Customizing your home router with OpenWrt

Backing Up

OpenWrt is a system that really invites users to experiment. To make sure you can restore a working system if disaster does strike, various methods of backing up the configuration files and partitions are available below System | Backup & Restore.


If you can't get the machine to talk to you in the normal way, pressing the reset button might be your only option. Hold down the reset button at the rear of the device for 30 seconds, then continue holding down the button while you unplug the power connection and for another 20 seconds after unplugging. When you reconnect the power supply, the DMZ LED lights up to indicate that the router is now in maintenance mode and that your settings have been reset.


To restore the original software, first download the manufacturer's image file [7]. Then go to System | Upgrade in the GUI and click on Find… next to Firmware file:. In the file browser, select the image you downloaded and then click Open. Finally, click Upgrade to reinstall the original firmware.
