Query: Piece of Junk!

Paid like $150 bucks for this thing when it first came out. Drops internet every day with this device. Updated firmware and went through hours of troubleshooting with D-Links horrible customer service. They still would not give me an RMA. They kept wanting me to call them back in a week to check in. I jumped through D-Links hoops many times and they still wouldn't give me an RMA... not doing it again! I explained that I do IT for a living and that in the amount of time I spent on the phone with them I could have paid for 2 of these devices and I was still unable to return mine.
