Did it ever happen to you, all of a sudden and without any warning or apparent reason, that your mouse starts lagging and stuttering and behaving completely crazy? It happened to me over the weekend (because this kind of problems seem to only happen when you have some extra time for yourself) and it drove me crazy: nothing seemed to make sense, the batteries of my wireless mouse were OK and everything else seemed fine. Still, my mouse was stuttering and lagging and ruining my day. So I decided to investigate, find a situation and I am now here to help you as well if you’re in the same corner as I am: here’s how to fix mouse stuttering and lagging in Windows 7, Windows 8 or Windows 10.

I think it goes without saying that the stuttering happens with my wireless mouse – and you probably have the same problem. The internet suggests a ton of fixes and I have tried them all, without any luck or improvements. The behavior of my mouse was also very strange: it would work perfectly fine for a short (or longer) period of time, without any jumping or stuttering, and then all of a sudden it started to lag and act all crazy. I was baffled to find out who was responsible for this and I wouldn’t have guessed it in a million years:

It was my Wireless Router!

I had my Wireless Router positioned right next to my computer and apparently it somehow decided to interfere with the signal my wireless mouse was sending, and this caused all the lagging and stuttering. It’s very easy to test if that’s your problem: just turn off your router and wait for a few seconds. If everything goes back to normal and your mouse works as it should, then this is it!

In order to fix your mouse problems in this case, all you have to do it move your Wireless Router at least 3 feet (1 meter) away from the computer. The more space you can get, the better! Or you can always get a classic wired mouse and keep your router there – but it’s usually a lot easier to just move the router away. This managed to miraculously solve my mouse stuttering and lagging problems and I am sure it will help you as well.

NOTE: Any other type of wireless device that’s near your mouse’s USB port might cause the same problems, not just a wireless router.

However, if this doesn’t work, make sure that you try other fixes for your problem:

– Make sure that your batteries are not empty or nearly empty. When they are, they can cause strange behavior from your mouse.


– Make sure that there are no problems with the USB port you have your mouse/wireless adapter plugged in: simply test your mouse on another computer/laptop and see if it works normally. If it does and none of the other fixes here seem to do the trick, it’s most likely that your USB port decided to go crazy.

– Clean up the sensor of your mouse (the shiny thing on its bottom): a small hair or dust particle could cause all the trouble, so make it a habit to constantly clean that.

– Make sure that the surface you’re using your mouse on is mouse friendly. If you’re not sure, the best thing would be to get a mouse pad and place it on a flat surface when using your mouse (your bed sheets are not considered a flat surface!)

– In Windows 7 and above, try turning off advanced visual settings like Aero, especially if your computer or laptop is an older model. In order to turn off the Aero Options, right click anywhere on your desktop and select “Personalize”. In the new window, choose any of the themes under the “Basic and High Contrast themes” and you’ve disabled Aero, which uses up quite a bit of resources and might be the cause for mouse stuttering and lagging.

But I personally believe that in most cases, it will be the Wireless Router interfering with the signal sent by your wireless mouse, and moving the Router farther away will fix your problem.
