@TP-Link Could I also please have a copy of the firmware. Thank you. I am havung the same issues.

@xkenxken Also need the firmware. I have the same issue. " My current firmware is : 1.5.3 Build 20210203 Rel. 68223"

@TP-Link Has this issue been resolved yet? I just bought a set of 3 and an extra one and I am finding that my slaves all connect to main unit even though there is a closer slave with full strength...
