Deathadder V2 Pro randomly disconnects

THE PROBLEM:

This problem started a few weeks ago. I’ve had this mouse for around 5 years, I’m pretty sure.

In random times-seemingly, the mouse just disconnects for a few seconds then goes back on. This only happens in wireless mode, it doesn’t happen in wired/Bluetooth. This problem occurs with Synapse being both off and on (off = task stopped, not just app hidden).

ADDITIONAL NOTES:

I did notice certain things that always make the problem occur, such as selecting an area on the screen with the snipping tool.

MY SPECS, DEVICES & APPS:

  • Windows 11 Pro
  • Razer Deathadder V2 Pro
  • Razer Mouse Dock Chroma
  • Razer Synapse 4
  • Razer Chroma App

THINGS I’VE DONE THAT DIDN’T HELP:

  • Uninstalled (there were no updates available for them via Windows) all related drivers via Device Manager.
  • Ran a script to uninstall all drivers and their leftovers - I found the script in an Insider thread.
  • Reinstalled Synapse (4) and the Chroma app.
  • Tried multiple USB ports on my PC.
  • Followed this guide I found in an Insider thread.
  • Restarted my PC.
  • Updated Windows (including Optional Updates) and checked for updates.
  • Ran the Firmware update executable for the mouse. It had no updates available.
     

I’d really appreciate some help regarding this.
