Look on the outside for the Cable Company connection box

Thanks!

Should be able to. One end should be providing singal.

Yup. Just go ahead and hook it up to see.

If it's filtered or not connected in the box outside, you'll need to do a little extra work.

Hopefully the cable is at least intact all the way to your service.

moca is so much better than powerline

Start by finding where the wires running from utilities poles enter your house. See what branches off from there.

I’ll check this out. I’m using eero WiFi mesh. Unfortunately my pc is hardwired to an eero as far as it could possibly be from the gateway eero. So gaming I DC constantly and even browsing is slow.. maybe this will be a solution vs moving my router downstairs

There are special tools to check for signal but basically yeah do that.

I use a moca adapter to move internet from the main floor into the basement. It's full speed gigabit and it's awesome!

Thanks, but if it’s tv signal, does that mean internet could work too?

That’s the thing, I haven’t seen any other coaxial cables in the house, so I would know what other end to test

LTT did a vid recently on powerline routers and it included coax sender's. LTT powerline adaptors

You could try that, but a better option is to hook up a TV and see if there's any signal coming through

They make connection testers just for this purpose. You plug one piece into the end of the cable and the other piece (of the 2-part cable tracer kit) gets held near suspect cables and makes a noise when you've got the right one. You really only need to find out where the other end of the splice is, so I'd start with your utility closet or anywhere you know there's a splitter

Thanks it will be huge if I can move my modem to this room without running any cables

Ok thanks how would I go about tracing the cables without cutting into the wall?

Possibly. The best way to tell for sure is to try it. Or you could trace the cables.

I literally have no idea where this runs to or why it’s there, it’s in an addition on the house the previous owner did. Should I just hook the modem up to it and see if it works lol?

You can try, but only one may work.

Whether it's connected to your existing coaxial cabling at home and whether it's filtered...these are things we know even less than you do.

Generally you need a common wire.

Old tstats were basically switches.

New tstats need a power circuit in addition to the switched outputs.

Most manufacturers have them on their higher end equipment, but yes less common on shelves because they’re all proprietary for the specific equipment.

I changed guys and houses haha

There’s already quite a few data communicating thermostats on the market!
