When the cursor gets erratic, it's the mouse's nano-receiver at fault

It's common nowadays for wireless mice to be packaged with a nano-receiver, a tiny receiver the size of a small finger nail, that plugs into a USB port.

On two systems, I've experienced erratic cursor behavior as I move the mouse. The cursor jumps or sometimes doesn't react at all. 

The problem is due to the receiver being too close to the USB port. It picks up electronic noise generated by the computer's parts, interfering with the signals passing from the mouse. In addition, I found the problem specific to Logitech's Unifying receiver, which handles up to six devices. I suspect that there is just too much tiny electronics crammed  into the tiny chunk of plastic and metal.

The solution is to install an extender, a male-female USB cord. It moves the receiver away from the computer. Even a couple of inches helps, but in severe cases, you may need to use a longer cord.

This solution worked for me.

Unfortunately I discovered this same solution by trial and error and many frustrating hours.

I had a Logitech MX Master mouse with unifying receiver mated to a desktop USB port.
Suddenly out of the blue.. the mouse was not tracking properly anymore.. then it failed to track at all.
Windows 10 reported no problems with the device in Device Manager.

I plugged the Unifying receiver into a different computer and got the same erratic behavior in just a few minutes time.
I had switched ports on both computers, avoided USB 3.0 ports, made sure no other USB devices were plugged in, yet the problem persisted. Even with a different Logitech mouse, confirming it was the receiver and not the mouse.

Upon disconnecting other USB devices I decided to use the USB extender for my WIFI Dongle with the Logitech Unifying receiver. The mouse started working properly again. I tried it with the MX Master mouse and that also worked fine so long as the receiver was not plugged directly into the USB port.

I admit that having to use a USB extender cord defeats the clean look of a hidden nano device, but if a simple cord breaths new life into $100 mouse that is only 3 months old, then I can live with the slight inconvenience.

I wonder if laptops have more shielding than desktops, and so the nano-receiver works well with laptops, fooling us into thinking that it should work just as well as desktop computers.

[David]

Thanks ... so much
It worked for me with an MX logitec that was making me waste my time keeping the cursor going where I wanted....

[Stanley]

Unfortunately that didn't work out for me. A simple trick by disabling trackpad while mouse is connected actually works. Thanks to Andreas who wrote in this article: http://www.anysoftwaretools.com/fix-mac-cursor-trackpad-problem/

By the way, I'm on a Mac.

[Jarrett]

This worked for me. The mouse had problems whether using the front or rear USB port on the tower. As soon as I moved it to a USB extender cable, the problem was solved.

[Marlon]

It worked! Thanks!!

[Vidmon]

I've been using the MX mouse for about 2 years without any problems. Then all of a sudden the Sh-- hit the fan while trying to edit photos in PS and moving files in Explorer became a copy and paste adventure often wondering where they would end up. Click & Drag became a nightmare and the simple task of cropping photos in Photoshop became an editors nightmare. I moved the receiver from one USB port to another one and it helped with certain tasks but not the critical ones like adjusting the photo levels in PS. I switched out the battery that came with the MX to a higher amp battery and that didn't help either. I uninstalled and reinstalled the MX drivers and that didn't help either. Finally I went back to my wired mouse and everything got back to normal. I paid a lot for the MX mouse and expected a lot in return. I own several Logitech products and they all work great so I'm guessing I got a lemon but for now my wired mouse is working great.

[Ralph Grabowski]

I continue to use the MX mouse, replacing it as it wears out every couple of years. I use a short USB cable extender to keep the receiver away from my desktop computer's case. Ironically, I keep it tethered to a thin USB cable, to keep the wireless mouse charged.

[dave]

Did the trick on a small barebones cube build...thanks much!!

[roy]

oh it worked for me! Been annoyed with this for months.

[William]

If wireless try moving it further away and maybe trying a different mouse pad underlay.

[Polyrus]

Many thanx for the original post. I don't have a cordless rodent and use a wired G500s but had the same symptoms. as soon as I connected it via a USB extender cord my problem was solved!

