What's going on with my wireless?

Solution 1:

Maybe there is a problem with the n-channel of your wifi.

Give the following terminal commands a try:

sudo rmmod iwlagn
sudo modprobe iwlagn 11n_disable=1

Try browsing again and if there is an improvement, make this change permanent by creating an 'options' file:

gksu gedit /etc/modprobe.d/options.conf
and add the line
options iwlagn 11n_disable=1

Hope this will help.
