The backup and restore page consolidates the most impactful router operations in one place. Use it to protect your configuration before making changes, recover from a bad state, or update the router’s firmware. Each operation interacts directly with the router over SSH. Navigate to /router4/copia to access this page.

​
Download a configuration backup

A backup captures the current UCI configuration as a compressed archive you can store locally and restore later.
1

Click Download backup

The application instructs the router to create the archive:
sysupgrade -b /tmp/backup.tar.gz
2

Receive the file

If the archive is created successfully, it streams to your browser as a download named backup_router_YYYY-MM-DD_H-i-s.tar.gz. The temporary file is removed from the router after transfer.
Download a backup before changing SSH settings, firewall rules, or applying firmware updates so you can recover quickly if something goes wrong.

​
Restore from a backup

1

Select your backup file

Click Choose file and select a .gz or .tar.gz backup archive. The maximum file size is 10 MB.
2

Upload and restore

The application transfers the file to the router via SCP:
scp backup.tar.gz root@192.168.10.1:/tmp/restore.tar.gz
Then runs the restore command:
sysupgrade -r /tmp/restore.tar.gz
3

Wait for the router to apply settings

The router applies the restored configuration. Depending on what changed, services may restart automatically.

​
Factory reset

A factory reset erases all configuration and returns the router to its out-of-box state.
Factory reset is irreversible. All UCI configuration, network settings, SSH keys, and custom scripts will be erased. Download a backup before proceeding. The router will reboot and will not be reachable at its current IP address until reconfigured.
1

Check the confirmation box

The factory reset button is disabled until you explicitly confirm your intent.
2

Click Factory reset

With confirmation, the application runs:
firstboot -y && reboot
The router immediately begins its reset and reboot sequence.

​
Flash new firmware

Flashing firmware replaces the router’s operating system image. The router reboots automatically when flashing completes.
Do not close the browser or interrupt the connection while firmware is being transferred and written. A failed flash mid-write can render the router unbootable. The router will reboot automatically when flashing is done — this is expected behavior.
1

Obtain a compatible firmware image

Download a .bin firmware image for your specific router model from the OpenWrt downloads page or your hardware vendor. Using an incompatible image can brick the device.
2

Select the firmware file

Click Choose file and select your .bin file. The maximum file size is 20 MB.
3

Upload and flash

The application transfers the firmware to the router via SCP:
scp firmware.bin root@192.168.10.1:/tmp/firmware.bin
Then starts the flash:
sysupgrade /tmp/firmware.bin
4

Wait for the router to reboot

The router will reboot into the new firmware. Wait 2–3 minutes before attempting to reconnect. If the router does not come back online, it may need recovery via a serial console or TFTP.
By default, sysupgrade attempts to preserve configuration when flashing. If you want a clean install, run a factory reset after the firmware update.
