Here are possible solutions:
① Please turn off the PC , unplug the power supply, and press the CMOS button (poke the hole of CMOS with a pin) for about 10 seconds , restart the PC after ten minutes.
②Please go to device manager to see if the ethernet driver has yellow exclamation ,if so , you need to update the driver.
③ Please right click windows--computer management--service and applications---services-- find and right click "wired auto config" ,start it.
Humm this happened to me tried for a couple of hours yesterday to uninstall reinstall etc. but to no avail, unplugged it for a couple of hour to start looking today. Plugged in wifi & bluetooth started up normally
Intel driver updater has given me a new driver to install which I have and working fine so far:
20.100.10.10 upto 22.220.1.1
Well, it's hard to believe, but it's true. In the Device Manager window, Bluetooth was only found when viewing the hidden devices area. After trying everything I know I could not get Bluetooth to work. After reading this post I shut down the computer and unplugged it for 30 minutes. Plugged in and started up the beelink and bang there it was. And now Bluetooth can also be seen in the regular view in Device Manager. Thanks for the assistance.
But serious people, there must be a better fix than unplugging the computer constantly.
