Flashing third-party devices with Sputnik-Powered DD-WRT Firmware (Web method)
How to flash or upgrade your compatible device with Sputnik-powered DD-WRT firmware using the device's local web interface. We've tested the firmware and flashing process with the following models (for initial flash from vendor-default firmware): Buffalo WHR-HP-G54, Linksys WRT54GL, Netgear WGR614L. We've also tested it as a way to upgrade Sputnik-Powered DD-WRT firmware with all models sold on our web site.
Please note: flashing a device with third-party firmware can damage the device and void the manufacturer's warranty. Sputnik does not support devices that have been flashed by customers.
The web flash method is typically the easiest way to flash your device with Sputnik-powered DD-WRT firmware. However, some devices require that you use TFTP or other methods when upgrading vendor-supplied firmware for the first time. (Instructions for the TFTP flash method appear in other documentation chapters.)
Please note: Sputnik-powered DD-WRT is identical to DD-WRT firmware available directly from its developer, NewMedia-NET, with minor configuration changes: (1) Sputnik Agent is enabled after factory reset, (2) default subnet (LAN/WLAN) is 192.168.180.1, (3) Sputnik logo visible in local web user interface.
Be sure your router is capable of running the Sputnik Agent.
Download Sputnik Agent Firmware from Sputnik's website.
Download Sputnik-Powered DD-WRT firmware.
Log into the device's local web control panel.
Associate with the device (router) either wired or wirelessly.
Browse to the device's web control panel at at its default IP, and log in. Common vendor defaults are:
DD-WRT: http://192.168.1.1, username: root, password: admin
DD-WRT with Sputnik defaults: http://192.168.180.1, username: root, password: admin
Linksys: http://192.168.1.1, username: [leave blank], password: admin
Upgrade the Linksys firmware.
Wait for the firmware update to apply.
IMPORTANT: be sure not to turn off the power or press the reset button on the Sputnik-powered device while the new firmware is loading.
NOTE: if you see a message "Upgrade are failed" (enjoy the grammar), you have hit the router's memory limit. In this case, repeat the above process with DD-WRT mini firmware, and from there, flash again with Sputnik-Powered DD-WRT firmware. You can obtain DD-WRT mini firmware from DD-WRT's web site.
Reset/reboot the router; check to see that the Sputnik Agent is running.
We recommend that you apply a 10-second reset to the rotuer after flashing with DD-WRT firmware. Otherwise vendor settings (NVRAM values) may not all get cleared out resulting in potential instability down the road. To do this, unplug power, hold in the reset button, plug power back in and slowly count to ten.
Reboot the router, and log in at the Sputnik-default address (http://192.168.180.1, root/admin). Click "Status", then "Sputnik Agent". Give the router a few minutes to receive its configuration settings.
"Managed by" should show your SputnikNet ID.
"State" should show "Running normally - Managed". If it does, you're up and running.
NOTE: if "State" shows a different message, refer to the "Troubleshooting" section.
