Wifi not working in Linux Mint 14

By | April 30, 2013

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:

1. Either connect to the internet via wired connection and run this command:

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

Then reboot your system.

2. Or use the following commands:

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?

    sudo apt-get remove bcmwl-kernel-source

    sudo apt-get install firmware-b43-installer b43-fwcutter

    sudo reboot

    This is what worked for me. That being said, I did all the steps mentioned above.

    I tried a fresh install of Linux Mint 15 (Olivia) with Dell Inspiron
    1501. Wifi is now working after running only these two commands:

    sudo apt-get install firmware-b43-installer b43-fwcutter

    sudo reboot

      Which version of Mint are you using? Did you try above steps?
      I use to face this in earlier version of Ubuntu until I install the proprietary drivers for Broadcom Chip.

    I attempted this process on a Dell Inspiron and I got to :
    sudo apt-get install firmware-b43-installer b43-fwcutter

    The response was:
    Unable to locate package firmware-b43-installer
    Unable to locate package b43-fwcutter

    And now I can not open my Package Manager.

      What is version of Ubuntu/Mint are you using?

      • http://dbmediapublishing.com/ Joshua Baer

        I am using Petra xfce.
        Since it was a fresh install, I simply ran it again and it resolved the software manger disappearing.
        I should add, that I have added the above mentioned drivers and I still am having issues connecting wirelessly.Do you guys know of some docs that explain what I should expect while I connect via wifi? I am not sure if I am having a computer issue connecting, or if I simply do not have my config correct?

          Unable to locate package firmware-b43-installer
          Unable to locate package b43-fwcutter

          The above error seems to be related to repository. As you said you are running these commands on fresh install, I suspect if you ran

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

          command. Please run these commands and they will update the repo information and then try running

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

          Let me know if this works. Also, I could not get your question on “what I should expect while I connect via wifi?”

    This posting has been a constant life-saver as i’ve been trying out various Linux distros on my Inspiron 1501 (Sempron). Thank you.

    I couldn’t seem to get the 1st two methods to work, but the last one works every time; though i sometimes have to reboot & enter the commands again (could be user error).