[David]

logitech wireless mouse works fine when plugged directly into my laptop hp250g4 using win 10 64bit os when moved to a add on 4 usb device it will not work using seagate 2tb hard drive working ok

[Steve]

My best solution was to ditch wireless mice and return to a good quality gaming mouse with a cord - PERFECT

[Paul]

This has been driving me crazy for months.I had an old USB extension cord lying around and ran across your post. So far so good. Thanks!

[Terry L Mundy]

Worked for me! Like Paul said, it's been driving me nutty. Thanks for explaining why it works instead of that "it just works".

[steve]

I had the same issue with a Bluetooth dongle.a slight turn of the head and my blutooth headphones would lose connection.i plugged the dongle into a usb extension cable(after reading this post)and bingo.its perfect.saved me a few quid as I was going to but a Bluetooth pci card.thanks

[Speedmaster]

If you have a cell phone near to your wireless receiver move it far from the receiver. I had two cells near it and it was a nightmare...not only the mx mouse was horrible but also the keyboard. Moving the cell solved all the issues... As we can deprehend the problem is related to interference....

[Brian]

Moving the nano receiver worked for me.

Thanks very much for the hint

[Tahlskog]

well usually people plug their unifying receiver in at the back of the computer, and your mouse is usually in front of the computer. and most often people have their computers under their desk. Your computer case being usually one large piece of metal which is hopefully grounded too, this causes radio signals to not pass through at all. and as such it is impossible for the wireless signal to get a clear path to your mouse, your mouse essentially stays in radio shadow. radio signals don't really bounce around much in your average house/apartment.

So putting an extender cord on the unifying receiver and extending it outside of the case so it gets a clear path to the mouse, should indeed help alot. Most non-metallic surfaces do not interfere, only if they are very thick, or contain a lot of water.

[Tom Keffer]

Plugging my receiver into an external USB hub worked for me.

Thanks for the tip!

[Bill Brown]

Thank you! Extending the receiver (Microsoft wireless mouse) away from the USB connections worked. This has been driving me crazy!

[Michael Rossiter]

Brilliant! Worked for me also. Use a HP laptop but in the home office it is connected to a Logitech K800 keyboard and Performance MX mouse with a single Unifying receiver; all was well until I had to replace the Samsung monitor and that's when the problem started! Searched all over various forums; updated drivers, changed the USB port the receiver was plugged in to, etc., etc., then came across this post and once the receiver was moved away from the laptop (just by a few inches) all was well. Not sure why changing the monitor lead to the problem; perhaps because it is now connected via a display port not HDMI but following the advice above the problem has been resolved. Thanks for the tip.

[Janet Hudgins]

I have a Mac and tried most of these comments without success. It doesn't seem to be a brand, just Wireless Mouse, made in China and I've used it for about a year with no problems until recently. I'm using an old wireless mouse and keyboard now with no problems. But I prefer the one that's gone wild as it's smaller and the mouse turns itself off. I tried changing from the USB extension directly to the MacMini but it didn't help. And the Trackpad is not connected, I've set the Mouse at a little slower and I'm not using the Natural direction.

[Ralph Grabowski]

Today's mice from Logitech last a long time on a battery.

I recommend against the ones with rechargeable batteries:

They do not run as long as chargeable ones
They need to be plugged in, so you are back to have a corded mouse
You have to hunt down replacement rechargeable batteries, which cost
a lot more than regular batterers bought in buld.

[Garry Jackson]

Worked for me. Thanks a lot.

[Tracy]

I thought I was going to lose my mind trying to find a solution. I gave up hope of fixing my wireless mouse lag/freeze after trying all the troubleshooting suggestions I could find. I plugged in a wired mouse and it worked. I then gave trying to fix the wireless mouse issue one more try, and came across this post. Using a USB extender cord really works!!!

[Brandon]

Wow - Every 2 years I been just buying a new nano receiver assuming that was the life expectancy.

