I cant figure out why this thing is so bad. I first bought this from BestBuy for $160 and had it for like two weeks, then i found out it was on Amazon for a lot cheaper, so i returned it and ordered it on Amazon. The first time i got it i was excited to get the latest and most advance modem/router available, but having experience non-stop problems with it i became very irritated. it would disconnect after every 10 or 15 min or so for NO REASON!!! Not only that, it was freaking slow and the connection was unreliable. It would take like a whole minute just to load up Yahoo and then when you run a speed test it would give me 15mb/s which is what i pay for. I do not recommend this router for anyone unless they like being stressed all the time. Instead i bought a regular DOCSIS 2.0 Motorola modem and a TrendNet dual band router which is soooo much better and faster and reliable and easier to configure than before. Just stick to the basics because the more complex it is the more problems you'll have.
