5] Check for interference issues

WiFi signals have two different frequencies, 2.4 GHz and 5 GHz. If your computer is connected to a 2.4 GHz WiFi band, you may experience issues with the Bluetooth network because of interference. The reason for this is the same frequency of these two technologies. Bluetooth networks work on 2.4 GHz. If the WiFi signal uses the same band, interference issues may occur.

To fix this, switch your WiFi band from 2.4 GHz to 5 GHz and then connect your device to the computer via Bluetooth. Once you switch, your Bluetooth network issue should be fixed.
