Query: Returned Product

I had to return this product as it did not work. I was on the phone with D-Link Tech support for over an hour and they could not help me. Ultimately I had to return the product, and I will say, Amazon's return system is AWESOME. I printed the return label, mailed it off, and had my account credited the next week. Meanwhile, I bought another product from Amazon and it works great.
