Comcast: Dropped XBL Connections Connecting Through Wi-Fi Repeater

Comcast (ISPs): Dropped XBL Connections Connecting Through Wi-Fi Repeater
It's most likely an issue with the wireless signal. You could try hard resetting the Xbox and rebooting all of your networking equipment to see if that helps. If you're able to connect to a different Wifi connection without any issue it's either the
Hub or the Repeater. If you're able to, try connecting to the Comcast Hub (even temporarily) and see if it works fine. If it does, it's likely the repeater causing an issue.

Any hope for those that Can't Get Teredo IP Address?

Comcast has issued a bulletin in regards to the issues and they say to use a wired connection instead of wireless until it is resolved.

If you go into the settings menu and go to network settings and run a network test and it comes back as fine then there isn't much that can be done.
