I am running Ubuntu 12.04 on my Toshiba Satellite C855 and cannot connect to any wireless networks. When I run lspci in Terminal, it shows:

00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09)

I have tried downloading the Broadcom STA wireless driver, and it shows as activated in Additional Drivers, but it doesn't seem to be making a difference. Please help!

    Why do you try the BroadCom driver when lspci shows you have a Realtek?

  • Weird how the Additional Drivers would offer you a Broadcom STA driver when infact you have a Realtek adapter...

  • Did your wireless work fine at fist install, and then quit after an update? Feb 27, 2013 at 18:53
  • My wireless hasn't worked since I have installed Ubuntu Feb 27, 2013 at 20:01
  • Also, I have no clue what I am doing. Contrary to what my friends may think, I am no tech wizard and in fact this is my first time using Ubuntu. Simple instructions would be very helpful if anyone can find a solution. Feb 27, 2013 at 20:13

first, in the terminal run:

sudo apt-get install linux-headers-$(uname -r) build-essential

It's probably a good idea to remove the broadcom stuff:

sudo apt-get remove --purge bcmwl-kernel-source

download your driver from the Realtek site (RTL8188CE)

scroll down to the Unix(linux) section, make sure you download the driver for the kernel 2.6.24 (and later). Select the mirror closest to you, and save the downloaded archive in your Downloads folder. Right-click and select "extract here".

in the term run

cd ~/Downloads/rtl_92ce*
sudo su
make install
exit

Wait for magic to happen. Reboot. Hopefully enjoy working wifi. Report back

  • and a lot of other stuff that I don't really find a point in putting into comments. after which it left me with: justin@justin-Satellite-C855:~/Downloads/rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0012.0207.2013$ and nothing had changed. Feb 28, 2013 at 0:38
  • did you reboot? If yes post output of lspci -v | grep -iA 10 'network' and lsmod Feb 28, 2013 at 2:17
