Horrible Logitech Mouse Lag

[modem]

Hey all,

Since getting my M720 mouse last summer, I've gotten horrible lag with it that comes and goes at will. Initially I thought this was related to a failing hard drive in my PC tower. So I replaced PC's and with a new x570 Ryzen system, the mouse is still lagging bad.

I've used it with both bluetooth and wireless dongle. Lag doesn't dissipate when using one over the other. Then I thought I had a bad mouse and Logitech sent me a replacement... however that lags just as bad and in the same way as the first one I bought.

When I say lag, moving the mouse around the cursor has hiccups of about .25-.75 seconds where the cursor doesn't respond to mouse movement, and then it tries to catchup to the last best position I had moved the mouse. It's so bad I have to either not use it or wait for when the lag suddenly goes away, or get a wired Dell mouse.

I've ruled out PC's, the mouse itself being bad, and even have an older Logitech M510 that doesn't seem to be affected.

How do I fix this? I love the m720 because it fits my large hand perfectly and would hate to go to a subpar fitting mouse.

Is it laggy in Safe Mode?

Look at your CPU/Memory usage. That could be lagging because of that.

Could also be a bad driver. Did you install Logitech's driver and software?

Edit: In you sig.. "1.0GB PC3200 (Dual Channel)" Does that mean you have 2GB? Umm..

I don't think he'd be running a P4 in 2023 not XP

Where did you plug your dongle in for the mouse? If it is at the back of the pc, you might be getting interference causing the lag... i have the same exact issue with my logitech G502 lightspeed... since i got a USB hub, and plugged the dongle into it, and positioned the hub at the end of my desk, almost in line of sight with the mouse, issue went away!

I seriously need to update that sig.  It's only been in place since like 2003 not long after I joined Neowin. lol

FYI, Cpu and memory usage are all low.  Ryzen 5800x and 128g of ram.

Could be RF interference. Also could be some software side interfering.  I've personally only ever seen that when my system thermal throttles.   Does it do it when your in your motherboards firmware? (if it supports a mouse that is) otherwise try a linux live image and see if it does the same thing.

Yeah like @Sulphysays where the dongle is plugged in can be the issue. I recommend a USB extension lead, run it from the PC and tape it to the back of your monitor so the distance is quite short. They are quite inexpensive.

Yeah I remember having problems when the mouse dongle was plugged into the back of my computer case under my desk.

Thankfully I now have a Corsair mechanical keyboard that has a USB port about 10 inches from my mousepad.

Thanks for the input on this.  I do have a dongle that is plugged into a USB2 port header on the front of the tower.  The tower sits on my desk and the receiver is maybe 2' max from the mouse.  That has helped mitigate the issue some, but about 40% of the time it comes back and the mouse lags horrifically.

I do have two monitors beside the tower.  There is a Fortigate firewall, Netgear wifi router, Comcast cable modem (modem only) and a speaker w/sub.  

I have moved the receiver from USB 3 to 2 as I've read 3.0 ports can cause interference as well.  Connecting the mouse via Bluetooth is still basically impossible.  It used to connect after I put this PC together back in Nov, but now the bluetooth mode in the mouse will connect, disconnect, connect, disconnect, etc.

Hello,

Out of curiosity, goes disabling the 2.4 GHz radio in the Netgear Wi-Fi router make any difference with the 2.4 GHz Bluetooth connection to the Logitech mouse?

says it happens with bluetooth as well - so that rules out 2.4ghz interference I would think.

I have a logi MX Master S3, have had zero issues with it.. It doesn't use the 2.4 dongle it use the bolt, which is low energy bluetooth on its own.

When they sent you the new mouse, did you try it on both bluetooth and the dongle as well.  Did they send you a new dongle as well?

How exactly did you rule out the PC? Have you tried the mouse on a different box, do you have a laptop or something else you could use the mouse on?

You sure your not like connected to both the bluetooth on the pc and the dongle at the same time?

