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.
