Weird question, I know. My apartment comes with a modern/router combo that, for whatever reason, does not have an Ethernet port. So a friend advised me to purchase a modem, then connect it via coax cable to my apartment’s modem/router, then connect that to my PC via cat5. I did so, but the Ethernet connection on my PC shows no Internet. Is this possible to set up? Is there a software related step I’m missing to complete the connections?
Call your ISP, they can tell you if your modem is supported, and they will need to allow it to connect. It will be possible if they allow it.
Wow that should've been obvious, don't know how I didn't think of that. I called, they said it's not possible as it's not in the contract with the property. Thanks!
If you're in Europe, you can try arguing they are in violation of the EU open internet regulation, but it's unlikely to get you anywhere if you're not in the green-marked countries of the map below: https://fsfe.org/activities/routers/routers.en.html
Yeah in my experience most ISPs will not allow this without paying for two accounts. You may be able to get them to provide a different model modem/router, you are likely already paying a rental fee for the one you have. Otherwise they can give you a list of the types they accept and you’re just going to have to buy one to sub in. Unfortunately the combo models tend to be on the pricey side.
