Configuring a VLAN over a repeater (AC5300 / AC66U)

[goncalossilva]

Hi everyone,

I'm looking to do a setup which I'm unsure if it's possible. I have little experience with VLANs so please bear with me. All advice is welcome.

I have an AC5300 connected directly to the ONT. In "LAN - IPTV" I selected my ISP profile, and now I can connect my ISP's router (TG789vac) to port 4 and have my TV Box / Phone working correctly. Something like this:

ONT <--wire--> AC5300 <--wire--> TG789vac <--wire--> Box / Phone

Recently I added an AC66U as a repeater to extend the wireless coverage. I would like to connect my ISP router to the AC66U, and have the box and phone connected to it. So:

ONT <--wire--> AC5300 <--wireless--> AC66U <--wire--> TG789vac <--wire--> Box / Phone

However, my ISP's router doesn't even acquire an IP address. I'm using the latest Merlin firmware on both (380.62_1).

Is this possible at all? If so, any pointers on what I need to do to have my setup working? Any advice would be appreciated. Thank you!

If it helps, on my AC5300:

# robocfg show
