And before you ask, no, I can not put DHCP on a different machine without breaking TV and who knows what.
Do you have a separate modem or something for the TV? How does all that work? Do you feed the TV(s) from a coax cable? Where does the phone connect? It's a serious question, we've got only a coax feed from the ISP that handles VOIP, IP, and TV. I wish we could get a direct fiber connection, but it's not available. Fiber runs down the street here, but it daisy-chains utility boxes in the street that in turn feed RG-6 coax that leads to the houses. One box feeds about eight houses. It's all underground. Inside the house the single coax is split into three with a regular passive splitter which in turn feeds a VOIP modem, my DOCSIS 3.1 cable modem, and a Tivo Romaio DVR. The Romaio is the master of the Tivo network which in turn feeds four Tivo "Mini" interfaces via TCP-IP over wired Ethernet. The Minis are next to the TV's and feed them via HDMI cables. The master has six tuners, so it can handle four Minis and also record two channels for later viewing. It can record six channels if none of the Minis are active. Three TV's lack a Mini, they get their content via IP over WiFi. Tivo is great, it allows us to skip over advertisements! Before you comment on the absurd number of TV's, realize that we have lots of family living here with us. Not that we want them here, but the declining standard of living that we're experiencing here in California limits their options to live on their own, and I don't want to see them living on the streets.
For most common home routers I have seen, the guest configuration is only about giving guests a different SSID and password than the main one. They get IPs from the same pool as the household.
I've got an Asus RT-AC68U that provides an isolated guest network on both 2.4 and 5 GHz. I go further and have that router on it's own isolated subnet on my Zyxel router. Of course I've got IPv6 disabled here as well as on my main router. NAT keeps me as snug as a bug in a rug without complicating my life, it's bad enough as it is. Regards, Lew
