Seems to be a specifiic DELL issue, I had this a while ago and turned off BlueTooth on my laptop since I didn't use it anyways. Then forgot about it.
Question for the future, is this a BlueTooth/WiFi 18,04 driver issue or a udev issue you think? :-S
Note : I'll get back to this forum if I come accross it again. - Bookmarked
