Can't turn off coxwifi hotspot

Is there a way to disable the coxwifi hotspot? I realize this is not my main network, but I really don't want random people in my neighborhood using my modem's hardware resources. I tried disabling the hotspot in my privacy profile, the modem restarts but the hotspot remains. I know it's not coming from one of my neighbors because it disappears if I unplug the modem.
