‘m using a Cisco Linksys WAG320N Router to connect my OS X UNIX and Linux systems to the Web. How do I reboot my Linksys WAG series router / gateway (modem) from UNIX / Linux / OS X bash command prompt or using a shell script?
The Cisco linksys series modem removed reboot option from its web interface but you can reboot the router using the following url format:
http://your-router-ip/setup.cgi?todo=reboot http://192.168.1.1/setup.cgi?todo=reboot
Sample outputs:

The web interface hack works with any web browser regardless of the operating system.
