I am using Ubuntu 14.04 on my HP laptop and I do not have any wireless connection.

I have followed the procedure given on this post My wireless/WiFi connection does not work. What information is needed to diagnose the issue?, and I give here the generated file: http://paste.ubuntu.com/10901227/.

Can anyone help me fixing this issue?

Regards, Xavier

  • Have you disabled all your wireless? without the data in the diagnostic information we can not see how it is trying to work. – grantbow Apr 26 '15 at 18:49
  • sudo modprobe wl and see if it works and it appears that you are just trying Ubuntu from the installation media – Jeremy31 Apr 26 '15 at 19:18
  • Thanks for your answers. GrantBowman: My wireless is activated. It works OK when using Windows. Jeremy31: With this command I get the following: modprobe: FATAL: Module wl not found. –  Apr 26 '15 at 20:27
  • @Jeremy31: I forgot to react about one of your remark. I am indeed trying Ubuntu from a stick. It is then not installed on my laptop at the moment. Do you think this has an influence on the issue? –  Apr 26 '15 at 20:46
  • Have you rebooted since running the wireless script? If so you need to go into software and updates/Additional Drivers and select the broadcom STA driver to install – Jeremy31 Apr 26 '15 at 20:52
  • Yes I have rebooted. In the tab you indicated me, I have chosen the Broadcom STA, then I clicked . I was connected through eterneth while doing so. Nothing new apparently, my wireless is still not working. –  Apr 26 '15 at 21:03
  • @GrantBowman: I have typed ifconfig -a on a terminal, and I get only two entries: eth0 and lo. With the command nm-tool, the only device that appears is eth0. I am not sure whether these can help. –  Apr 26 '15 at 21:10
  • Since you have ethernet available sudo apt-get install bcmwl-kernel-source and see if the wifi will work – Jeremy31 Apr 26 '15 at 21:17
  • I had the following: http://paste.ubuntu.com/10903014/. Wifi is still not working unfortunately. –  Apr 26 '15 at 21:22
  • dpkg -l | grep bcmwl But it is likely a false hope – Jeremy31 Apr 26 '15 at 21:27
  • Here is the result: http://paste.ubuntu.com/10903073/. –  Apr 26 '15 at 21:31

Download the bcmwl-kernel-source from a mirror site from here and install

For some reason Ubuntu decided to put a 3.16 kernel with a version of bcmwl that doesn't work 6.30.223.141 as it does't have the needed patch

If the answer works, please file a bug report, info here

  • Thanks a lot for your help. This settled the issue, my wireless connection is now working. –  Apr 27 '15 at 12:03
  • I am not familiar with bug reporting. I have followed the instruction given on https://help.ubuntu.com/community/ReportingBugs. When typing ubuntu-bug bcmwl-kernel-source on a terminal, it is said that the problem cannot be reported as it is not an official Ubuntu package.

    I did not find how to proceed. Can you help me with this?

  • I would file against Ubuntu if possible as it was their mistake mixing a kernel with a package that isn't compatible – Jeremy31 Apr 27 '15 at 14:44
  • Ok, I will try to find a way to open a new post in order to report this bug. Thanks again. –  Apr 27 '15 at 17:20
  • I downloaded the ISO and filed my own bug report here You can click "This bug affects me" and there was a bug report over a month ago here – Jeremy31 Apr 28 '15 at 09:42
  • Thanks for taking care of it and for the information.

    I am surprised: when I click on "Report a bug" via the URL here, I end up there. I was trying to find the way to fill a report following the indication on this webpage yesterday, but at the end I was not able to find something.

    On the contrary, when I click on "Report a bug" on your page here for instance, I can start filling a report easily.
