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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
