OK, I changed locations, but the modem is less than 2 meters from the camera. The values are now between -50 and -51. The LEDs are always off when it goes offline; they never turn red or orange, and this has always happened to me. In fact, the camera still works and records properly, but communication with the app and the device is blocked. I found the router model; it's a HomeHUB4 supplied by Sky, version 001.

Hi  @Solla-topee 

I recently purchased two C500 and one C210 and one C310. Same issue with the C500s. Both are hw ver 2 and on firmware 1.1.2 Build 250326 Rel.61993n. No issues with the other two models.

The devices are visible on the tapo app for a while and then appear offline after a while. Both are visible on local network as I can ping the camera IPs. The only way to get them back online is to power recycle. RSSI is -50 for one and -60 for one. I already tried replacing my AP as well as moving closer to the cameras but same issue. I also changed the dns to 1.1.1.1. the power adapters are also the original ones supplied.

Can you suggest what can be done? I am happy to try any new firmwares if available.

Edit: i have a local NVR that accesses the streams via ONVIF. Both C500 streams are continuously available but the tapo app shows both as offline. The C210 is also connected to same AP, ONVIF link can be accessed locally, and also shows as online in tapo app.

After a month I can say that the problem has been solved, technical support contacted me after a few days and solved the problem, really a round of applause for this, it made the difference and created a solid basis for being able to purchase other Tp-Link tapo products.
