However, the Bluetooth function become weird connect and disconnect randomly. Today it disappear in Win 10 device manager and not found anymore.
Please help, Bluetooth is important function for my board.

3. Please install the latest BT driver from below link.

4. Please check if the WiFi/BT card is installed properly, you will need to remove the metal from rear panel.

5. If possible, please change another Bluetooth device.


Thanks!

All the best,

I'm not sure which WiFi module your X370 Fatal1ty Pro came with. Maybe Intel AX200? They should all be compatible, so you could try a newer AX210. Intel models ending in 1 (e.g. AX211) won't work with AMD CPUs, so avoid those.

I rarely use WiFi from a desktop, so I pull them out from motherboards that come with one. Thanks to that, I have a collection of old WiFi/BT cards, and I've swapped them among computers before and they all seem to work fine. For example, X470 Fatal1ty ITX/ax came with an AX200, so I put that in a Framework 13 laptop.

The only unfortunate things is that you'll almost certainly have to take the motherboard out of the case to get to the two small screws at the bottom, in order to replace the WiFi card. Looks like X370 Fatal1ty Professional Gaming is even more complicated!

I found this website showing me how to replace the WiFi card. https://forum.level1techs.com/t/tutorial-asrock-x370-fatal1ty-professional-taichi-wi-fi-and-bluetooth-module-upgrade/162922 I also wanted to ask if there is a way to check if the WiFi card that is already in there is defective. Can I run a check through Windows that could tell me that the hardware is the problem and not the software? Last think I want is to find out that the WiFi card is perfectly fine and I got a new WiFi card for nothing and still have to live with this problem. :(

I also use a wired ethernet connection for the internet I just need to use the Bluetooth properly.
