Setting up cron job for DD-WRT routers

If you currently have a DD-WRT router and you have a dynamic IP address that changes frequently, you can set up your DD-WRT router to update your IP address automatically.

This cron job will update your IP automatically based on a set interval via wget. First, you would have to find your UUID address as per our link in the instructions below:

What's This UUID?

Then, in your DD-WRT router setup page, go to  Administration > Management and look for Cron.

Make sure  Enable is checked and key in any one of the commands below (depending on the update frequency that you prefer):

30 minutes

*/30 * * * * root wget -qO - [UUID Link]

1 hour

* /1 * * * * root wget -qO - [UUID Link]

2 hour

* /2 * * * * root wget -qO - [UUID Link]

whereby "[UUID Link]" is replaced with the full UUID link.

For example:

*/30 * * * * root wget -qO -

Once that's done, click on  Apply Settings at the bottom of the page and that's it!
