Reply to comment by Synaps4 in Can I hook modem up to a coax splice I found behind a blank plate? by jaxclayton

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?

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

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.

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

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

Yes. They're both carried over the same wire

My setup has a filter so that no TV signal goes to the split that feeds the modem, but there's no filter on the TV ones. So, a TV signal MIGHT also have the internet signal, but no TV signal doesn't automatically mean that there's no internet.

There shouldn't be high voltage or anything that would ruin the mode, so give it a try. It's easier to move your modem and router than a TV and THEN your modem and router.

Not all setups ate like that, though, and OP might have a TV more readily available. And, and, and...if there is a TV signal, there will be an internet signal. Also, it's easier (faster) to see if the TV has signal than waiting for the modem to fail a handshake

However, if his setup is like mine (and I don't know why mine would be unique), testing the TV and finding no TV signal wouldn't preclude there not being internet available. Plus, if there *is* internet at that location, he needs to move his modem there anyway, may as well do it right and test the thing you want to test (will modem work there), not something similar (is there TV signal there). On top of that, if the wire isn't connected to *anything*, he'll need to test the modem there to rule out the situation being like mine.

I wasn't trying to correct anyone's statement...I was trying to show how:
a. He may come to the wrong conclusion using a TV to check
b He may end up doing double the work--testing with a TV, and then having to test with the modem and move the modem there anyway if the TV tests out with signal.

Like all internet advice, opinions and experiences, one needs to see how the similarities apply to oneself and how the differences need to be accounted for.

Ok thanks I thought I had read some coax was tv only! I appreciate it

Coax can be TV only because it's like old coax for an antenna or old coax that was hooked up to a satellite system or some other system that isn't connected to like new coaxial cable wiring.

Times when they come in with the cable modem they just run a brand new line right to the cable modem instead of using the existing houses cable TV wires.

Sometimes they wired into the houses TV wiring but basically that's more prone to having problems doesn't really give a lot of advantages since most people don't need to move their cable modem around much.
