    Question Ubuntu 20.04 LTS, Realtek R8822BE Bluetooth Stopped Working

    Okay so I am at a loss here. I have Googled this to death, searched more forums than I ever knew existed, and still cannot figure this out. I am hoping I am just missing something super obvious...

    So I have an ASUS laptop with a Realtek R8822BE Wi-Fi/Bluetooth card. I installed Ubuntu 20.04 LTS about 2-3 weeks ago and everything has been working amazing. Then today, I ran out to get lunch and when I got back the icon for Bluetooth showed like it was off (even though in the drop down turning it on was not an option). I rebooted and when it came back up, under Settings->Bluetooth shows no bluetooth installed. I have installed anything other than system and software updates that I get prompted for. I have not messed with any of the settings or config files for Bluetooth. And nothing seems to bring it back. Any suggestions are greatly appreciated, and please let me know what (if any) I can post to help in figuring this out. Thanks in advance!

    Blessings,

    It seems like it is working again, and the Wi-Fi was acting up for a few minutes, but now everything seems okay again...I think...but here is the info you asked for. Thank you for any help you can offer.
