I have experienced similar problems with Deco X50 (V 1.0) and firmware 1.6.3 Build 24112112 Rel. 78921. One of my cameras (Reolink Argus 4) stopped working and I had to reset it many times. Rolled back to 1.6.1 and camera is now working well. The strangest thing is that I have 6 Reolink cameras and all of them were worning well with 1.6.3 firmware. The only one which didn't work was the Argus 4 model; Agus 3 and Argus Track models were working correctly. Deco App was showing Argus 4 as if it was connected by LAN cable and not by wi.fi, that was the only difference I noticed. Initially I contacted Reolink bacause I was thinking of a camera malfunction but then I remembered I had updated the firmware two days before... My actual setup is 3 x DecoX50 (one acts as main router), 1 x Deco M4 e 1 X Deco X50 Outdoor. Most of them are connected by Ethernet, only two Decos X50 are wireless connected between them. By creating a IOT dedicated network and by using that network with Argus 4, it was correctly working even with 1.6.3 firmware. However I rolled back firmware for security purpose
