I just upgraded my Samsung NC10 netbook with Broadcom BCM 3411 WLAN to 14.04.

I'm not seeing any wireless connection choice under Network Manager, but it connects just fine on ethernet.

Ubuntu newbie, so may be missing something obvious.

Ran rfkill list all:

sudo rfkill list all 
0: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no
1: samsung-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Also ran lshw -class network:

sudo lshw -class network
  *-network

All assistance much appreciated! Thanks!

  • Not sure if this will work with 14.04, but you may want to check out Samsung tools, as referred to here... it's possible that your device doesn't actually have WiFi toggled on... linuxg.net/…

Please do with an iternet connection:

sudo apt-get purge --remove bcmwl-kernel-source
sudo apt-get update
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

wireless should now be working.

Try running Additional Drivers and see if an option comes up for your Broadcom wireless driver. Failing that try holding Fn and tapping F9 as this should toggle the wireless on and off (watch for an LED status change) See page 87 of the manual you'll note that the wifi is an option that may or may not be installed. If not you may need to acquire a USB wifi adaptor

  • Thanks, I did try that, but no available drivers came up. However I did find this post, help.ubuntu.com/community/WifiDocs/Driver/…12.10.28Quantal_Quetzal.29-1, and updated B43 drivers as suggested, but still seeing no difference. I still think there may be something simpla that I am missing here...

  • @user277954 as Kendor said "it's possible that your device doesn't actually have WiFi toggled on.." Lasptops often have a swirch or Fn key to toggle the state of wifi and a led to indicate status. researching your model

  • Your Bluetooth is Broadcom, Your wireless is Atheros provided your true model number is NP-NC10
