V3 Pro stuttering and disconnecting

I purchased the Razer V3pro on November 30th, 2025, BRAND NEW (just to make sure I clarify that). The mouse is great WHEN it is working. I’ve been intermittently experiencing these issues since the first few days of use. 

 

I thought it could be interference issues, so I:

1.) moved the wireless dongle

2.) changed the usb port being used by the mouse

3.) changed the port I use for my wireless headset’s dongle

4.) use my wireless headset in WIRED MODE

When this didn’t work I:

5.) installed and updated drivers through synapse

NOTHING WORKED…

AND I’m STILL having issues. The mouse will just turn off randomly for 3-10 seconds and then cut back in and the light will blink a few times or it starts lagging, stuttering and just completely becomes UNUSABLE. At this point I have 13 more days to return this and I hate returning products but this is unreal. Should I just return it and go back to FinalMouse, like this is so unacceptable.

 

PLEASE HELP.

Hey there, ​@Eternes 

I understand that you are having issues with your Razer Viper V3 Pro randomly turning off, lagging, stuttering, and becoming unusable during wireless use. Could you please confirm if the issue occurs with or without Razer Synapse running in the background?

Additionally, please try these troubleshooting steps below to help resolve the issue. 

  • Power is important. Make sure your mouse is fully charged.

  • Switch it ON. Make sure wireless mode is ON or the mouse is switched to the correct wireless mode.

  • Verify Windows is up to date.

  • Connect the USB dongle directly to the PC and verify there is a clear line of sight from the mouse to the dongle.

  • Update the firmware on your mouse if it is on the list.

  • Download and run the Pairing Utility for your mouse. If your device is not listed, skip this step.

  • Check if a software is causing the issue by closing all Razer apps and software.

    Razer Synapse on the system tray

  • If closing Razer Synapse fixed the issue, reinstall your mouse drivers, and perform a clean reinstall of Razer Synapse.

Test your mouse on another PC and verify if the issue still exists.

 

If the issue persists after performing the troubleshooting steps, please send me a private message together with your device's serial number and proof of purchase/receipt in PDF format so I can check its warranty details for a possible warranty claim. You can upload your proof of purchase to your Google Drive and send me the link. Make sure that the link is set the sharing settings to "Anyone with the link can view". Thank you!
