Ensuring that Sputnik Agent can communicate with SputnikNet over a device's WAN port
How to set the DD-WRT Keep Alive function so that the WAN port is open for the Sputnik Agent.
Enable DD-WRT Keep Alive.
In some versions of DD-WRT firmware, the Sputnik Agent, once enabled, can attempt to reach Sputnik Instant Setup or its assigned SputnikNet server before the WAN port becomes active. If this happens, the Sputnik Agent has no way to make a successful connection, and will eventually time out. This can significantly slow down the provisioning process.
Here's how to ensure the WAN port is opened first, and speed up provisioning. For non-Sputnik default DD-WRT firmware, take these steps before enabling the Sputnik Agent.
Browse to the DD-WRT administrative interface (if using Sputnik defaults, http://192.168.180.1; otherwise http://192.168.190.1 if stock DD-WRT).
Select "Administration/Keep Alive".
Click "Enable" under "WDS/Connection Watchdog".
Set the interval to 900 seconds.
Set the IP Address to the server domain of the SputnikNet server you are on, e.g. scc22.wifi.sputnik.com. (Do not enter your specific account name, just the server URL).
Click "Apply Settings".
