I own a NETGEAR N600 Dual Band router: model WNDR3400.
We've had this router for 2 years now, it works fine. But sometimes, every year since we've owned it, the internet has either went down for a day, or occasionally even the router. We have Comcast XFINITY double play. We get 25-27mbps download, and a 3.4-5 upload speed.
We got this router because me and my brother play XBOX and PS3 at the same time online, while our parents stream videos online. My iPhone 4S once every two months will randomly pick up the signal for 5 seconds, drop it. This will go on for 2 days.
We reset it once every 3 weeks. Once, we changed the security password and it ran fine for 3 months.
Lately, the speed has been slowing down drastically!
