Thank you for posting and I am sorry to hear your power supply is no longer working. In order to receive a new power adapter, you can call our support line at 1-866-347-3292 and have them send a new one out. I can also do this for you here as well, after a few details. If you would like me to send one out to you, please let me know if you are requesting a power supply for your HughesNet modem or for your own third-party device. Also, did the power supply fail after reaching its life cycle or was it damaged?
