    Question Slow wireless connection with ath9k driver in ubuntu 11, 12 and 13

    Hello everyone,
    I'm having troubles to get a acceptable signal strengh in Ubuntu with my new laptop. I followed the instructions of this post, but had no changes at all.
    Code:
    h_nik@pt-notebook1:~$ lspci -nnk | grep -iA2 net

    I'm already looking for a solution for weeks. I even installed different Ubuntu versions. Currently I'm using Ubuntu 13.04.

    Thanks

    Re: Slow wireless connection with ath9k driver in ubuntu 11, 12 and 13

    Deactivate the hardware encryption of the driver:
    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k

    Thank you for the quick reply!
    I followed your instructions, but there were no changes at all.

    Here is the terminal's output if it helps anyway:
    Code:
    h_nik@pt-notebook1:~$ echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    [sudo] password for h_nik: 
    options ath9k nohwcrypt=1
    h_nik@pt-notebook1:~$ sudo modprobe -rfv ath9k
    rmmod ath9k
    rmmod mac80211
    rmmod ath9k_common
    rmmod ath9k_hw
    rmmod ath
    rmmod cfg80211
    h_nik@pt-notebook1:~$ sudo modprobe -v ath9k
    insmod /lib/modules/3.8.0-16-generic/kernel/net/wireless/cfg80211.ko

    insmod /lib/modules/3.8.0-16-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko nohwcrypt=1

    Try pure WPA2-AES (CCMP) encryption.

    I made this changes in my router's configuration, but nothing changed.

    I don't think it's a good idea to solve it like that. Wouldn't I have the same problem on other routers, using TKIP, again?
    Thanks

    Post the content of:
    Code:
    gksudo gedit /etc/modprobe.d/ath9k.conf
    How slow is your connection?
    Thanks
