Question Bluetooth - Range dropped significantly

[sblue]

Hi-

The title states the issue - Bluetooth range dropping to about 20-50cm before having stable connection.

I perceive the experience when connecting a bluetooth speaker to the PC.
Previously I have had no issue connecting blue devices to the PC.

I have tried connecting multiple speakers with the same result - They need to be 20-50cm within the PC before they can connect and play music with a stable connection.
I am on Windows 10 Home 64bit
CPU: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz 3.60 GHz
GPU: RTX 2060
Bluetooth 5.0: Intel(R) Wireless Bluetooth(R)
Motherboard: ROG MAXIMUS XI HERO (WI-FI) - Intel Z390 ATX

See your mobo manual, p. 2-14 regarding the antenna module for BOTH WiFi and Bluetooth. Check that both cables of that are plugged into the two rear ports and securely tightened. Then ensure that the antenna module is placed in a clear spot with no junk around it to interfere with its radio signals.
