WiFi and bluetooth adapter

WiFi and bluetooth adapter

Postby ChePeter09 » Sun Jul 21, 2019 5:38 pm

Good day.

I recently installed ZorinOS on my laptop. In the beginning, I could only use the Bluetooth adapter and I was able to use my Bluetooth mouse, but I couldn't use WiFi. After an update, now the System Settings says there is no Bluetooth adapter found and I still can't use WiFi. Please help.

I see you have an ethernet port on that report - can you use it to connect to the internet? If you haven't already installed it, install Synaptic Package Manager, open it and search for 'bluetooth'. If not installed, install:

blueman
bluetooth
bluez
bluez-cups
bluez-obexd
bluez-tests
bluez-tools
btscanner
gir1.2-gnomebluetooth-1.0
gnome-bluetooth
indicator-bluetooth
libbluetooth3
libgnome-bluetooth13

After installing do:

sudo apt-get update && sudo apt-get dist-upgrade.

Hi. Thanks for writing so soon.

I tried installing everything and then the update, but nothing. I tried rebooting as well, but it didn't work.

OK, try booting into advanced mode - if you can't see the GRUB menu at boot time, hold the left shift key while turning on. When you see GRUB choose the Advanced options then use the recovery option. Be sure you are connected via Ethernet. Firstly from the menu select the Network option, then use then select DPKG - this will check for any missing packages. After completion, turn off the notebook first then reboot - don't select continue. Keep us posted.

Hi.

I was able to go into the menu and did what you said, but I still can't use WiFi, nor Bluetooth.

I forgot to mention, when I click on the Bluetooth manager I get a message saying:

"Bluez daemon is not running, blueman-manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started"

I have this same exact problem on 12.4 Lite. I'm right there with you on this one, hoping for a cure. I eventually gave up on it and bought a USB OBDII connector.
