Logitech MX Master 2S disconnect issue

Logitec MX Master 2S disconnect.md

I am using a Logitech MX Master 2S mouse since a while. In recent weeks/months, I see occasional disconnection issues.

Question:

It is unclear whether this is a mouse or a Windows 10 update issue. How can I diagnose this further?

Details

• Logitech MX Master 2S mouse
• Recharging mouse doesn't help
• Connected via Bluetooth to Windows 10 laptop as device 2
• Windows version:

Observations when things go wrong

• Using mouse without any problem
• Suddenly, mouse cursor no longer moves when moving the mouse.
• Light of active profile (2) blinks.
• Device is still connected according to Windows

Workaround

• Add the mouse again as a bluetooth device in Windows 10.

OR

• Turn airplane mode on/off in Windows AND turn mouse off/on

Frequency

About once a week

History

• Asked Logitech for help https://twitter.com/jawndotnet/status/1198914083380178944
• Then opened Logitech ticket https://support.logi.com/hc/nl-be/requests/1947798
• Reported issue on Microsoft Feedback Hub https://aka.ms/AA6o8h7

Huh, having the same thing! The light underneath the mouse actually flashes during these disconnect events, so I know something is up.

I've encountered this issue as well. Not having Logitech Options didn't solve it. But I noticed that whenever I opened the Logitech Options configuration, the previous inputs all happened in an instant.

That brings me to a successful, painless workaround: leave the Logitech Options configuration app open.

Update on this: the Wifi 6 / Bluetooth card I was using was probably faulty.

I faced the similar issue right after Win has been updated to build 2004 on my Acer Aspire V Nitro.
The problem is MX Master 2S disconects after comp goes to sleep and doesn't reconnect after. If you want to connect it again you should restart comp or remove the device from Windows. Turning flight mode off/on doesn't work. It turns out that if you turn off bluetooth before swiching off your computer it keeps off you from sudden disconnecting for a couple of days...a week maybe (sounds weird..but..)
Now I'm on build 20H2, updated Logitech driver - nothing changes
Things I used to resolve this issue (hope it helps someone):

• To remove the device from system and reinstal it (Using Windows ->Settings-> Bluetooth and mouse -> Remove device)
• Remove the mouse and dependancies (drivers) using devmanager and re-install after
• Turning off 'Power saving for bluetooth device' (you should run devmgmt.msc as administrator, after HID devices -> Power managment)
• Remove and reinstall all dependancies as administrator
  Finally I have no idea what to do with this...Any idea? :)
  Warranty has run out and it's super annoying

The problem is MX Master 2S disconnects after comp goes to sleep and doesn't reconnect after.

This is one of those situations where I'm happy, but also sad that I'm not the only one experiencing these issues, albeit on the MX Anywhere 2S.

That brings me to a successful, painless workaround: leave the Logitech Options configuration app open.

Hoping this works for at least my personal rig...

Same problem here. I have latest updates but my MX Master 2S from time to time disconnect for 2-3 seconds and then it works. But this happen more than dozen times a day so Logitech you really need to fix this issue or send us replacement.

I have an issue with my MX master 2s where it connects fine with bluetooth as well as the unifying dongle, but the scroll does not work at all. I have to use the gestures button to pan around the window. But the vertical scroll is so much more convenient to use. Firmware as given in Logitech options is 012.00.00003. I see others have a better firmware version. How does that even happen i dont know. I tried everything including opening the mouse, firmware update tools, logitech options, everything. If i can just reset the firmware to another version, my problems might get solved.

3 computers, Mac mini M1 running Big Sur & Mac mini 2012 running High Sierra (running Windows 10 in BootCamp about half the time) connecting with unifying dongle, plus a Windows 10 (Acer TC-710 tower) computer connected over bluetooth. Logitech MX Anywhere 3 for Mac mouse, MX Keys for Mac keyboard. Random disconnects resulting in jerkiness with the mouse, keyboard gets out of sync with mouse and then cannot switch between devices (even Easy-Switch no longer works, keyboard choice key gets stuck on a single computer.) Try to turn off Flow which sometimes works for a while, but then the issue comes back. Best long term solution is to reboot computers at which point it may work for a few days before becoming problematic again. Running all latest updates on Mac, Windows, Logitech mouse and keyboard running latest firmware.

So after more than a year working smoothly using Bluetooth (once it had a small hiccup but it was resolved quickly), I am having trouble with it. I needed to change the BT card in my old Macbook pro mid-2012 13" because it was having erratic connection when >2 BT devices are connected.

All seemed fine after I replaced the BT card; I could quickly reconnect my Logitech keyboard K380 and a BT speaker, but for almost an hour I was trying to reconnect my mouse with no luck. This mouse is detectable on my Android phone, so there's no power problem here.

I've followed the guide here: https://support.logi.com/hc/en-us/articles/360023195654-Resolve-Bluetooth-Wireless-issues-on-Mac-OS-X
Still, nothing changes.

Then I try the dongle and it works! However, having used the BT way for so long, I am very curious as to why it just don't want to work anymore.
