No wireless on Dell N5110 with any driver

Question

I've tried installing b43, STA, wl, ndiswrapper, none have worked, so now I'm trying brcmsmac

Problem is, I have this problem when trying to modprobe ANY module:

WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

FATAL: Error inserting brcmsmac (/lib/modules/3.2.0-38-generic/kernel/drivers/net/wireless/brcm80211/brcmsmac/brcmsmac.ko): Invalid argument

Apparently I have bcma and ssb running each time I boot, from lsmod: http://pastebin.com/vBwMmuYB

iwconfig gives:

robawalsh@Dell-Inspiron-N5110:~$ iwconfig

lo        no wireless extensions.

eth0      no wireless extensions.

And here is the output of lspci: http://pastebin.com/eLHXwYaC

I have run sudo apt-get update && sudo apt-get upgrade

Under Network Settings, Wireless isn't even an option.

Answer 1

I wonder if you have backports installed. Please do:

sudo apt-get remove --purge linux-backports-modules-cw*
sudo apt-get remove --purge ndiswrapper*
sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo rm /etc/modprobe.d/blacklist

Reboot and give us your report.
