[myamaung]

Can't read, no connection at all. I turned the power off and turn back on Extender was start blink all lights and no boot up at all. Even though can't reset to factory default. Could some one explain me how to reset please? I can't update the firmware now. Help me please. Thanks advance,

to factory reset, push and hold the reset button while its powered on. Hold it for up to 30 seconds. 

then let it boot up. It might take a couple minutes. 

Did that work? 

If not, you might have corrupt firmware. you can try recovering it via tftp. 

are you on windows? if so, follow this guide
