Log into the local DD-WRT web interface on the Sputnik-Powered device. By default, login at http://192.168.180.1 with username root, password admin. Those values can be changed (and for security purposes, its important to change the password).

Select "Status/Sputnik Agent".

"Managed by" should show your SputnikNet ID.

"State" should show "Running normally - Managed". If it does, you're up and running. If not, review the error messages below.

Check WAN port connectivity. You're not connected to the Internet. The WAN IP address, shown in the upper right hand side of the screen, will show 0:0:0:0.

Check DNS (domain name services) settings. If your device connects via DHCP, the upstream DHCP server isn't providing valid DNS server IP addresses. If it connects via static IP, configure valid DNS server IP addresses.

To access your device's DNS settings in the DD-WRT web interface, select "Setup/Basic Setup" and look under "WAN Setup" at the top of the page.

Make sure your upstream firewall isn't blocking high-numbered ports. Port forwarding is not required.

The AP initially connects with SputnikNet over port 5222. This port must be open, outbound, and almost always is. The AP and SputnikNet then choose a random, high-numbered port for ongoing communications. These are sometimes blocked by upstream firewalls.

To test that communications between an AP and SputnikNet are working, open a terminal from a PC connected to the Internet  through the AP or through the same WAN connection that the AP is using.

At the prompt, type:

telnet wifi.sputnik.com 5222

You should see a response similar to:

Trying 206.223.158.30

Connected to wifi.sputnik.com

Escape character is '^]'.

If you do not see this, then you need to open high-numbered ports on the upstream firewall.
