After I updated my my ubuntu 16.04 yesterday I have not been able to turn on my bluetooth. So I went ahead and searched the net and tried to turn it on (the icon was also missing from the menu bar).

I have tried this 

sudo apt-get install blueman bluez:i386 bluetooth

I have also tried this 

sudo /etc/init.d/bluetooth start

and this too 

gksudo gedit /etc/rc.local

and I have pasted this rfkill unblock bluetooth before exit 0.

Somehow I managed to get the bluetooth icon but I am still not able to turn on my bluetooth.

Here is the output of lspci

EDIT : output of lspci -nnk | grep -A2 Network

  • @Pilot6 This was all working fine untill I updated softwares – lord_ozb Nov 17 '16 at 11:42
  • Since the driver needs to be built for every new kernel, you'll need to rebuild it after every kernel upgrade – unless someone creates a DKMS package for it that automates the build. – David Foerster Nov 21 '16 at 09:45
  • @DavidFoerster Last night when I turned on my Laptop the bluetooth was working fine but when today I turned it on again the same problem. – lord_ozb Nov 22 '16 at 04:29
  • Did you boot to a different kernel? What's the output of lspci -nnk | grep -A2 Network? – David Foerster Nov 22 '16 at 12:33
  • @DavidFoerster No, I booted in the same kernal. Output: Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01) Subsystem: Hewlett-Packard Company BCM43142 802.11b/g/n[103c:804a] Kernel driver in use: wl – lord_ozb Nov 22 '16 at 12:38
  • Could you please [edit] your post, when you want to add information? Especially file or program output listings (with the help of the {} button in the editor toolbar) will be much more readable there; alternatively you can use a pastie service for longer listings and include the link of your pastie in your question. Overall it’s best to have everything relevant in one place. Additionally, comments may be deleted for various reasons. Thanks. – David Foerster Nov 22 '16 at 12:41
  • wl is by far not the most appropriate driver for BCM43* chipsets. Could you please consult https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers and see if that improves the situation? – David Foerster Nov 22 '16 at 12:42
