I have a Logitech M720 Triathlon connected (tried both with the reciever and bluetooth) and I have the same issue.
I can connect the mouse and it works for a while, then it starts to lag and disconnect after a few minutes. It will eventually connect but starts doing the same thing.
I have tried to repair/forget the device and tried multiple connections (has 1-3 memory positions for multiple devices).
Any thoughts on how to troubleshoot? I saw some old posts but they did not seem to do the trick.
Just to rule out the obvious first - is you mouse charged/has fresh batteries? Is your receiver connected to a dock that might have a bunch of other USB powered devices connected to it?
Yes, it is also paired to the MacBook Pro and works as expected.
Alright, a little bit of a face palm moment here…
I had rearranged the office and part of that was taking a part my desktop machine. I did not hook up the wireless antenna and as soon as I did the issue was resolved.
This was certainly a PEBKAC moment.
