IP2M-841B loses wifi connection and shuts down

[zihaoyu]

I purchased two IP2M-841B cameras. One works flawlessly. The other one does not work properly.

I used the mobile app to set it up and connected it to the wifi. It stayed connected and worked for about 20 minutes, then got disconnected (indicator turned solid red). After a while it shut down on its own.

So far I have tried the following:

- Different power cable
- Different power outlet
- Set static IP from the camera's admin webpage (while it was working)
- Upgrade firmware downloaded from Amcrest website
- Downgrade firmware downloaded from Amcrest website
- Upgrade firmware in the admin webpage directly

None of the above solved the issue. The only way to fix it is to unplug and plug in again. Any idea how to fix it? It's strange because the first camera worked perfectly. So I don't think this is a compatibility issue between camera and my wifi (Ubiquiti UAP AC Pro). Or can I exchange for another camera?

Thanks!
