Cuch, the controls you seek are probably on a web page hosted by the wireless base station. You can usually reach it by going to http://192.168.1.1
or something like that (the last digit of the IP address might be something else depending on how your network is configured). If in doubt, do a traceroute on any packet going through the wireless basestation and it's address should be one of the first hops. At the base station's "web site" you will find a set of pages that let you configure the wireless router. If it asks you for a password and you don't know it (and have never changed it), then do a bit of googling for the factory default password (and change that password becasue in it's default state, your 7 ft neighbor can log in to your basestation for fun and profit!!!).
