I have Ubuntu 14.04. I've tried connecting to the AT&T router in my apartment, but I cannot see the symbol. I've tried installing drivers for the WiFi Router from Additional driver but there no drivers in the list.

output of the lspci command is:

If you have the installation USB, insert it and and drill down to pool > restricted > b > bcmwl and drag bcmwl-kernel-source to your desktop. Do the same with pool > main > d > dkms and drag dkms to you desktop. Then install:

cd ~/Desktop
sudo dpkg -i dkms*.deb
sudo dpkg -i bcmwl*.deb
sudo modprobe wl

Your wireless should now be working.

  • dpkg: error processing archive dkms*.deb (--install): cannot access archive: No such file or directory Errors were encountered while processing: dkms*.edeb – user2607744 Sep 13 '14 at 19:20
  • Is it on your desktop? cd ~/Desktop && ls – chili555 Sep 13 '14 at 19:22
  • I copied the file in the Desktop folder of my Windows OS and not Ubuntu OS. :) – user2607744 Sep 13 '14 at 19:25

You need to install the drivers for your Broadcom chip. To do so, open a terminal.

Run these two commands with a working internet connection (Use Ethernet):

wget https://launchpad.net/ubuntu/+source/bcmwl/6.30.223.141+bdcom-0ubuntu2/+build/5254885/+files/bcmwl-kernel-source_6.30.223.141%2Bbdcom-0ubuntu2_amd64.deb -O driver.deb
sudo dpkg -i driver.deb

Reboot and enjoy your WiFi!


If you cannot connect to the internet, you can of course download the file here on Windows, save it to a USB stick, reboot into Ubuntu, mount the USB stick, and double-click on the .deb file.

  • @user2607744 Can you run this command in your terminal? sudo dpkg -i /path/to/your/flash/drive/bcmwl-kernel-source_6.30.223.141%2Bbdcom-0ubuntu2_amd64? – Kaz Wolfe Sep 13 '14 at 7:11

I'm currently having the same issue.

I'm using Android 4.4.2 and I accessed the Internet via USB Tethering. The option was hidden in my settings so I used the free "USB Tethering Pro" app for the job.
