First of all, I'm a complete Ubuntu noob. Without thinking I installed the HWE update and now 14.04 won't detect WiFi

Even Ethernet isn't detected. I am using my phone to write this. Please suggest a remedy.

I was using broadcom wireless driver and now in the additional drivers tab it says This device is not working.

  • Please edit your question to add the result of these terminal commands: lspci -nnk | grep 0280 -A2 and also: sudo modprobe wl – chili555 Sep 3 '16 at 13:02
  • Says module wl not found. – SilverSlash Sep 3 '16 at 13:05
  • And the other command?? – chili555 Sep 3 '16 at 13:09

  • In order to install the driver for the wireless, we'll need to identify and fix the ethernet. Please also show us: lspci -nnk | grep 0200 -A2 – chili555 Sep 3 '16 at 13:46

First, let's get the ethernet going. The r8169 driver is troubled by auto-negotiation. Let's turn it off and see if it connects:

sudo ethtool -s eth0 autoneg off

Assuming you connect, let's install the wireless driver:

 sudo apt-get install bcmwl-kernel-source

Finally, let's make the auto-negotiation permanent:

gksudo gedit /etc/rc.local

Use nano or kate or leafpad if you don't have the text editor gedit. Right above the last line exit0, add a new line:

ethtool -s eth0 autoneg off

Proofread carefully, save and close the text editor. You should be all set.

  • Thanks for guiding me through every step of the process! I was ready to give up on fixing this, install 16.04, and loose most of my data! – SilverSlash Sep 3 '16 at 14:24
