I've been trying to figure out how to get my wireless driver to work since I installed Linux a month ago because Windows was crapping out on me. I'm new to Linux, so I'm unfamiliar with how to get certain things to work. Any suggestions?

Welcome to AskUbuntu! You might want to give this question oon troubleshooting wireless issues a look. It might also be useful to post the output of the commands posted on the answer there into your question here so people know exactly what hardware you have. – Oyibo Feb 12 '13 at 7:46

This had worked for me, but haven't figured out yet how to make it permanent.

Open terminal with Ctrl+Alt+T and type the following commands:

sudo rmmod -f iwlwifi 

It may ask you to input your password after you press enter

sudo modprobe iwlwifi 11n_disable=1

The above will disable the N mode on your wireless card and it should start working.