Moved receiver from rear to front and appears I might get just a little more life out of it...

[Julian]

Someone comments that usually USB ports are at the back of computers and computers are sometimes under the desk. I had problems with my mouse that were solved moving the nano receiver to the USB ports at the monitor. Nowadays many monitors have USB ports. Maybe the ones who want a clean desktop can try it.

[Ed]

I had the same problem when the receiver was directly inserted into a docking port (on a cord) where it became hot. It didn't get hot when directly connected to the laptop. So I connected it to an extension cord to the docking station, now it works OK, so far.

[Robert]

I had to install a USB 3.0 to Ethernet Adapter after a Lightning storm took out my regular network adapter. Afterwards my mouse started acting up. At first I didn't relate the two. I then just moved the mouse receiver about 12 inches away from the USB to Ethernet adapter and it fixed my mouse problem

[Whitney Dodman]

This totally worked for me. I used an extension for USB and the stuttering cleared up right away.

[sean]

i just tried one of the comments that mentioned using a different mouse pad... i took the black mouse pad away.. my logitech mx anywhere mouse is working much better now.. jeez... not perfect.. it was so glitchy removed the pad now its working better.. lol

[silversurfer60]

I have been going nuts with this problem since I upgraded to Windows 10, having bought a new laptop. I often wished I could go back to good old Windows 7. I am going to try my mouse with the seemingly problematic Unifying Nano Receiver in an extension, which I'll get from Ebay so hopefully, I won't be untangling half a sentence I type in 'Word'. I write a lot of fanfiction and it takes twice as long when the stupid cursor jumps back halfway up the page or worse still, decides to minimise the program or do something stupid. Fingers crossed it works when I get the extension.

[Ralph Grabowski]

I have updated computers that are not critical to my business to Windows 10, so get the "free" operating system.

But computers critical to my business stay on Windows 7, for the simple reason that some of the softeare I use to make me efficient at my work do not work on Windows 10 (or even on Windows 8). It makes no sense to "update" when the result is a downgrade..

[Danny Crawford]

Wow!! I was preparing to have to re-install drivers or even purchase a new mouse. I tried this fix and so far it is working great!! Thanks for sharing this!

[Andrew Crowe]

Perfect thanks.

Worked a treat on a new Macbook pro with Mojave and external logitech mouse

[Heather M]

Thank you so much! This article and the fix recommended worked like a charm and saved me from the insanity of trying to figure out why my brand new Logitech M525 mouse suddenly stopped working correctly. Thankfully I already had one of those extender cables and fixed the problem seconds after reading the article.

[A Evans]

I've run into lag/stutter issues even with an extender, if my nano-receiver is touching the monitor cable. Luckily the fix is simple, move the monitor cable away from the receiver+extender.

[bob]

Ahhh!! you solved a very frustrating issue I've had with both mouse and keyboard!!! it would work fine for months then mysteriously drop keys and mouse clicks. A 6" extension resolved it. THANK YOU!

[ahart]

Great post Thanks! After reading I Added a 4 port USB extender with it's 6 inch pigtail going to the PC. Problem solved! Also verified, as others noted, that a cellphone near the wireless mouse can cause jumpy mouse behavior.

[Pete]

Had exactly the same issue with a Logitech MX Performance mouse that is around 5 years or so old. The receiver was plugged into a USB 2 port on the back of the computer. All of a sudden, it stopped tracking properly causing huge frustration. I reinstalled the Logitech drivers but the issue persisted. I plugged in a standard USB mouse and that worked correctly. I have a 7-port USB 3 hub on my desk so unplugged the receiver and put it into the hub; the mouse is tracking perfectly again so this is a great post for the solution to the problem.

[EdL.]

My MX Ergo worked flawlessly for the last 3 months inserted front panel Desktop. Only recently has MX Ergo become erratic. SOLUTION : Is there additional devices attached to the Nano receiver such as a keyboard? My keyboard has difficulty maintaining a charge; thus when it goes low charge - it must be affecting the reception on the Nano. Charge up the Keyboard & everything is working fine! Shut down the keyboard - does it affect the mouse operation?

