I've got a fairly new PC but when moving the mouse across the screen, the pointer jerks as if the PC is freezing momentarily every second or so. Strangely, this only seems to happen if the signal from the wifi router is bad. If I move the PC closer to the router to get a full signal, it's fine. It also seems to affect the keyboard; Opening notepad and holding down a key shows the same momentary freezes. -- Update: It's a logitech wireless mouse, and a wired USB logitech keyboard.

I've seen this issue with my wireless mouse, as it is in a similar frequency range to wifi - I resolved the issue by moving my wireless mouse dongle further away from the wifi antenna at the rear of my PC. I'm confused as to why a wired keyboard would suffer the same fate though... something you'll have to come back to if this resolves the wireless mouse issue I guess?! | |||

It's probably related to the networking and networking drivers in windows. I've noticed that on some machines when windows is busy with the network it can affect the mouse and launching apps as well. Everything becomes jerky. Make sure you have the very latest wireless networking drivers and ensure you've done a windows update as well and see whether that helps. | |||||

Go into Device Manager and turn the transmitter power down on your wireless adapter from "Highest"(default) to "Lowest". | ||||
