How to change bluetooth frequency for magic mouse 2 Sometimes my Magic Mouse does not work when Wi-Fi is on!
When I turn Wi-Fi off, I can move it again!
MacBook freezes frequently and it really drives me crazy! I guess it isrelated to the Wi-Fi, because when I turn Wi-Fi off, MacBook works better.


MacBook 2019 - Mojave 10.14.6

I read this question about Logitech mouse.  But I use magic mouse 2, not other brands.

I read this Apple Discussions article. My modem frequency is 2.4 GHz too. and unfortunately, it supports  only this frequency. 

Can I change Bluetooth frequency from 2.4 GHz to something else?
The short answer is no.

The 2.4 GHz frequency is what bluetooth uses so you would need to move to a place with less interference, turn off the conflicting devices to keep using Bluetooth reliably.

There are other frequencies mice, but Apple doesn’t make them. Look at Microsoft or Logitech if you don’t know where to start with mice that have a USB receiver and use other radio frequencies.


  Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second


So, if you have interference bad enough that BlueTooth can’t accomodate or negotiate a channel, something is really wrong. I would focus on software updates, resetting devices, turning off WiFi for 30 minutes to be sure you really have an interference problem
