[Bug 721449] Re: slow wifi (atheros driver issue)
I have AR9285 and also experience this bug. I lose connections with remote systems and have low speed. Kernel .35 was fine. There is no working workaround for my issue. ** Summary changed: - slow wifi (atheros driver issue) + slow wifi (atheros [ath9k] driver issue) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros [ath9k] driver issue) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/721449/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry for posting this often, but for my USB device the solution turned out to be even simpler than what I described before: (1) Type into terminal: gksu gedit /etc/modprobe.d/blacklist.conf (2) Add those to lines to the file and save blacklist arusb_lnx blacklist ar9170usb (3) Reboot your system This is all that is needed to make your usb networking device work if you experience this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 721449] Re: slow wifi (atheros driver issue)
So... I finally resolved the issue effectively without any remaining restrictions. But in order to do that I made a rather 'radical' move... I installed the carl9170 firmware and compiled the carl9170 kernel module from compat-wireless package. (This might take about 10-15 minutes of your time) Firmware: http://wireless.kernel.org/en/users/Drivers/carl9170#Firmware-1 Kernel Modules: http://wireless.kernel.org/en/users/Download/stable/#compat-wireless_2.6.38_stable_releases !!! Warning !!! I won't guarantee that this won't harm your system. I will NOT be responsible for any damage. 1) To install the firmware, I ran: sudo wget http://www.kernel.org/pub/linux/kernel/people/chr/carl9170/fw/1.9.2/carl9170-1.fw 2) To compile and install the module, I downloaded and unpacked: http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.38/compat-wireless-2.6.38.2-2.tar.bz2 If it is not already the case you must boot to the kernel 2.6.38 (I had to do this because I was using kernel 2.6.35 until now) Open a terminal and change dir to the one you just unpacked and run: ./scripts/driver-select atheros make sudo make install Either you make a reboot at that point or you run following commands: sudo make unload sudo modprobe 'carl9170' (also have a look into 'ReadMe', it says essentially the same) Unplugging and plugging my usb device in again, I could already enjoy a stable and fast wifi connection. (If at some point you want to uninstall these kernel-modules again just run make uninstall in the directory in which you ran make from...) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry, I forgot one important point: BEFORE running wget in point 1) you will need to change directory to /lib/firmware/ by running: cd /lib/firmware/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Oh, carl9170 already seems to be part of the kernel, so you might just try this: https://wiki.archlinux.org/index.php/Wireless_Setup#carl9170 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 721449] Re: slow wifi (atheros driver issue)
Thank you very much Terry for the workaround and for sharing your experience with us. Unfortunately it did NOT help in my case, even though I tried this little trick with all atheros kernel modules I could find. It's quite disappointing... especially that this regression does not seem to draw much attention by developers. (although I must admit that it doesn't seem to be a grave bug... it is really frustrating, still ...) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721449 Title: slow wifi (atheros driver issue) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
