Secondary WIFI Networks: VLANS or SSID, or Both?

[chigden]

There's a lot of information aimed at different levels so I'm confused how to achieve what I want. I have an Asus Rt-AC3100 and I want to set up multiple, isolated networks that connect to the internet. The primary network would be accessible through wifi/ports but all other networks would only be accessible through their respective wifi ssid.

My questions:

Will the standard 'guest network' feature do this?

Can it create multiple guest networks?

Is a guest network restricted or crippled compared to the main network?

Will each guest network be on its own subnet (192.168.1.*, 192.168.2.*, etc)?

And then, if I'm looking at flashing merlin, does that change anything?

At what point would I need to create multiple vlans?

Yes.

Yes. 3 guest networks on 2.4GHz and 3 guest networks on 5GHz.

Is a guest network restricted or crippled compared to the main network?

Selectable. You choose to give the guest networks access to the LAN or not.

Will each guest network be on its own subnet (192.168.1.*, 192.168.2.*, etc)?

No.

And then, if I'm looking at flashing merlin, does that change anything?

I don't think so.

At what point would I need to create multiple vlans?

You don't. AsusWRT doesn't support VLAN's.
