@ldco1 Hi, the device name could be changed, and did you customize this name before? Could you please also turn off the Mesh technology for the controller?

@TandelK Hi, TL-SG1016PE supports IEEE 1905.1 protocol and would be ok to create Ethernet Backhaul. Thank you very much.

@Robo_Robbie Hi, It depends on you. Deco would work with or without AR1900’s Wi-Fi network, but to reduce the wireless interference, turning off the AR1900 Wi-Fi would be better.

@Heheszek Hi, was your issue like this and if yes, you could try the suggestion on this link: IP & MAC adress of my VM is not viewable in DECO app

@Fionafew Please refer to the suggestion on the other post.

@Fionafew Hi, nice to see you again. Hi, did this error message show up quite often? Have you tried to update the driver on the laptop and desktop to have a look? Could you please refer to this link...
