I have a Netgear model WGR614 wireless router in my house. It is connected to a broadband modem. I'd like to know how I can block, disconnect, or disable service to the computers and devices that get service thru the router at my choosing. I pay the bills for our broadband service. My brother who lives here also, contributes zero to the bill yet brings his friends over and with all their devices(xbox, playtation, laptops, ipod, etc....) taking up the bandwidth. I am the router 'admin' and can see it through my computer by going to 'routerlogin.net' and I can see all the attached devices at any given time. I'd like to be able to disconnect them at will when I need the bandwidth. Any ideas would be appreciated!
