ABR-4400 Release Notes

Firmware Version 5.1.1

Note: If you do not need Router Limits content management there is no reason to upgrade your firmware.

Note: Due to the extensive changes made between 4.0.X and 5.0.X, the upgrade process will return your router to factory default settings. Please make note of your configuration or backup your configuration before upgrading. A 4.X.X backup configuration is NOT compatible with the 5.1.1 release. Backup configuration should be used as a reference only.

Note: It is NOT recommended to update the firmware wirelessly as damage to the router may occur.
