I have an issue where my bluetooth randomly cuts out, like so:

Screenshot_Of_Settings_Menu

I have read some existing Ask Ubuntu posts on this issue.

I followed this post: Bluetooth randomly cutting out in Ubuntu

and ran sudo apt install -y linux-oem and restarted my computer, but I'm still having the error.

I also looked at this post "No Bluetooth found Plug in a dongle to use Bluetooth"

but the output of rfkill list all was:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

What other fixes are there to this problem?

First, run this command for switching on devices

hcitool dev

After that run this

sudo systemctl restart bluetooth

for checking status of your, Bluetooth run this

systemctl status bluetooth

    Did not completely fix the issue for me, but at least it helped me get closer as i now have a non-dead output returned from systemctl status for the bluetooth.service.

You can simply try to perform a cold reboot. It worked in my case.

My Bluetooth disappeared in both Ubuntu and Windows after turning it off in Uubuntu. I was never able to turn it back on from either OSs. Aman Singh's answer did exactly what @peter-krauss says in the comment to that answer.

What did work for me was 1) From the BIOS turn off the WiFi adapter (which controls both Bluetooth and Wifi in my system), 2) Reboot and 3) Turn it back in the BIOS again.

Again, somewhat lame answer but mine is working.

Besides trying all suggestions out there, the only thing that really fixed the issue for me was to update my BIOS to the most recent version.

Essentially follow the following steps:

  1. Download the BIOS from your hardware provider[Intel in my case]. Save it onto a USB drive.
  2. Reboot your machine and and press F7 during boot. This key might be different based on your hardware.
  3. Select the bios file you'd downloaded and let the bios upgrade. On reboot your Bluetooth should be back and functional.

Try this in the command line and perform a system restart.

sudo add-apt-repository ppa:bluetooth/bluez
sudo apt install bluez
