Hi @Dud3
While @Black Mamba s approach will create two different SSIDs, keep in mind that it will
a) stop one SSID from being available via 5 GHz, and the other from being available via 2.4 GHz
b) the networks won’t actually be separate - it will be just another “name” to connect to - which imo defeats the purpose of having two different networks.
Sadly, apart from the guest network, the internetboxes do not support multiple networks. Also, you cannot control the firewall-rules of the guest network, which will break i.E. Chromecast / Airplay etc.
If you want to build a more complex network, you will have to get an additional firewall + APs.
Best,
