Question about TP-Link Deco M9 Plus Triband WLAN Mesh Set of 3 (AC2200)

ok thanks, I will try it out.
Greetings

For proper mesh operation with seamless roaming etc:
Set the sunrise thing to bridge and the main deco to router.

This works perfectly for me with full throughput on UPC.

The providers' boxes are usually weak anyway 😋
