@ugscavcg assuming you have FTTC broadband and not full fibre? What settings have you used so far? Have you tried the Plusnet hub in router mode and changing the Deco to access point mode? Maybe try...

@David-TP Perfect, thank you.

@David-TP Hi, is Eco mode available in access point mode? Thanks Kevin

Great, good luck with getting the DV sorted out. The BT community forum is also a good place to post for BT issues with lots of helpful people there too.

Also check the easymesh feature on the AX53 main router is switched Off.

@noris_sasaran Hi, I had a similar problem with my X60 Deco in AP mode, my main router is an Archer C80, on the Deco app go to "advanced" and disable "smart DHCP". Worth a try.
