Another 80151904 request

Hello.

I have seen many posts about this, and I have seen a lot of advice, but none of the suggestions have worked so far.

The scenario:

My xbox 360 has worked fine for years. I have lived at the same location, with the same isp, and with no issues. Approximately 1 week ago I got disconnected from a game (mass effect 3 multiplayer if that matters) and have not been able to sign in again
while at my home. I get this error code everytime. The two things that confuse me the most are:

1) My Roommate also has an xbox 360 that has used the same connection as me for quite some time (at least a year) with no problems. He is not experiencing this issue, even though we are literally using the same router.

2) as a test I have taken my xbox to a different location, and it connects just fine. It is only my house, but it's also only my xbox. All other consoles / devices are fine.

Things I have tried:

Power cycling modem

Power cycling router

Clearing cache

Deleting/re downloading my profile

Connecting directly to the modem instead of via router

Using different ethernet cables

I'm at a loss as to what to do next.

Answers to questions from connection trouble shooting post:

I'm from chicago, il, United States

My modem is a Motorola surf board model SB5120

My router is a Cisco linksys E2500

My connection is wired

Upnp status is unknown

I am not aware of any NAT errors and have never had one

The error code is always 80151904

My ISP is comcast

The values after running a connection test are as follows:

W: 0000 - 000B

X: 4000 - 1001

Y: 0000 - 0000

Z: 0000 - 0000

ID: 0001 - 0002

L: 0015 - 10F1

Q: 8007 - 0435

A: 169.254.211.83/255.255.0.0

G: 0.0.0.0

If you need any other information from me to help with the problem, please let me. Any assistance is greatly appreciated. Thank you for your time.

Yet ANOTHER Request!!!!

hey sure greens I haven't tried siege and all that ben playing mercs

 

on
support.xbox.com/.../error-code-lookup please check your error code 80151904

it indicates there is something wrong with your Profile data and provides a possible solution

but a: 169.254.211.83

your xbox states it did not recieve a correct ip address with automatic Settings.

you could give it a try with Manual Settings, just check on your roomates xbox which ip address this one is using (usually 192.168.***.***). for the ip address the last block has to be different, the 3 others have to be identical, every other entry should
be identical: subnet, Gateway, dns servers
