CX820 - frequent disconnection / restart

[miffy_690275156107475]

I have purchase a new CX820. I am getting very frequent disconnections has installation on 25/07/2025. The device appear to lose connection and may have restarted after few minutes as it would be lost to network ping.

My own network has not changed settings and the other connected reolink cameras have been stable so far. The camera that was previously connected to this switch port has not had any issues. The network cable used is the one supplied. I have reset the camera more than once.

Has there any reported issue with CX820 losing connection?

@miffy_690275156107475 If it is easy to take the camera down then I suggest you to test it inside using a short ethernet cable into your POE switch. Use different cable and different port. Whilst the camera could be faulty in the vast majority of the cases like this the culprit is a bad ethernet connection.

I have a similar problem.
Bought 6x CX820 in July.
One, often works well, but often drops a gazillion packets and is unusable.
Often, the issue starts at night when it's dark.

Tested the Ethernet cable with a RJ45 tester, and it looks OK.
I am trying a different port on the PoE switch at the moment, and the jury is still out.
The PoE switch is not power maxed-out, by the way.
What is interesting is that it does NOT happen all the time.
This makes me think more software bug.
On the other hand, the other cameras don't seem to have a problem? Very weird.

@giro83_971858645299369 Since you have another 5 which are working without issues and you have changed the cable and the port with a functional one then I suggest you to open a ticket with Reollink if you bought it from their site. Else if from Amazon ask for a replacement.
