Wifi not working in Ubuntu/Linux Mint 14



Categories: Linux Tags: linux wi-fi in linux mint 14

I am a long time Ubuntu user. Today, I thought of giving a try to Linux Mint. I installed it and as per my expectation wi-fi was not working with out of box installation. I tried few of the options, which I am sharing here to be useful for someone else.

Since I came from Ubuntu, I looked into System Settings from the main menu and looked for Software Sources.

In Software Source, switch to the Additional Drivers tab. Select “Using Broadcom 802.11Linux….” option in the tab. Click Apply Changes and close the window. Ideally it should load the required proprietary drivers for WLAN card.

But, it didn’t work for me. So, next I moved to Google for searching an existing solution to my problem and found a discussion on this forum and this page. This link is of our relevance since Linux Mint 14 is based on Ubuntu 12.10. I tried the options available in answer section one by one in the given order.

I am putting the given options here again:

You can fix wifi problems using two methods:

sudo apt-get update && sudo apt-get upgrade

Then reboot your system.

sudo apt-get install linux linux-headers-generic kernel-package
sudo apt-get install --reinstall bcmwl* firmware-b43-lpphy-installer b43-fwcutter

Finally, reboot your system.

If that didn’t help, try these commands:

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer b43-fwcutter
sudo reboot

For me, the last option worked. Now, I am publishing this post using my wi-fi connection. Please comment, which one worked for you?
