Thought I would post my experiences so far,
Been very good for where the router is actually place back on one side of the house in a corner office room.
Have 2 xboxes, 1 wired and 1 on a 5Ghz DAP-1533 wired AP to the 655. Using XBL Gaming and QoS sticky information, Gaming was great, full green bars in BO2. Only 1 or 2 games were signal was Yellow and probably due to other probable player issues.
Router is behaving well and seems very stable.
Signal is good however on 2.4Ghz my iPhone was not getting great signal however distance and placement of router is playing a role in that. If if move the router back into the living room from opposite from where office is, well, signal wouldn't be an issue.
Over all, v2.11NA is good other wise.
Enjoy everyone.
Thank you D-Link.
