So reviewing the DIR-815 router settings and having multiple game consoles on his system, The 815 doesn't provide IMO, enough QoS options to effect proper configuration of the router for the game consoles to connect well on XBL. This 815 would be good if only he had one. I recommended getting into a DIR-825 or a DGL-4500 for his gaming needs as these would provide better QoS options for gaming on XBL. I'm waiting on him to reply back when he gets the different router in house. 
His Apology was accepted. 
You da man Furry! What people don't understand is there is a couple of people out here that give their personal time to help with D-Link equip. Before you and one or two others came along, there was nothing but people with problems saying they would NEVER buy D-Link again! Here I am using my Dir-825 to the fullest, IPV4, IPV6, all kind of goodies, no problems. The couple of question I had went unanswered untill I got time to try several fixes out myself, no help from D-Link or this forum, untill you came along (did get some help from users of the 655 forum untill I upgraded to the 825)
Hats off to you Sir, for one you have much more patience then I do.
