I like the Asus RT-AC68U

It has good range and I like the firmware.

For mesh the orbi from Netgear is pretty good.

I think you'd have much better luck with a wired solution if your TV or steaming device has an Ethernet port. I have been using this Ethernet over powerline device for a few years. They are awesome.

I was assuming the house already had cable modem service and you were trying to get it into a particular room.

If the house doesn't have Internet service, then yes that will work, the installer should be able to set it up using the coax in your room rather than the living room. However that one is just a cable modem, which you could get for free from Spectrum. Using a simple cable modem will work if you only have one computer to connect via Ethernet. If you also have a phone, tablet, game console, etc., then you'd either need to separately connect a router (possibly with wifi) to the cable modem, and connect your computer to that, or use something like this which combines the cable modem, router, and wireless access point into one box.

Don’t buy that modem - let them give you one and just get your own router.
If you want maximum performance invest in a delegate router and separate access point.
I swear by the ubiquiti products and highly recommend their UniFi security gateway ( router) and AC-Pro access point.

I’ve got this in my house along with several family members and it’s rock solid on both 2.4 and 5ghz bands.

It's possible to have two different internet services at the same address, but have you thought about powerline networking? It would be a simpler and cheaper solution

USB adapter

Maybe this.

Not true at all. Heck you if you just need basic wifi services you can get a router for below 30 bucks. https://www.amazon.com/dp/B00MRVJYEI?tag=b0c55-20

I bought this one last year. So far so good. Set up wasn’t bad if I remember correctly.

coax latency is already triple that of fiber,
so just get a good wifi antenna for your pc;

there are plenty to choose from, but i would
advise getting anything where the antenna is
on a wire so it can be far away from the card.

the deal where you can't wire between his modem
and your pc is kind of lame, considering the cabletv
company would have run another coax to your modem,
so either way - more wires getting tacked along the wall.
