I updated my Toshiba Satalite M-55 laptop with Lubuntu 14.04 but after update I have super slow or no WiFi. This is what I have when I type $ iwconfig:

iwconfig

          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:25:9C:D9:FC:74

lo        no wireless extensions.

Do:

echo "options ath5k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath5k.conf
sudo modprobe -rfv ath5k
sudo modprobe -v ath5k

Change the encryption to just wpa2 (CCMP)(AES) not (TKIP) if you have that option it will work best.

Change the channel to 1 or 11 they usually work best. Save the router configuration, then reboot router and unplug wired connection.

Set your wireless settings in network manager to match the screenshots.DNS SettingsIPV6 Setting

Then reboot.
