If you do not require any wiring or are opting to save money by choosing Spectrum’s $10 self-installation option, you simply have to connect one end of a coaxial cable to a cable outlet and connect the other end to your Spectrum modem. You then wait for the modem to connect to Spectrum’s network, which takes roughly two to five minutes. Once live, you are able to connect your computer or your Wi-Fi router to the modem.
