One of the cool features found in many SOHO wireless router firmwares now a days is the ability to broadcast a guest network. This guest network allows people who are visiting your home or small office to connect to the Internet while at the same time preventing direct connections to the other computers on your network. However, I found it also useful to be able to toggle this guest network on and off depending if I have visitors or not. The following scripts can be customized to run from a Linux or Mac platform to provide a quick and easy way to turn this feature on and off.
Script to activate the guest network. The osascript command is optional and used to display an alert for MacOS X systems.

SSID=<NAME OF GUEST NETWORK>
PWD=<PASSWORD TO CONNECT HERE>

osascript -e 'display notification "Turning '$SSID' on with password '$PWD'" with title "Activating Guest Network"'
Script to deactivate the guest network.

osascript -e 'display notification "Turning '$SSID' off" with title "Shutting Down Guest Network"'
To make these scripts executable by double clicking on the MacOS X platform, open up the AppleScript Editor and save the following as applications.
