Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point. Press and hold the MODE button while you reconnect power to the access point.Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button. Wait until the access point reboots as indicated by all LEDs
turning green followed by the Status LED blinking green. Then reload the imgae using TFTP.
