I purchased this new. Sold for $600 at BestBuy. I upgraded from cable internet to fiber and wanted to upgrade my router also. Unfortunately it does not recognize my firesticks and I'm too old and not savvy enough to figure out the upgrades and whatever it takes. Too poor to pay someone knowledgeable of networking. Great router. Hooked up and never used came factory wrapped. Still have all the factory packaging. Save $425 and go home happy. I may cry though. thanks for looking
