I have a Tapo H200 hub with 2 wireless cameras attached (both model C420s2). I’ve had real problems with them over the last 6+ months. I thought it might have been the TP Link mr6400 4g router that I ran them off(hard wired in to it) but they had been working well on that. But not any more. So I changed router today (more later). But that aside, there hasn’t been a picture in months, when on site or when away. I have re-booted and reinstalled the hub and cameras (many times). I have now changed the hubH200 to my Starlink router instead of the 4g mr6400. The Tapo app says they’re all ok and working well. Signal is great. But still no picture. Battery life on cameras is great. LED lights up when moving around, so they are detecting movement. Firmware is all up to date. Please can anybody help.
