Upgrade Firmware

By default upgrading your firmware will completely erase your current configuration. It is strongly recommended that you back up your current configuration before performing an upgrade.

You can attempt to preserve your old settings by ticking Attempt to Preserve Settings below. Be aware that this can potentially lead to problems if the new version is significantly newer than the old version, but for small, incremental differences this will likely work. It is always best to keep a backup just in case.
