So we just bought a house and we had to switch from a using fiber to a cable company, and the router the cable company provided has almost no range at all. I tried changing the channel and that helped a little, but what what i'm trying to do is use my cable modem/router (cisco cp3825) as just the modem and use my other modem/router (Motorolla NVG510) as just the router. Does anyone here know if this is possible?
