A:AnswerIf you plug a computer into the Ethernet cable, do you get an internet connection? If yes, then you want to buy a wireless router.
This modem will not be part of a solution if you cannot use coax.
A:AnswerLuke,
You purchased a cable modem. As such, it requires a cable connection using a coax cable. If you do not have a cable line, then I suggest returning the item and looking for a non-cable modem.
