This product was expensive but one of the cheaper Mesh Wi-Fi Systems available, I got it and actually found the setup quite difficult. I would recommend calling D-LINK's 24/7 tech support number on the box of this product if you are having troubles, sooner rather than later. I stubbornly spent too long trying to figure out what the problem was, once I was on the phone with them it took about 10 minutes. Once set up, this product reached the dead spots in our townhouse and has been working great with our NBN.
