We recently purchased  2 pack Deco X68 system to replace a Synology router + 4 Netgear AC 1200 extenders.

The new mesh system is working great, except I would like to use 1 extender still to bring a connection to a network switch.  This worked just fine with the extender + router before.

When I attempt to connect the extender to the Deco, I am able to connect to the WIFI but there is no internet signal.   Have tried multiple times and have done a factory reset on the extender.

Given this is my first mesh system, is it by design that you 'cannot' use an extender with mesh?  It seems like the DECO is just blocking the extender from getting to the internet but letting all other types of devices through.

I understand I could buy another Deco unit to do the same thing - is this absolutely required vs using one of my extenders??
