly reporting the following info: [ 637.012316] ieee80211 phy0: brcms_c_dotxstatus: INTERMEDIATE but not AMPDU [ 637.012533] ieee80211 phy0: brcms_c_dotxstatus: INTERMEDIATE but not AMPDU [ 645.588396] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 648.650949] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 649.676131] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 650.595325] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 654.590220] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) This error and the messages only appear on our school network. The netbooks work fine on my home network and don't have those log messages. Our school network does use qos for VoIP, but I am not sure why that would have to be reported over and over again. Also I don't know what the AMPDU message is about at all. The same netbooks with an Atheros card have no issue connecting and staying connected, so it seems like an interaction between some aspect of our school network and the BCM4313 card in Linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/941695 Title: Broadcom BCM4313 random AP disconnects and network hang To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/941695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not running it as an AP, I'm merely suggesting that we test with different security modes on the AP (WEP, WPA/WPA2 w/ AES or TKIP) since different AP's sometimes behave slightly differently with different hardware as was the case with my PSP. I only mentioned my PSP because it seemed unusual that it didn't work with the TKIP but did on a previous AP I had.

My experience has been that it works well with some wifi access points/routers and locks up with others.

Well, i will try to describe what happens to me, even with my poor english. Apologies if you can't understand what i mean. - Ubuntu 11.10 or 12.04 beta 2 and daily releases. - Kernel 3 and 3.2 - The indicator in HP 425 isn't recognised. Even if the wireless connection works normally, -except for the hotspot -the indicator is in red, not in white, as is turned off. - This issue is not present in 11.04. It says in "Connection Information" is using the wl controller. - The controller in 11.10 is brmsc or something like that, i don't remember exactly. - When, in 11.10 and Kernel 3 and newer versions, i try to create "New wireless connection" in Unity it tries to connect to de AP but never success. It says as the password is not recognised, -wow, is created and don't recognise is own password... haha - In Gnome Shell i push the button "Create Hotspot" with the same result. - I tried in all configurations create the hotspot but never can create the connection. As you could understand, the AP is necessary in my work, because we haven't always a Internet connection, so, i we want a on line work with a collaborative app -as Gobby or Abiword -we need the hotspot.

Probably not helpful to you but it just happens for me. To be honest, I've been testing by downloading a Ubuntu DVD ISO and at some point it will happen but I don't have to be downloading for it to happen, that's the thing. I've been trying to find a pattern but I've not found anything consistent enough, it just happens. My only thought was perhaps it's something to do with A-MPDU causing the hang but what I don't know because my experience with kernel hacking and even C is very limited.

[Bug 941695] Re: Broadcom BCM4313 random AP disconnects and network hang
So you have tested the patch from the fedora bug, "brcm80211: smac: fix endless retry of A-MPDU transmissions", and found that it didn't help, correct? Really I think that's only intended to be a fix for the warning that's triggered in brcms_c_wait_for_tx_completion(), which seems like it was a symptom of the problem and not related to the cause. These attempts to fix the warning don't seem to be getting at the root of your hangs and disconnects. I'd say that some of the AMPDU messages are normal, especially in noisy RF environments, but an extreme number of them may be indicative of a problem. The illegal channel messages are more interesting. The driver is trying to transmit some packets, but the hardware comes back with an error that the comments in the code note as "channel mismatch." The driver won't retry when it sees this error, so the BA timeout messages are a result of the code iterating through all the fragments that were part of this failed transfer. I'm going to have to go through the code more to try and better understand what it all means. Once you get into this state, do you continually get a stream of these messages when trying to use the network until you use network manager to reconnect? Can you explain exactly what you're doing when you use network manager to reconnect? I.e., do you disable and re-enable wirless, or do you just disconnect and reconnect to the network? Can you also trigger this error and take note of whether the channel number in the "illegal channel" messages matches the channel the AP you're connected to is using?

I'm not sure if this will help with this issue but I came across this: https://bugzilla.redhat.com/show_bug.cgi?id=787649 which is the exact same issue I'm having. There is a patch but nobody can confirm it has been fixed. I've also had a go myself but it was a real pain to find a working wireless stack that compiles and loads correctly. I'm not even sure if I can add the patch from that bug report here? Is that the done thing? Seems dead on the upstream front, I guess I'm one of very very few people this happens to. ** Bug watch added: Red Hat Bugzilla #787649 https://bugzilla.redhat.com/show_bug.cgi?id=787649 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/941695 Title: Broadcom BCM4313 random AP disconnects and network hang To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/941695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Tags added: kernel-request-3.2.0-17.27 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/941695 Title: Broadcom BCM4313 random AP disconnects and network hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/941695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc5 fixed the issue, the tag would be: 'kernel-fixed- upstream-v3.3-rc5'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
