A:Answer Yes, this will work with any broadband Internet service. For Spectrum, you just connect it to the wired Ethernet port on the "cable modem" they supply to you. If you are also paying Spectrum for wifi, they use two different setups. One is where they supply a cable modem and a separate Spectrum-owned wifi router. In that case, disconnect the Spectrum wifi router and use this in its place. You can return their wifi router and save a monthly rental fee on it. Some setups will use an all-in-one cable modem and wifi router. In that case, there should still be an Ethernet port where you can connect this router. Note that in this case, Spectrum may still charge you an extra monthly fee for their wifi router. If that is what you have, you may want to contact Spectrum about swapping that all-in-one device for a simple cable modem and save the additional monthly fee for their wifi.