[Tony G Meyer]

I cannot believe this fix. It worked perfectly. I never would have thought of this and I've been an IT professional for 20 years. Kudos for figuring this out.

[Ralph Grabowski]

It happened to me last week, and I wrote this tip!

My cordless keyboard's trackpad was acting up, just could not control the cursor. Then I realized that the nanoreceiver, which I had attached to the end of a USB extension cable, had gotten behind the DVD player. The player is made of metal, so it block the transmission of data between keyboard and receiver.

[Anne Francis Scott]

I just bought a new MAC and have spent a lot of time searching for answers on how to fix a jumpy cursor/mouse pointer. Tried all of the recommended settings changes in the System Preferences (Mouse & Accessibility), and nothing worked. Until I found this post. I'd already purchased the multi-port adapter from Apple, so I plugged my mouse's usb receiver into that and no more jumping around the page! Now I can get to work. Thank you!

[twotinears]

The problem with my mice was erratic. But, this extender solution seems to be working! Thanks!

[Dixie J. Elder]

But I bought the wireless mouse in order to cut down on all the wires. Now we're told to plug in a cord to stop the erratic mouse movements. How Annoying!

[Ian]

I wish I'd found this weeks ago, it's been driving me crazy. I upgraded my monitor a while back and moved the receiver from the monitor USB port to the back of the PC. I've just moved it back to the new monitor and it's working perfectly again.

[ROBERT EARLY]

The longer extension cord worked for me, about 8 feet. My laptop PC is an HP Mini101, running Win 10 version 1903. Nice to know older solutions still work. btw my Mouse is a Logitech M305. FWIW, this pc has only 3 USB Ports, 2 on one side, and the other on the other side.

[Rumen Dimov]

Experienced the same erratic cursor movement. I have two logitech mice, each with its own nano receiver. One of them has the issue though. After reading this, I tried another USB port on my laptop and my mouse is back. My laptop has three USB 3.0 ports, now I use the side one.

[Gary Clevenger]

Nano receiver... move away from computer to extend usb port... wow! who knew? well it worked like a charm for me... now my m570 track ball mouse is golden and doe not jump from everything i point at/// Thanks to users with a brain, I am now a genius... LOL :)
Gary C

[dachief]

when will Logitech ADDRESS the problem?
why should consumers patch their equipment?

[Blue]

You've saved my life. This was driving me crazy for a long time. I've used an USB extender and now it works flawlessly. Thank you!!!!!!!!

[toby]

My Logitech mouse-keyboard arrived yesterday. Ditto to the problems experienced.
I moved the receiver from a USB 3.0 port on the front of my computer (only 3 feet away from the mouse and in direct line of sight).
I relocated it to a usb 2.0 port on the back of the computer (about the same distance but out of the line of sight. Works great.
The keyboard worked properly regardless of the receiver position.

Excellent thread.

[Matt]

I'm so glad I decided to Google this because I was about to trash my M510 which I've had for years and loved! I just got a new HP laptop and I figured the mouse was just old. I moved the receiver to a USB extender and it immediately fixed the issue. Thanks for the help!

[nicho]

I had the same problem for days.
Just tied a rubber band around the received that goes on the PC and now the keyboard and mouse work fine. :D

[Ooi]

Nicho,
I am already using a usb cable to connect to the nano receiver and my wireless Logitech mouse still suffered from the erratic movement problem. I tried your rubber band trick and it works!! I just wrap a rubber band round the nano receiver.

What makes you try wrapping a rubber band round the nano receiver?

[Carole Riley]

I moved my phone from one pocket to the other and so far it's now working fine. Thank you so much!

[Pekka Pouta]

Thank you! -I salute you!

