Q: Do you need a coax cable for internet? If you have cable internet, then yes, you do need a coax (or coaxial) cable to connect to the internet. Your internet provider should give you one with your modem, but if you're missing one, you can find them for pretty cheap on Amazon.
Connect one end of your coax cable to your Modem and the other end to your cable outlet. Connect the power cord to your Modem and plug the other end to the electrical outlet. Wait for the Modem to connect to the network. When the 'Online Status' light is solid, that means it's connected.
Does spectrum need coax?
If you're installing both Spectrum TV and internet, you'll need to attach a coax cable to your outlet, then attach the coax splitter to the free end of the coax cable. ... But when you're installing only TV, you probably won't need a cable splitter—unless you want to mirror your channels on other screens in your house.
