I am a new Ubuntu user and I don't have much knowledge about Linux.



I recently installed Ubuntu 13.04 x64 in my Samsung SF310 laptop.
Everything works fine except for wireless adapter.



I have been looking around for solutions and I must have tried everything I found, but with no success.



I can tell you that I have a Broadcom 4313 [14e4:4727] (rev 01) adapter. If you need/want more info on my system, tell me how to get it and I'll post it here. I have tried this with no success as well as virtually all other posts here.



If anyone could please help me and give me some pointers, that would be great.



Output of rfkill list all:

    Soft blocked: no

    Hard blocked: no

1: samsung-bluetooth: Bluetooth

    Soft blocked: no

    Hard blocked: no

2: hci0: Bluetooth

Output of lspci:

Output of lshw:

       capabilities: pm msi pciexpress bus_master cap_list

       configuration: latency=0

       resources: memory:f4c00000-f4c03fff


I'm getting really frustrated... It's been 3 days trying to figure this out without getting anywhere... Everytime I try a new version of Ubuntu (or any other distro for that matter), I always have some kind of problem... :(

This is a known bug, with a lot of duplicates.



I followed robamlers advice, and downgraded the driver to the previous version. It worked, at least for me.



Steps:




  1. Remove bcmwl-kernel-source version 6.20



    sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source


  2. I rebooted, just to make sure nothing remaining of the old driver. Not sure if this is necessary.


  3. Download and install bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64.deb from
    http://packages.ubuntu.com/quantal/amd64/bcmwl-kernel-source/download


  4. UPDATE: Ignore updates to bcmwl-kernel-source_6.20.155.1 untitl a new version comes available by writing:




    Package: bcmwl-kernel-source

    Pin: version 6.20.155.1+bdcom-0ubuntu6

    Pin-Priority: -1





to /etc/apt/preferences. (Courtesy of this answer)





More news: Upgrading to Ubuntu 13.10 Saucy Salamander will get you a warning about the 5.100 package, but the wireless interface still works quite fine.





Update: Now that bcmwl-kernel-source_6.30.223.141 is available, you can switch to the new driver.




  1. Remove pinning entry from /etc/apt/preferences


  2. Remove driver 5.100 version.



    sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source


  3. Install latest version from 'Software Center' -> 'Software Sources' -> 'Additional Drivers'.
