Really weird connection problem.

We have three xbox 360s in our home. 2 are connecting without trouble. The third was too but is now doing all sorts of strange things. Sometimes, when testing xbox live connection, it shows it's able to connect with Live. When you back out of that to
the Dashboard, you can see that it's connected to Live. But when you try to login a profile, it won't do it. Other times it won't be able to connect to Live through the test. And it gives various error codes. The most frequent one is about an ICMP problem.
Other times it will say some Live content is unavailable, when in fact it's all unavailable. Nothing about our hardware has changed. Our other 2 360s are having no problems. I updated the firmware on the router (D-Link DIR-655) in an effort to fix the problem,
but still having the same issues. I even plugged in my old 360 wireless N network adapter into the problem console. Didn't fix it. I've been reading for hours, looking up online help both on and off of xbox.com, and nothing has resolved this. Please help.

Hey Larsmorontti and anyone else experiencing an issue! Will you each create your own thread in this forum detailing your experience? The original issue in this thread is related to a service outage which is now resolved so making a new post would be ideal
as it will be easier for us to help you out individually! You can make a new post by following the link here:

Didin't work for me. Still says on my friends friendlist that I'm playing ME3. Tried everything several times, even other profiles and nothing works. Tomorrow I'm to back to PS3 only, not going to buy new Xbox for something they messed up when live went
down....
