Dell Latitude e5440, Intel Wireless 7260: Not working on ubuntu 12.04

[quilby2]

I have ubuntu 12.04, the wireless works on windows but not on my ubuntu.

I ran this command that I found

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script


and got this:

hi, please post the output of..

uname -mr
lspci -nnk | grep -iA2 net 
dmesg | grep iwl

also you have loaded the b43 wireless driver
that is for broadcom devices,you have an Intel wireless
card. Lets remove that non working b43 driver.
please do..

sudo apt-get remove --purge  b43-fwcutter firmware-b43-installer

thanks.

You are correct, I just ran some commands I found in similar threads.
I removed the drivers like you said, and this is the output of the first command :

uname -mr
3.8.0-37-generic x86_64

lspci -nnk | grep -iA2 net

dmesg | grep iwl
