Mac mini - Wifi - Juddering mouse

[Macs4u]

Hi,

I have a Mac mini Late 2012 i7 2.3ghz with 512Gb SSD and 16GB Ram. The problem I have is this..

When I switch my Wifi pn, the Logitech wireless mouse judders. When I switch the wifi off and connect via ethernet the problem goes away. What could cause this?

Also when I tried adding a 4 port USB 3.0 hub, the mouse juddered too. (although can't remember if I was connected to wifi at the time)

Any ideas?

Matt

There's a thread about macOS Sierra interfering with Logitech mice. Is yours affected by this?
