Cant connect to WN2000RPT

are any other lights on? 

have you tried a 30/30/30 reset? Push and hold reset for 30 seconds while powered on, power it down and continue to hold reset for 30 seconds, power it back on while still holding reset for 30 more seconds? Don't let off the reset during any of the period. 

Try that first. 
if that doesn't work, then you might have a corrupt firmware issue. You could try tftp/nmrpflash to recover it. 

 are you on windows? if so, follow this guide
