Problem number one:
Wireless is not showing up. I can only see wired network and connect via Ethernet (I've tried unplugging)

Problem number two:
Bluetooth is "on" but my laptop isn't showing on my phone and my headphones aren't pairing either.

Thanks in advance for your help!

Wireless is not showing up. I can only see wired network and connect via Ethernet (I've tried unplugging)

sudo apt-get install broadcom-sta-dkms

That should do it, and it might also rectify the bluetooth issue.

I ran the command and I found the problem. Secure boot isn't configured properly and I can't type the password when I try to enrol MOK

Disable Secure boot in bios and post results for

Code: Select all

dmesg | egrep -i 'blue|firm'

[m10571]

After disabling secure boot wirless works but bluetooth still doesn't.
I don't know if this is relevant but in the bios the 'password on startup' was empty.
