[Bug 931168] Re: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11
I tested a recompiled brcmsmac module with the patch mentioned above : not better. I also tried to add the patch from https://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=edc7651f3a4ffa7fca37d92401562694121512ad : not better. I had a further look at the changelog. This commit looks more promising : https://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=898d3c3b2462cd439edb575f43b732425693aff0 It changes the way brcmsmac reads info from sprom, by using the bcma module. This includes changing the way it reads the country code. So it might be a good candidate for a backport test. Unfortunately, it seems more difficult to backport this commit. The patch does not fit well on the source code of kernel 3.2.0-31, and I suppose it would also need to backport some code for bcma module and recompile it. I did not manage to compile brcmsmac this way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931168 Title: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/931168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 931168] Re: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11
OK. Thanks Christopher. Regarding a potential backport, it certainly does not come from an updated firmware : the firmware files /lib/firmware/brcm/bcm43xx-0.fw and /lib/firmware/brcm/bcm43xx_hdr-0.fw are the same when used with both kernels on my machine. So it comes from an update in the driver itself. This commit might be the one that should be backported : https://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commitdiff;h=6b8da423315b5ea7573c8c3a3925941b9a1c3932 At least the commit description corresponds to the symptoms : with kernel 3.2.0-30, I get an US country code, and with 3.5.0-14, I get an 00 country code If I find some time to work on it, I'll try to recompile the 3.2.0-30 kernel with this commit, to see if it works -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931168 Title: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/931168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 931168] Re: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11
Yes, I would like to keep my netbook with 12.04.x LTS if possible. In any case, it's not just a question of me. If I understood correctly, the kernel for 12.04.x LTS will be upgraded to improve hardware support in the future (because it's a LTS). IMHO, this could be a fix that might be included in this process. I tested the kernel 3.5.0_14 from quantal repos on my 12.04 netbook : it detects all 13 channels. So the fix is definitely in the kernel. I had to install http://packages.ubuntu.com/quantal/i386/linux-image-3.5.0-14-generic, http://packages.ubuntu.com/quantal/i386/kernel/linux-image-extra-3.5.0-14-generic, http://packages.ubuntu.com/quantal/linux-headers-3.5.0-14, and http://packages.ubuntu.com/quantal/i386/linux-headers-3.5.0-14-generic I had a quick look at the changelog on git.kernel.org : it looks like the firmware for brcm4313 has been upgraded. If we're lucky, backporting this firmware might be enough? Of course, I'm willing to help and test. Regarding the status of this ticket, I don't see why it should be closed a Invalid. IMHO, it should be closed as Fix released for Quantal, and still Confirmed for Precise (until we find a way to backport the fix) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931168 Title: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/931168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Mossroy, thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - Quantal Quetzal. This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please do steps 1 and 2 of the SRU Procedure [1] to bring the need to a developer's attention.

[Bug 931168] Re: 14e4:4727 brcm80211 Wifi driver : cannot connect to channels11
This issue seems to be solved in 12.10 Quantal beta 1. I ran it with a live USB : wifi on channel 13 is detected and ubuntu connects successfully to it. iw reg get = 00 iwlist wlan0 channel = all 13 channels It's using the same brcmsmac driver as in 12.04.1, so I suppose it might come from an update in this driver? In any case, jt's solved in 12.10. That's good news! I'd like to help investigate if there is a way to backport this fix in 12.04, because it's a LTS. I suppose I could test with an upstream or backported kernel. Which version should I test? https://wiki.ubuntu.com/KernelMainlineBuilds ?

Mossroy, glad to hear it is fixed for you in Quantal.

Christopher, The tests were made on Precise with all updates (12.04.1). I just reinstalled the netbook with Precise, because wifi did not work any more after the ndiswrapper test (maybe I did something wrong in the uninstall process). Anyway, I won't have the time to run the tests on Quantal for now. I'll try to do it later.
