I have a wireless Cisco IPN330HD receiver that I move from one place to another. The power supply is mounted in an awkward position and is not easily moved. I would like to purchase a second power supply to be able the move the receiver more easily. The part number on the power supply is OEM ADS0202 but, I am having a hard time finding one. I called ATT(Uverse) and they cannot sell me just the power supply. Does anyone know where I can get a second power supply for the receiver?
