Reboot Linksys WAG160N / WAG54 / WAG320 / WAG120N Router / Gateway

Posted on in Categories , last updated August 25, 2010

I‘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.

  1. I had to use this on a SPA400
    username of Admin and no password, and the different path in the URL.

    curl -u ‘Admin:’ ‘http://10.56.272.56/html/setup.cgi?todo=reboot’

  2. Thanks It works perfectly on windows ;)
    just change ‘ to ”

    curl -u “username:password” “http://192.168.1.1/setup.cgi?todo=reboot”

  3. Hi, I’m trying to do the same thing with 2 WRVS4400N in to different locations, But CURL says ‘Authorization required.’