[SS]

So much stupid comments.....
First let ask Logitech and Microsoft what they do with drivers for wireless mouse?
Everyone spoke how signal from receiver is messing with something that come from the computer ?!?
Interesting what is changed inside computer to make mouse that work perfectly almost 2 year acting like a crazy frog?
Let me tell you - absolutely nothing is changed
Just is about a time to spend some money because corporation will stop working.
First - Microsoft refuse (restrict) to use many original drivers from manufacturers because they not have way to test it (actually they don't want to spend money in that direction) and is better to not use them.
Second if you see manufacturers stop making drivers for their hardware especially mouse keyboards and other wireless things.
Even they do - Microsoft delete them after one or two updates.
So I'm not happy to put cable on receiver because if this is thru i need to have receiver with cable from manufacturer.
If they not tested their products we need to stop use them and return these that not work properly.

[sdawd]

I had the same issue. Moved the receiver to the front of the case, no problem any longer until I connect USB stick to the another port near by, the problem came back... Will try this solution, thanks!

[John]

Many thanks. Using a USB extension cable worked for me!

[Rascally Rabbit]

Just about ready to smash this rebel rodent to bits! Thanks!

[RANDY S SHARPE]

The cursor on my Logitech mouse (M220, w/unifying receiver) started "jiggling" without any mouse movement. It started when I moved the usb nano-receiver from the 4-port hub to a dedicated unused usb port on the laptop. Moving it back to the hub (connected to another usb port on the same laptop) fixed the problem.

[Sharon Hrabec]

M310 Logitech is new and mouse works fine on laptop. BUT i CANT DO
NORMAL TYPING without curser moving all over on its own so it wrecks
every sentance I type, I have adjusted sensitivity down to minimum but
not helping. Can you help? Shari

[Mead]

Thanks for this solution which worked for me. For over two years now I had my Logitec M510 mouse parked after it start suddenly drifting to the corner and could only move up and down on two different laptops and a desktop, I could not figure out what was the problem, spent a few hours cleaning, removing parts changing drivers without any improvement, I was on the verge of scraping it.

[Gilad]

Just tried it and it worked for me, thanks!

If the problem persists then I will update here.

Cheers and have a nice Corona holiday ;)

[Gilad]

Yes, it didn't fix my problem. Thanks though

[Todd Gross]

I found that the problem was solved just making sure the receiver had a direct line of sight with the mouse and keyboard making sure that it is not obscured by the computer itself. I all had to do was rotate the Surface Pro 7 90 degrees and the problem when away.

[Matt]

Thanks so much for this. Quick Google search, quick read - boom. Luckily I had a random extender just sitting around and had no use for it...until now! Thanks a lot for posting this - now I don't have to buy a new mouse.

[Bob]

I was suddenly having trouble with my 12 year old vX Nano mouse. Intermittently began acting as if it had no connection at all. Moving did nothing, clicking did nothing, then suddenly it would work again for several seconds and then go off again. Very frustrating.

I just built a new PC. My previous PC was 12 years old, containing several hacks to it to make it work like I wanted. I actually had to dremmel a 2" x 1/3 " hole in the heat sink enclosure of my 9800GTx video card to make room for a USB 3 card. WORKED 100%

So, years later I decided it was time do the new build, as Windows 10 had lots of problems on the 12 year old Frankenstein. So I built a new rig, and swapped over the Hard drives, SSDs, keyboard and mouse.

Built it about 2 months ago. But today Erratic mouse behavior. I have done electrical troubleshooting as a profession for about 40 years now. So I figured I would just figure this out. So I thought about it.

First thing I thought was what kind of signal does this thing use? Discovery: 2.4 GHz (so does one of my wifi routers about 3 feet away from the PC). Also, Microwave overs operate at 2.4 GHz. What about EMF coming from the inside of the PC? This machine has a hell of a lot more power than the last one, maybe it has more EMF leakage? As I sit and stare ot the machine, I realize it has a plexiglass panel, on the same side of the machine as the USB port that the dongle is on. So my first guess was correct. EMF coming from case causing issues with mouse connectivity. I think the fact that I was doing a Non-quick format of my 2TB raid (mechanical drives). I figured that process must be noisy as hell. So I grabbed my old USB extension cord out of a drawer, that I bought back in 2004.

