They would (or should) run the working cable into the house. Once inside, then it's your responsibility. They should, however, install the cable modem on it too. Don't do any work that you dont know will be used by them when they come out. It has a good chance of being a wasted effort.

Before they get there, you'd need to run the cable inside, and connect a modem to it, and have them configure the modem, sometimes it can be done online but often you need to call with the MAC address. And that's IF that cable is the correct one.

It will not work. Modems have to be provisioned by the head end before they will connect to the internet. Even if your modem was operational before the move, chances are that the cable that you are attaching to is not connected at the tap (cable hookup for your general area).

There is 0% chance that you can do this without them.

If the line was connected on the other end, the modem should at least sync up with the CMTS and keep you in the walled garden. Then OP would know if it was the right cable.

Based on OP's post and comments, they probably don't know how to put a proper compression fitting on. This matters because those shitty crimp on fittings that people buy should NEVER be used on cables connected to an ISP.

The frequencies running on coax are the same ones used by air traffic to communicate (as well as tons of other frequencies). Crimp on fittings do not keep all the RF inside the cable and can introduce noise into the system. Not only that, but they let those frequencies out into the air.

While the RF radiating out of the cable line isn't harmful to humans, it can be picked up by all sorts of things that shouldn't be able to hear it. Then cable companies have to drive around with an RF sniffer to find these leaks.

So maybe OP can just throw a fitting on and connect it, but as someone with a basic grasp of these systems, I would highly recommend leaving it be.

Edit: but, the forgotten word

There is a 0% chance it can work without them at all, but that's because (minimally) they need to provision it on their end for the modem to function. It may be connected at the tap.

I've definitely moved into places and the cable was still connected at the tap. One of them had been vacant for months. There was a filter on it so that it didn't get cable TV but I could get the internet connection on it immediately, since that had to be provisioned on their end anyway.

I'd imagine you'd have to put a filter on it for internet-only customers, no?

Filters aren't really a thing anymore. That was back in the analog TV days. It's all encrypted digital these days. The broadcast channels in your area might be unencrypted but that's it.

The last time I had cable a shitload of it was encrypted and the broadcast channels and some other shit wasn't. You could get it with the digital tuner without the STB.

If everything is encrypted, though, there is no need for a filter OR to disconnect it at the tap.

Do you understand nothing about cable? A modem wont work without service, it wont even work if everything has been hooked up and it's "on" without them provisioning the modem.

Just make the appointment and wait. JFC.

In order for the modem to work, it needs two thing:

  • To be able to communicate with your ISP.
  • Permission from your ISP to operate.

Fixing the cable will allow it to communicate, but unless you have an account with your ISP and they have that particular modem attached to your account, you won't be able to get internet.

OK, hope it works out. I have comcast, and whenever I get a new modem, the only place I can get to at first is comcast.com and their "register your modem" page, where it links the individual modem to my account. Then, it usually takes maybe 5-15 minutes for that to stabilize and I can reach the internet.
