you need to recover the firmware.

a static IP address from 192.168.1.2 ~192.168.1.254.
3 Use an FTP client on your computer to connect to the UAG. For example, in the Windows command
prompt, type ftp 192.168.1.1. Keep the console session connected in order to see when the
firmware recovery finishes.
