Subject: Viper V3 Pro disconnecting via dongle and USB – urgent help needed

Hello,

I have a Viper V3 Pro, and out of the blue it started to disconnect from the dongle at least five times per minute. When the battery finally ran out, I discovered that the mouse still has the same issue even when it's connected via USB.

And it's not like it disconnects and instantly reconnects — sometimes I have to wait a couple of seconds, other times up to 30 seconds for it to work again.

I've already tried everything I could think of:

  • I charged the mouse using all the USB ports on my PC.

  • I even tried charging it using my iPhone charger, but it still connects and disconnects — even when the PC is turned off.

  • I uninstalled Razer Synapse.

  • I followed a guide from the community support that instructed me to delete all Razer files from my PC — but nothing changed.

  • I also installed the mouse firmware that was released in September, but that didn’t fix the problem either.

What's confusing is that both the dongle and the wired connection are affected — but it's just the mouse. For example, if I disconnect the dongle and plug in my phone instead, my phone charges perfectly. Also, this started so suddenly — just yesterday I played CS for five hours straight without any issues. Now I can't even scroll through Google without the mouse disconnecting, whether it's using the dongle or directly via USB.

Please help — I’m out of ideas and the mouse is unusable right now.
