Hey Mate!

It sounds like it’s as simple as your mouse and your wifi access point are putting out the same signal and your computer is getting confused and mixing up the two. Image there's one remote controlled car (your computer) with two controllers that are telling it to do different things (your wifi and your mouse). 

I would suggest switching your wifi channel to either channel 6 or channel 1, this should move it away form the mouse channels and see if it changes anything. Here is a link to help you out:

Let me know how you go!

Same here. Switching channels on router does not help. I wonder why Razor Support do not react on this questions. There are several threads on this issue.
