There are no hardware information or system logs attached so one can only guess what's going on; however there were reports that disabling fast startup in Windows is required for wifi and/or bluetooth to work properly. Please give it a try.
I did a quick search and a tutorial shows how to disable it https://help.uaudio.com/hc/en-us/articles/213195423-How-To-Disable-Fast- Startup-in-Windows-10 ** Summary changed: - Bluetooth is not working in Ubuntu 20.04 + Bluetooth is not working in Ubuntu 20.04 (dual boot Windows) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937872 Title: Bluetooth is not working in Ubuntu 20.04 (dual boot Windows) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1937872/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
