Aspire 5 A515-51G-54G6 bluetooth problem

newzeland3 · April 2018

Hi,
While I was using bluetooth connected wireless speaker, connection has gone and I saw information "Bluetooth function is off". I can't turn it back on. I can't even see bluetooth in device manager. It looks like software problem. Can someone help me, please. I have read many people have the same problem.
Thx

>>>can't even see bluetooth in device manager>>>

So Microsoft must've been trying to hide it from you!

You have to go "Ansicht" and press "Ausgeblendete Geräte Anzeigen".
After this just "deactivate" the Unknown USB-Controller and "activate" it again.

Hello,

I fixed this problem with refreshing of Wi-Fi driver. Download and install this or newer driver:
