The Fon heartbeat

This is the way to simulate the fon heartbeat, so that the LaFonera with dd-wrt is shown as active on the fon maps.

It is based on the work of freddy (http://fon.freddy.eu.org), futejia (http://futejia.blogspot.com) and krikkit (http://www.krikkit.net)


At first you have to register your LaFonera on www.fon.com

If you have done this successfully there are two ways you can enable it on maps.fon.com.

Fast and simple

This is the most easy way (This guide is also available on http://www.wildblue.de/fonera/heartbeat/howto). It is for simply putting your LaFonera on maps.fon.com without any need to set up your own WEBserver / FTPserver.


PLEASE NOTE: The following heartbeat script only runs once an hour. FON have recently changed their system to recognise heartbeats once every half hour, so this script will leave you seemingly unactive 50% of the time. To fix, simthefon needs both occurences of "3600" changing to "1800". I'll notify wildblue of this but for now, either put up with it or wget an edited copy from your own server.

Actual Version: 2.0.3

Feel free to ask me for an update of the code.


  1. Open the web-based configuration on your DD-WRT-Fonera (e.g. 192.168.1.1)
  2. Go to the "Administration" section, then to "Commands" (German: "Diagnose")
  3. paste the follwing commands and select "Save Startup" (German: "Startup speichern")