Hello,

Both Bluetooth and Logitech's Unifying Receiver operate at 2.4 GHz, which was why I was wondering if proximity to the 2.4 GHz band radio in the Wi-Fi router might be a factor.

In my experience the Logitech dongle was really fickle. It only ever worked properly when I taped it to the back of my monitor. So although distance wasn't the issue, it definitely indicated some interference issue with my PC or devices near it.

While true, bluetooth and wifi are designed to not interfere with each other.. The channels used don't actually overlap  - so unless he is using some non standard 2.4 channel 1, 6 or 11 it shouldn't be a problem.. But you point is valid.. Turn off 2.4 wifi to see if still has issue.

As to BLE - studies I have read show for sure there shouldn't be a problem.

This assume proper use of 2.4 wifi.. Or properly operating equipment.

Wireless mice using 2.4GHz have been around for a long time.  The mouse I use... Logitech M510... came out in 2010.  And plenty of other products use 2.4GHz too.

So if there was some widespread problem using these frequencies... we'd hear more about it.

As I said before... my problem was distance.  But I moved the receiver closer and it's been working fine for years.

[Ixion]

Are you using the same windows install on the new machine?

Being really close to the transmitter can cause problems all of its own, as you're in the rf near field before the waves have a proper chance to be established although 2' should be OK at these kinds of frequencies.

If you have logitech hub software installed I would try removing that and see if it improves things any, in my experience it's a very bloated but of software just for setting rgb colours on a mouse!

Agreed with this, but make sure you save your current profile to your onboard memory mode first (you may have to select "Replace with" and then select the current software profile you are using.)

GHub is really only necessary if you are switching between gaming profiles I think, and I can't remember if the lighting goes off when the PC is locked without GHub, I would have to test and report back.

Yes, I tried the new mouse on both the bluetooth and dongle, no change in the results.

I tested on another laptop I had nearby with the same symptoms for both bluetooth and the dongle.

Definitely confirmed that the mouse can only connect to one method at a time.

Interestingly enough, I've been using the mouse on the 2.4Ghz dongle for several days with no issue.  I have it connected to a USB hub that extends down over the side of the tower plugged into a USB2 port on the top.  However, when connecting via Bluetooth, well it won't even connect at all sometimes that way.  In fact when I tried it moments ago, it says "Can't connect to mouse, please try again" when trying to pair the devices together.  I'm leaning towards some sort of bizarre interference.  

However that doesn't explain why Bluetooth won't even pair at all right now unless I'm missing something on the pairing side of things.

Hello,

Just to confirm, you have not tried disabling the 2.4 GHz band in your Netgear Wi-Fi router yet for testing purposes.  Is that correct, @modem?

I have the same mouse and I notice similar lag every once in a while, but not consistently like you are.  I am connecting with Bluetooth and share the mouse between a desktop and a laptop and also have the matching keyboard.  A reboot has always fixed the problem for me.

Make sure that you have the latest firmware in the mouse.

[limok]

I had the exact same issue with the Bluetooth dongle. I found that if it was too close or too far there was a lag. 

 

The fix for me was to get a usb extension cable and let it dangle behind the desk. 

 

No issue since then. 

[modem]

Looks like it was the 2.4Ghz interference.  I have a wireless router about 2' away from where the mouse sets.  I disable 2.4 and everything is fine for days at a time.  Turn it back on and the issue almost instantly reappears.  Yet still only seems to affect this Logitech, but maybe it's because my other mice are slightly further away (3' vs 2').

[goretsky Supervisor]

Hello,

Based on your description of the problem, that's what it sounded like the problem might be.

I would suggest looking around to see if you can determine the exact frequency (frequencies?) used by the Logitiech M720 mouse, then contact Netgear and find out how to determine if there is any signal overlap between the Logitech mouse and your Netgear Wi-Fi router.  It could be that it is a matter of changing channels in the 2.4 GHz spectrum.  Or, if there is no frequencey overlap, it could be that there is an RF shielding issue with the Wi-Fi router, in which case that is something Netgear will have to fix.
