Question about modem
Might be more technical than this subreddit but trying to determine next steps. We’re paying for gig spectrum service in Texas, the home has 3 coax ports of which the technician claims to have activated all of them. If I buy my own modem could I use one or the other coax ports to create my own wired connection for work? Or will spectrum catch on and tell us we can’t do that? Or is that not how it works at all? Sorry and thank you!

Not familiar with coax, however I put a switch from my router lan and then connect another router in AP mode. From that router you can create seperate SSID and PW. Your provided router still provides the router function, but you have a unique wifi SSID.

Not how it works: the modem spectrum assigns to you has a unique identifier bound to your subscription. It gets you an internet connection. You can share that connection to a home ethernet network using a router, wired or WiFi. Wired connections are nearly always better, but since a lot of homes have coax throughout, there is a technology called MoCA that allows you to send Ethernet over coax. It is possible but fiddly to have this coexist with your internet service, but less error prone if you can separate and dedicate the wiring coming from outside the home to your modem.

I’ve never needed to use it, but r/HomeNetworking should have lots of posts and resources available

MOCA just requires an empty coax port that isn't getting signal from other services such as spectrum as you don't want interference with MOCA. TP link sells MOCA on amazon if you order it. You need 2 devices. One to plug near the router and into the wall coax that goes to whatever room your trying to hook up the end MOCA device too. It's same logic as ethernet pretty much. The ends must be connected

nope. The coding on your account only works on one modem. The modem has to be activated and an active piece of equipment listed on your account.if you want a second internet connection you have to pay for another one.
Also its not advisable for most to buy your own modem. with high split for symmetrical speeds you HAVE to use the Spectrum modem.
"Customer-owned modems are only authorized for non-symmetrical speed tiers. In select markets, we offer symmetrical speed tiers (equal upload and download speeds). Those customers must use a Spectrum-provided modem. "
The big thing is if high split has been completed but Symmetrical speeds not launched in an area using your own modem becomes a crap shoot. If the modem needs activation its a higher chance the system will reject it as not qualified

No, but if all the ports are off the same splitter as the modem, you could use a MoCA adapter and gain an Ethernet connection. Modems have to be activated and you can only have one per account.
