About a week ago my bluetooth connection dropped. I looked in Windows 10 and it did not show up. I tried reloading driver but it did not help. I though maybe installing Windows 11 might make a difference but now neither the bluetooth or wifi work.  I downloaded the latest bios firmware from Dell and the problem was solved but every time I shut down and restart the bluetooth is gone and the wifi may or may not work.  I can re-install the bios firmware and everything works.  All drivers are up to date. 7386 2in1
