I have been trying to connect to my wireless network for weeks, tried a bunch of new and legacy open source and Broadcom STA-proprietary drivers for BCM4311 (103c:1371, wl) without the option to connect in the menu, "blue" led-indicator not working at all and I'm not able to connect.

I've been trying to connect for weeks, tried all of the suggested solutions, all in vain: Broadcom B43 WiFi not working in Ubuntu 14.04 LTS https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

Operating system: Ubuntu 14.04.1 LTS (32-bits) with all the latest updates installed (Linux 3.13.0-44-generic)

If I were to install Windows 7 it would work flawlessly, but I rather not walk down that road again, it's one of the main reasons I chose Ubuntu 14.04 over Windows 8 and their stupid "modern"-UI.

Please obtain a temporary internet connection and open a terminal:

sudo apt-get update
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Reboot and tell us if the wireless is working as expected.

If the wireless switch is not working, please try:

sudo modprobe -r hp-wmi
rfkill unblock all
rfkill list all

Any improvement? If so, we will blacklist the module.

Please see this bug report about the same laptop and the same problem: https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/183548

Thanks Erin,the reset to default bios settings worked for me too!

  • I tried that, but it's still the same, unable to connect, grayed out in all menus (can't turn it on) and no blue led-indicator. I rather not be forced to revert back to Windows 7 unless there isn't anything more I can do about it that might help? – Mathias Jan 30 '15 at 22:29
  • May we please see the diagnostic as described here? http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos/425180#425180 – chili555 Jan 30 '15 at 22:42
  • I ran your script and saved my report http://pastebin.com/XbjVDTvM – Mathias Feb 01 '15 at 23:01
  • Your wireless shows as "Hard blocked: yes," suggesting that you should find and switch the hardware wireless switch or key combination. It may be #18 here: http://www.server-unit.ru/tekhopisaniya/files/12684_OV.gif – chili555 Feb 02 '15 at 00:20
  • I've tried to enable the wireless network adapter numerous times before without effect http://youtu.be/cSg3Q5r9Ecw that's the "blue led-indicator" i was referring to earlier and here's another picture from within Ubuntu https://i.imgur.com/UNdQfO3.jpg this happens whenever I try to active the adapter (from within) it jumps back and remains being grayed out. – Mathias Feb 02 '15 at 01:52
  • Please see my edit above in a few moments. – chili555 Feb 02 '15 at 02:25
  • That did unfortunately not solve my problem, it says "soft blocked: no" and "hard blocked: yes". – Mathias Feb 02 '15 at 16:33
  • Which did not solve your problem? Removing the hp-wmi module or resetting your BIOS to defaults? Or both? – chili555 Feb 02 '15 at 16:49
  • I tried fiddling with the "lan/wlan switching" and power saving options in the bios earlier, with no effect, restarted my computer once more to double check, enter the bios menu (only this time I chose to "restore defaults") logged into Ubuntu, blue-led wifi-indicator starts flashing, wireless network tab isn't grayed out as before and I'm able to successfully pick my wireless network and connect! Thank you so much for all of your hard work and support! – Mathias Feb 02 '15 at 18:45