IT fixed the issue. I've used it now for several hours strait with no issues at all.

By the way, it wasnt a line of sight issue. Same distance away, but the receiver is about 3 feet from the PC now.

[Gunel Gadirova]

Thanks very much for this info. it solved my problem with the mouse!

[Richard Lau]

How crazy is it that you buy a $100 mouse and have to google "logitech mx master 3 jumpy" to find out how to fix it. In my case I removed the Unifying receiver from the USB port it was in and put it into a USB 7-port expander that I had and this fixed my issue immediately.

Crazy!

[Ri Beneke]

I have had the same jumping wireless mouse problem.
This forum has provided useful solutions.
I have experimented a little over some weeks to find the cause of radio interference.
Found that a USB extender cable is essential here, mouse and keyboard are unusable without it.
Found a thin USB cable does not work as well as a thicker (branded) one that probably has better shielding.
Also having the USB cable and receiver near a newer monitor and monitor cable gives more problems -
the newer monitor has HDMI ports and cable.
Using the USB cable and receiver near older monitors that have DVI ports and cable does not give problems.

[Giles Cooper]

hello is is now over six years since this original post and I have used it to solve the problem of my janky Logitech M330 mouse. I thought it was strange that my wireless mouse randomly was messed up and choppy laggy and janky in the mouse cursor tracking so my solution was

I moved the 'nano receiver' as it's called from the port in the back of the computer (directly into the motherboard) and plugged it instead into the USB port on the front of the case. Thus the internal wiring of the case filtered out the electrical interference from the motherboard and the mouse works great now.

TLDR: try plugging your wireless mouse dongle into the front of your computer instead of the back

[JR]

Thank you, thank you, thank you! This fixed the mouse issue I was having.

[Phil]

Thanks a lot for your fix. You have just saved me the cost of a replacement mouse. I have been cleaning it, changing battery, nearly smashing it with a hammer and now after plugging it into my BenQ 32inch 4k monitor it's working perfectly again. A very happy linux user here! Cheers

[Win]

Bless whomever posted this about the USB extender. Wish I'd known this years ago!! This just fixed a major headache, and a 6 foot extender was all it needed. I SO wish Logitech "support" had told me this as a possible solution rather than many useless install/reinstall s/w suggestions. Thank you to all who posted this!

[Jim Prolsdorfer]

Excellent advice! I recently had purchased the Logitech MX keyboard and mouse set. The erratic movement of my mouse was driving me to question my $200 purchase. I had tried different USB ports front and back and observed no improvement. Today I tried one of my spare USB cables with a female connector and, presto, it works like a charm! Simple and effective advice! Thanks!

[Ann]

Thank you so much! I already had an extender but it was sitting up against the laptop. I stretched it out away from the laptop and now my mouse is working again. Never would have thought of trying this.... and the problem was so erratic, it was making me crazy.

[Jonas]

Wow! I mean... Wow! You would think that this would be included in the extensive Logitech list of things to try when you have erratic mouse pointer movement, but no. Thank you for saving me from any further waste of time.

[Jan de Vries]

Thank you! My new wireless mouse produced an erratic movement of the cursor. Moving the nano receiver from a desktop USB port to a USB hub port solved the problem. Apparently the new nano receiver is more sensitive.

One would think that the seller (Microsoft, Logitech, whoever) would mention this issue. But they did nothing wrong and they do not make money by mentioning the problem. On the contrary, maybe people will buy another, more expensive mouse

[Sarah T]

OK, and thanks for this possible solution, but no one has answered the question as to why a mouse (various ones of the exact same model, in my case) that has worked perfectly fine for a few years SUDDENLY begin causing the cursor to (as someone in these comments said) "jump around like a crazy frog" and at times to just sit there like a dead frog.

WHAT CHANGED?

