Yeah I don’t think you are going to get a managed switch, AP, and router all in one package that can support all those functions. I could be wrong. But seems less than likely.

Easiest might be just to go unifi for everything and that way it’s all on the same UI. I’m cheap so I have pfsense, cheapest managed switch I could find, and unify AP’s and it still cost me around 300 and that’s with running pfsense on a VM on a server. And it’s a pain in the ass to change configurations because its 3 separate UI’s.

I would prob tone down the segmentation a bit but you do you, it’s your network. I have a mgmt vlan for the router, the vm server, and an old machine I flashed to Linux the pretty much is just used to manage both. That vlan blocks all incoming requests but can make requests to the secondary vlan. The secondary vlan for phones, general use laptops, gaming consoles, etc. The third vlan is for iot which can doesn’t communicate with anything locally. Just points to the WAN interface. There is no need for local management on any of these devices as they all are cloud based (the ones I have). It’s inefficient yes, but it also doesn’t need to talk locally so it doesn’t. As per guests, use your data… oh and my printer lives on its own vlan that accepts requests from the secondary vlan but it’s allowed to make them and it’s hardwired not requiring an additional ssid.

I could be running a shit network though so don’t take my word for it.

Short answer is probably, but depends on how long the power is out. All of the ISP’s field equipment should be connected to some sort of battery backup usually mounted on the pole itself. I’m fairly certain this is FCC regulated as well due to e911 policy where landline telephones still need to work in power outages for emergencies.

Operative work here is should though.

Lazy… it takes waaaaayyyy more time to scotch lock 8 wires then properly terminate. Idiotic, yes very very idiotic.
