Hi, 

I changed to a new service provider yesterday and my new router is a Tp-Link Aginet HB610 (BE9300 Whole Home Mesh Wi-Fi 7 AP)

I already have a set of 3 TP-Link Deco M4 AC1200 Whole Home Mesh Wi-Fi System.

My new router has been set up and working fine but I've reset my 3 deco units but unable to add them as mesh devices. 

I have one unit plugged into the router with an ethernet cable and the other 2 elsewhere. 

I don't want to set them up as a separate network, I'd like to have them set as extenders as I had on my previous BT router. 

All have been reset and flashing blue but neither the Aginet app or the web interface will pick up the mesh devices. 

I set them up in the Deco app and set them to Access Points as this worked fine previously but now even set as an access point they don't seem to work with the router and still appear as it's own network. 

The deco units don't have a WPS button to try that option.
