I'm assuming you have Directv since you posted this in a D* forum thread. You can purchase powerline adapters from directv's website. Simply login into your account and select "my equipment" Scroll down and you will see a link for networking, etc. I have purchased 3 of them and they all work great and seamlessly. Also, they have quick turn around delivery time. Ordered one yesterday online and it's scheduled for delivery for tomorrow. Hope this helps.
