Query: Faulty, frustrating disaster

Bought this router early July, set up was relatively easy and straightforward (I've set up many routers and home networks before, though).Every 4-5 hours we will lose our internet connection for anywhere from 30 seconds to 3 minutes. Then it will magically come back up.As of this moment, I have called tech support seven (7) times now - each time they had me change a different setting. Why wouldn't they just have me change all those settings right off the bat?Irritating and illogical.It doesn't matter though, because even after approx. 3 hours time spent with D-link tech support, my router still does not function as it should - I still get extremely slow and/or intermittent connections every 4-6 hours. Completely unacceptable. I will be returning this P.O.S. for a refund ASAP.
