So, I once again thought of getting serious with my Linux skills and installed Ubuntu 14.04.2 LTS on my Dell Latitude D830.
After the fresh installation, I was not able to:
- See the Wi-Fi icon blinking on my laptop
- See the "Wi-Fi Networks" in the network list
- Connect to the any Wi-Fi network
After spending many days and 2 nights, a small five-liners helped from this post.
sudo apt-get remove --purge bcmwl-kernel-source sudo modprobe -rf b43 sudo modprobe b43
sudo iw reg set GB sudo sed -i 's/^REG.*=$/&GB/' /etc/default/crda
