Dell Inspiron N7110 Wireless Driver not working

Question

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?

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.

I realize this is an old question, but I just ran into this issue and it took some time to find an answer that worked. For me, I needed to go into the BIOS under "Advanced" settings and toggle "Function Key Behavior" to be "Function Key" instead of "Multimedia Key".

Then, when I was back in Linux I could use Fn-F2 to toggle on the wireless network interface. (This is the hardware switch.) At that point everything worked automatically.
