How to reduce effects of interference from other wireless devices
To minimize interference between your wireless network and Bluetooth devices, try the following:
Change channels on your wireless network. For Wi-Fi base stations, reset the base station and it will attempt to use the 2.4 and 5GHz channels with the least interference when it starts up.
Connect to a 5GHz wireless network (if possible).
Minimize the number of active Bluetooth wireless devices you have connected to the computer or operating in the area.
