I've been running Ubuntu 20.04 for a long time but recently bluetooth has been getting squirrely. I installed blueman and then it worked fine again. Today I rebooted and now it doesn't appear to recognize I have a bluetooth adapter at all. It is an Inspiron 15 3000 with a built in bluetooth adapter. When I run rfkill all I get is:
rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
No bluetooth.
When I run bluetoothctl
Waiting to connect to bluetoothd...
And then it just sits there.
When I run sudo lshw -c network

It is acting like the OS just stopped seeing the adapter altogether. Anybody know how to fix this? The hardware is only like 14 months old.
Thanks.
