This unit worked. However, the connection speed was about 1/20th of what I had before. I read through the forums and tried several things to get the speed where it was supposed to be but nothing worked. I did end up calling D-Links customer service (great service by the way) and they were able to walk me through several steps of what to try. Nothing worked to get the speed to where it is supposed to be. I am not sure if it is compatibility with Frontier (used to be Verizon) Fios (Fiber Optic) or if the device was faulty. I am sure this would be a great product had it worked with my network. I ended up returning it for a refund. I did contact Frontier for a list of compatible routers and they ended up sending out a free replacement router, which worked.If there were additional ratings for the following:Vendor's (D-Link) customer service: 5 StarEase of return: 5 Star
