Wifi not working in Ubuntu/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:

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.

    • Thanks Daniel for you updates.

  • Bob Nupp

    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

    • Thank you Bob for your updates.

    • Wolfe Reign

      I can confirm what Bob said. I think i have the dell mini wif card in here, and the instrructs worked on my Dell Inspiron
      1501..thanks your a life saver

  • Daniele Zarba

    hello, i have problem. my wifi bottom does not turn on anymore and once i go in setting of the wife and try to put it one is automatically go off. how i can handle this?

    • 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?

      • 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?”

            I have mint 17 ..but once I do what you wrote ..then at the last step after firmware install ..it ask me to enter dvd to cd rom ..and I do but even I press enter nothing happens

          • Can you please post exact error?

          • Tomas Tran

            ah Santosh …thanks for note ..meanwhile I tried other things base on forum but no success…I also several times reinstal just to have fresh install when trying ..so I also open topic on other forum …anyway ..this is my log now

          • Hi Tomas,

            As per you logs, the last one should work. I found same info on below mentioned link:

            http://community.linuxmint.com/tutorial/view/796

            Also, the compatibility table on LinuxWireless (link below) shows that your device is compatible to drivers.

            http://www.linuxwireless.org/en/users/Drivers/b43/#supported

            Please try the command shown in the first link here. Please let me know if that worked for you.

            Santosh

          • Tomas Tran

            Hi Santosh,
            on the other thread they advised me …below link …and it works for me ..so happy I am now

            bye bye Win

            enjoy the day!

          • Cool. It seems to me as it is similar to the last one in the post additionally it is removing the soft lock. Thanks for pointing there.

            Best Regards,

  • 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).

    • Thanks. I too think the last one is working for most of us.

  • Scot StClair

    The tidbit about the additional drivers window was a lifesaver! Saved what was left of my hair.

    • Glad that it helped you. 🙂

  • i had some issues with wifi connectivity on mint 17, i was able to connect to wifi network, but was not able to use the Internet/load websites, i tried all of the solutiions described here, the first two wont work for me but last option worked 🙂

    Thanks 🙂

    • Thanks Ajith. Glad that it worked for you.

  • Joshua Rodgers

    This post was a life saver once again. I was running Ubuntu off a LiveUSB and the step in the additional drivers window worked, however after doing the full install no such luck. After finding an ethernet cable, it ended up being the last one that did the job. thanks a million.

    • Thanks Joshua. Glad that it helped you.

  • Ganteng Polnotok

    Dear Santosh, thanks for the tips. I already testes all yu wrote but it seemed not working to me. I tried to iwconfig and its result ‘lo no wireless conn, etho0 no wireless conn’.
    What should I do? Please help. I use dell mini inspiron mint 15.
    Thanks

    Whomever posted these solutions I can’t thank you enough! The 3rd option finally got my wifi working. 2 days ago I installed Linux Mint on a 2005 HP Pavilion that used to run XP. Everything installed just fine except there was no wifi option anywhere. I tried everything to turn on the wifi and nothing worked. I was ready to reinstall XP-since I need to use the wifi. Well option 3 above got the wifi working on my machine. I am brand new to the world of linux and am very thankful for all your help.
