@Melon-Head i had the same issue all my network devices at home in one mesh compatibility and all of them are tp link brand with wifi 6 certified: AX3000 4-Stream Wi-Fi 6  Router Extenders: RE600x and 605x  and the tapo c225 wi fi 6 advirtised i found the solution by disabling the smart connect feature in the main router and seperate 2.4 and 5Ghz wi fi names and connect my camera straight over 2.4Ghz and it never lost connection again. What means this? I can't get them work under one wifi name which one of the feature of wi fi six in one mesh. I think TP link either aren't aware of how their devices work buggy or they pretend they don't know what is going on. Those extenders are all in one mesh combility list yet they can't communicate without going buggy like dropping whats app calls during talk. it's a malfunction engineering.
