@David-TP my iPhone showes up 2 times in the network one time at the slave deco wireless and one time at the main deco wired :) also 2 different ip adresse and I am sure I don't own 2 iPhone 12's 😉

Same issue with the a22 5g of samsung i think this is not a tp link problem because I have it also with other networks, Linksys and ASUS i have shoot in a ticket ad Samsungs support, but no response...

@JanRekenaar Jan, also do not regornize this problem. I have a netatmo doorbell, nefit easy and some Tuya network lamps, running on 2,4 ghz and 5ghz. But the only thing I have is Ethernet backhaul 3x...

The day after release of the firmware installed, it’s stable and I did not found any bug yet :) Ps I am on a beta with the deco app using version 2.13.12

@JanRekenaar If you do it manually than you only have to install it on the main deco. i have v1 and v3 in deco in my network all connect with Ethernet backhaul

Updated my deco's 3x v1 1x v3 2days ago. Running stable and smooth till now. So I am happy with it 👌
