I have some tennants who inhabit the downstairs part of my house who torrent practically all day. I would like to kick them off the router but they have their own router they use as a bridge which is plugged into my own router, i would move the router to the upstairs portion of my house but my router requires a working phone line and none of the ones upstairs work and it costs too much to get them fixed. my router is a CG3000v2. Does anyone know how i can solve my problem. (no i cant just unplug their router)
