The backup is available through LuCI rather than the main GL.iNet interface:
- Open System → Advanced Settings.
- Enter LuCI, then open System → Backup / Flash Firmware.
- Under Backup / Restore, select Generate archive.
See the forum guide: How to Export/Import Backup Configuration Files via LuCI. Keep the archive securely because it may contain sensitive configuration. Restoring a 4.9.2 backup onto 4.11 beta is not guaranteed to be compatible, so separately record your DHCP reservations and other important settings.
Under System → Upgrade → Online Upgrade, enable Accept Preview Plan to receive preview releases offered for your model. If the switch is absent, disabled, or beta 3 is not offered after enabling it, install the GL-BE14000 beta through Local Upgrade instead; participation in the preview plan does not guarantee that every beta build will be available online.
