Why is a Spectrum router needed with the modem?
So, I recently upgraded to Ultra and the technician came to install the new cable modem and router. The previous modem had a router built in. I told the technician that I don't need a router as I had my own.
However, the service did not work. I checked my hooking my computer directly into the cable modem.
Finally, the technician installed the Spectrum router and the service worked. My question is why is the router necessary for internet service? Shouldn't the cable modem by itself be sufficient?