[Ralph Grabowski]

It could be due to new radio interference at your place, as wireless mice
use the same radio frequency as cordless phones, WiFi, and so
on.

OK, and thanks for this possible
solution, but no one has answered the question as to why a mouse (various
ones of the exact same model, in my case) that has worked perfectly fine
for a few years SUDDENLY begin causing the cursor to (as someone in these
comments said) "jump around like a crazy frog" and at times to
just sit there like a dead frog. WHAT CHANGED?

I easily solved that problem with the Logitech M570 mouse. I have two of these, and they both exhibit the same problems, one on my laptop and the other on a desktop. Both have their receivers quite far from the mouse proper, so that issue wasn't corrective. The easiest and best solution was that I purchased the Kensington Expert trackball and sent the M570 to the graveyard. This trackball works like magic, much more accurate, no problems whatsoever, highly programmable and so so comfortable.

[Matt]

Incredible.

Thank you. And thanks to all of you commenting that it worked, presumably helping me find this thread at the top of my google search!

This worked! I had my nano receiver plugged into the back of the laptop dock. After reading this, I tested by moving the receiver to one of the USB ports on the side of the laptop, which worked, but obviously took up a port which I need for portable HD. So, I added the receiver to a USB extender on the dock, and it works great! Glad I found this - the erratic mouse was driving me nuts!

I got a wireless keyboard, and was blaming it for my mouse problems. But after reading this, I realized it was because I previously plugged the mouse's receiver into a USB port built into my old wired keyboard, and when I got the wireless keyboard, I switched to plugging the receiver directly into the computer. As soon as I moved the receiver to an external hub instead, presto! Problem fixed! Thanks so much!!!

THANK YOU, THANK YOU, THANK YOU. My new logitech wireless keyboard/mouse combo worked fine for a couple of weeks, then the mouse started skipping like mad. I was ready to toss it in the trash, when I decided to search for a solution. This worked great for me!

To echo everybody else's sentiments - THANK YOU!!! This has restored life to my trusted old (and most expensive) mouse! Since it started stuttering ages ago, I failed to find a solution so have since bought several cheap and not so cheerful mice, all of which have been rubbish. Thank you again!

Let me add an interesting, contemporary twist to this problem. As has been much described in these comments my M705 started misbehaving and became almost impossible to use. Changed the batteries to no avail. Decided to Google the problem and found this thread as a result. After reading all the original post and subsequent comments decided to try the USB extender cord. While preparing to do so, realized I had just installed a Cam Link 4k in the USB port adjacent to the Logitech receiver. Unplugged the Cam Link and instantly the mouse resumed its normal behavior with no problems. Reinstalled the Cam Link and the mouse's erratic behavior immediately returned. Moved the Cam Link device to another USB port away from the Logitech receiver. Problem solved!

THANKS FOR THE SOLUTION SO SIMPLE AND ELEGANT!
My Mouse was erratic, and my keyboard was giving me so many errors, spelling and misplaced space bars and unintended letters that I had not typed, I was beginning to think I might be getting early onset alzheimers!

This worked on my HP laser mouse! All I did was to move the receiver to a USB port one inch away. Also wrapped some Al foil around it with the end left open just for kicks. Thank you for this information.

my problem it seems is actually with the cheap Logitech K220 keyboards USB reciever, creating interference with the M720 mouse. As soon as i unplug they keyboard the mouse performs perfectly. Plug it back in and the mouse jumps itself slowly around the screen. !! Just thought id share incase anyone else had this combo

My Logitech MX Master 2s just started to act sporadic on my Macbook Pro. Instead of continuing to use the unifying receiver and/or extension cables, I merely went to the Mouse preferences and hooked it up as a bluetooth mouse. Now it is working fine and I have a spare useless receiver in a drawer.

thanks the suggestion worked for me

Amazing. I can't believe simply adding an extender fixed the jumpy cursor. I've been dealing with this on my cheap Amazon Basics wireless mouse since I got it. I thought it was just a cheap mouse. Thank you!
