1.5 - 2 meters is between 55 inches to 80 inches. That is a LONG way away to be using a mouse on a notebook computer.
I suggest you get a Wired USB mouse and a USB extension cable.
Sure something plugged into a port right next to a USB receiver willl affect how that receiver picks up the signal from the other end.
So move closer to your computer.
