Summary: Dead on arrival like so many others have reported. Don't order this unless your idea of a good time is spending a fruitless evening ruining some poor tech support persons day while you both grow more frustrated.
Summary: I was very dissatisfied with this product and the lack of tech support for it. This router was not a WNDR4500 model and was not certified refurbished. This product is an R4500 which has been reported to be a line made for Costco. It did not work when I received it as the power light continued to blink green and never went steady green, which means corrupted firmware.
Summary: THE PROMOTIONS FOR THIS UNIT SHOULD WARN THAT THE LANGUAGE USED IN ITS SETUP, AND INSTRUCTIONS FOR ITS ONGOING USE ARE NOT WRITTEN IN A LANGUAGE OR APPEAR IN A FORM INTENDED FOR THE CASUAL USER. The "Setup Genie" is a useless, insulting joke. I DO NOT KNOW HOW A PERSON WITHOUT A THOROUGH UNDERSTANDING OF ROUTERS COULD POSSIBLY SET THIS UP AND ACCESS FIRMWARE UPDATES "EASILY" AS SOME MISLEADING FIVE STAR REVIEWS CLAIM.
Summary: This vendor shipped me the Costco model R4500 instead of the WNDR4500 model listed here. It would not even start out of the box due to corrupted firmware. Presumably someone had tried to flash it before and had killed it. I had to google how to manually tftp a R4500 firmware (downloaded from Netgear) onto it using ethernet cable before it would boot. (Google for instructions).
Summary: I cannot get the router to steadily connect to the internet - it keeps hanging up all the time, and I wanted to return it after less than a week of trying to connect (I even managed to update the FW, but it still keeps disconnecting) and get a refund (I even kept the original nylon stickers and everything).
