I'm using ubuntu 12.04 with an Atheros wireless card. My internet speed in W7 is great. My internet speed in Ubuntu 12.04 at a university network is great. My internet speed in Ubuntu 12.04 at my home network is really slow.

Some solutions I have tried but didn't work:

  • Disabling IPv6
  • Running the following code:

    sudo ifconfig wlan0 down
    sudo rmmod -f iwlwifi
    sudo modprobe iwlwifi 11n_disable=1
    sudo ifconfig wlan0 up

Thanks for the help!

sudo -s
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

Found this code on here somewhere. It fixed my problem. Might not work immediately though. I had to do a restart.
