Cool, that’s exactly what my plan is currently. I will eventually run all the cables but I want to drop in this firewall and start learning it in the meantime.
I may even go the route of some managed switches and WANs that do support multiple SSIDs on different VLANs, but first I want to get comfortable with my new single network.
Just wanted to update everyone that the wireless router does turn into a 5 port unmanaged switch when changed to AP mode, and that the topology of Modem -> AP’s WAN (this is now a Lan port because it’s a switch) -> devices is working great!
