If you are interested in a D-link product, be aware that their customer service has been non existant.I switched to their 655 wireless router based on some positive reviews and is disconnecting with this message"The gateway is currently measuring your network connection.Accessing this web page might have an effect on the measurement.This page will refresh shortly."I checked that I have the latest firware and changed settings multiple times.Contacted the tech support team twice and still waiting for a reply.

Keep trying. They all have a limited time to give you support and if they don't respect it, they may get sued. I would try older firmwares, though.
