Hi all, sorry for reviving an old post. I am interested in getting an used ERX for my Unifi 300 connection. Currently I am using a D-Link X1870 mesh wifi, and I am thinking to replace it with ERX + Deco mesh (AP passthrough). Has anyone done this before, and is there any benefit in this? My idea is to separate WiFi from routing, where the mesh will simply handle WiFi traffic, while ERX performs the heavy lifting of PPPoE / routing / NAT / DHCP / parental control / etc. This is to achieve stability of the overall setup.
