I have been using the Logi MX Master mice for a number of years now without any issue. It was after a major Win10 update that problems emerged--the sticking and erratic movements. Oddly, it seemed to come and go. Changes to Logi Unifying software, driver updates, so on, and so forth did nothing to change the behavior. I then found this article and moved the receiver to an empty port on the side of one of my Asus ProArt monitors--a good five feet away from the tower case. Problem solved! Thank you for posting this fix!

After replacing my win7 desktop with a new high-power win10, my Logitech K350 keyboard as well as my M510 mouse have been behaving erratically despite a variety of attempts to remediate. A 4 foot USB extender cord now places the receiver away from my desktop and about a foot past my keyboard and mouse. Both work perfectly now. Thank you so much for the solution.


Hello everyone! Thanks for this post. I wanted to share that I had this issue with a Logitech M510, erratic cursor, would drop connection, etc. I switched the batteries from almost dead Kodak AAs to charged (I believe fake) Eneloop Pro AAs, the issue persisted. I unpaired and re-paired the mouse and nothing.
Then I decided to use a brand new se of IKEA AAs made in Belgium and the mouse now works great!!!
So the quality of the battery should be something to inspect IMHO, the fake Eneloops were even heating up inside the mouse! I know my apple wireless keyboard doesn't even accept them so there you go... picky electronics.
Hopes this helps


I wouldn't have believed it if I hadn't tried it myself. My trusty M705 which I have had for years, started doing the erratic jumpy thing. I tried everything before I googled it and presto I found this blog. Works like a champ now

I came to the same conclusion for awhile as it seemed to fix my issue, but recently it resurfaced. Erratic cursor movements, bad tracking of the buttons, etc. I needed to be real close to the receiver for it to somewhat work. This time I tried another receiver I had, repaired everything (I have an MX mouse and a keyboard), and all is good. So I come to the conclusion that the Unifying receiver can fail in a slow manner over time. Using a usb extension can alleviate the symptoms for a while, but if it degenerate again, you may have to change the receiver.

Using the USB Extension lead solved the problem brilliantly... Someone at Microsoft should look at this solution instead of the BS answers they continually provide. I had tried every solution they proposed short of rebuilding my system none of which worked of course.

Thank you for a simple but effective and very logical answer


Look for dirt or lint in the optics - I had a small hair near the lens causing chaos.

Thank you so much for ending hours of frustration trying other solutions that I found online.

A million thanks!!!!! changed to the back USB and this works excellent! I F'ed around with this for 6 months! http://oppjunk.com


This article made me do a double check on the nano receiver, and notice it was plugged in right next to a wifi nano-dongle. After moving them apart, the problem was gone.


I have the K850 keyboard that came with the M720 mouse. My mouse would slip away from the word document that I was moving to another location on my screen by sliding it across. The mouse would drop the word document and as I was sliding it would start dragging whatever was in the way (other folders in its path). Luckily I had another new Keyboard and M720 mouse. The new mouse with the new receiver fixed my problem. I can guess that maybe the receiver was failing, but since I replaced the mouse and the receiver I will have to later put back the old receiver on the new mouse and see if the problem comes back. I hope this will help the community with this problem and later I can add to this post. Thanks for sharing your info on your similar problems.

So useful, this saved my expensive purchase!!! My sensor does not like to work on the back of a printed A4 paper but works wonders on the flap of my 2nd laptop!! I will now get a proper mousepad and see. Thanks article for inspiring!

Thank you thank you thank you. You have saved my marriage of 51 years. My wife's Lenovo all-in-one computer just started doing this about 3 weeks ago, albeit on an intermittent basis. Prior to tonight I had solved it by unplugging and re-plugging the unifying receiver from one usb port to another (note all the ports are on the back of the huge monitor which also houses the hard drive, motherboard and other assorted electronic beasties). Then I found this post and Ta-Da, it worked a charm. Mr. Ralph Grabowski, you are a god among men. My wife thanks you, I thank you and my dog thanks you. If you were my next door neighbor, I'd make a couple dozen pierogis and come knocking on your door with them and a six pack of your favorite beer. Thanks again for your wonderful post. -John


I added a USB extender years ago and solved the problem. Then the problem came back! The cure was a longer USB extender cable and now the nano is just one foot away from the mouse.


Dude - you are a helpful guy - thanks!


Almost 7 years later and this is still a brilliant solution to my problem. Thanks! My mouse works perfectly now. But it's really bad that the logitech reciever is so weak.
