@Marvin_S My issue has been resolved when i give my client devices a static ip address and after that names are always remain same.

@David-TP I changed back to 255.255.255.0 because i had connectivity issues with IoT Devices on 255.255.252.0 but my old issue came back after i changed back to 255.255.255.0 here you can see Unable...

@Marvin_S I tried to turned OFF Randomized MAC Address and still same problem and i also tried to change IoT Devices names and still same problem.

Hey TP-LINK !! Why my connected clients name back to default in Deco App after few hours or next day? I was facing the same problem on previous firmware like 1.6.5 and others but i have'nt faced this...
