DeathAdder V4 Pro connection quality switching between green to yellow frequently

Hello,

 

I recently bought a DeathAdder V4 Pro and noticed an issue with the wireless connection quality indicator on the dongle.

 

The connection quality randomly switches from Excellent green to Good yellow, even when the mouse is not moving. It can stay yellow for a few seconds like 20-30 then return to green. The dongle is very close to the mouse, so distance should not be the problem.

 

The mouse firmware is up to date. I also reset the mouse drivers through Device Manager, but the behavior did not change. I purchased the mouse 39 days ago and this issue appeared today, or I may not have noticed it earlier.

 

I saw that another user reported the same behavior and received a reply from Razer staff, so I am wondering if this is expected behavior or a known issue.
 

Is this expected behavior or a known issue with the DeathAdder V4 Pro hyperspeed gen 2 dongle?

Other devices still can interfere with the wireless signal, despite dongle being very close to the mouse.

Just be sure that mouse and the dongle are away from any power outlets, and even USB 3.0 devices (which also can interfere with the signal). Also how many 2.4GHz devices are enabled in your environment (like BT devices, WiFi networks etc)?

    I’ve checked everything you mentioned. The dongle was in front of my PS5, but I’ve moved the console completely away, and the issue is still happening. Only one device on my network is using the 2.4 GHz band, the PS5, which is now far from the dongle.

    The mouse and dongle are also away from outlets and USB 3.0 devices, so nearby interference doesn’t seem to be the problem. It’s a bit strange because Razer Synapse also fails intermittently, showing installation failed error and saying there’s no network connection.. it’s annoying too because this is my first wireless mouse, what else could the problem be?
