New xBox 360S purchased last of November - used Dec, Jan & Feb. worked perfectly for 10 weeks mostly playing Forza Four online. In the past 10 days to 2 weeks I am increasingly being disconnected from xBox live. Spent late Sunday early Monday 3 hours with online support "Lee" very helpful and patient. There were some Service Alerts when we began but they were resolved - or disappeared as we worked on the problem. Spent 2 hours late Wed early Thursday with Cathy online - also very patient and helpful. Things seemed better but now have returned again.
I am in Knoxville TN. using Comcast Cable with purchased extended bandwidth - consistently tests at 36mbps download and 5.5 mbps upload on speed test.
Modem is Xfinity manufactured by SMC new 4 months ago when telephone service was added. Has 4 Ethernet Jacks for direct wired connection. Is in bridged mode for use with my DLINK DIR 855 Gigabyte Router for my wireless units. Laptop and BluRay Sony wireless DVD - online movie player.
I have been able to use the wired connection from the xBox 360S to the DLINK Router but not directly to the Xfinity Modem. I can also get connected going wireless. But both are subject to disconnection. It starts sporadically but increases as time online passes. It happens in the middle of online races on Forza Four.
I moved the xBox close to the router and modem to use shorter ethernet cables and I've tried at least 6 - 2 brand new.
The Console MAC address is 6045BD2C5171. but when I try to connect direct to the modem I get IP Address Error.
I tried entering the DNS addresses manually 126.96.36.199 and second line 188.8.131.52 that still did not work.
The Status numbers found using the Y button on the controller are.
W. 0000 000B
X. 4000 1001
Y 0000 0000
z 0000 0000

A 0.0.0.0/0.0.0.0 and were prior to that 169.254.141.25/255.255.0.0 which should be the IP Address/subnet mask I think
D: 184.108.40.206/ 220.127.116.11
I do not understand why the wired connection works - but then begins to disconnect increasingly through the DLink Router as also happens using the Wireless network
and I don't understand why I cannot bypass the router and connect directly through the Modem. The Techs at Comcast don't believe there is anything that should preclude use of the Xbox through their modem directly - I have tried at least 3 of the four jacks that work with other devices and I've tried different cables.
I will be glad to provide any other information I can in order to stop this problem that is making it increasingly difficult for me to enjoy my games and has cost me at least 10 hours of TECH TIME with some very nice support people at xBox and Comcast. - Still I would prefer having that time to race and play if at all possible since I'm actually paying a significant part of my retirement income for the privilege. Can you help me please?
