Xbox One Update

On February 15, 2014, Microsoft released a mandatory system update for the Xbox One that also addresses an issue impacting multiplayer gaming over Wi-Fi.  Specifically the Xbox One issue affected Arris XB2 (TG852/TG862) integrated wireless gateways being used in areas that support IPv6 enabled broadband.   Xbox One consoles not using WiFi, or other Comcast Gateways or service areas were not affected.  For more information about the patch please visit Xbox One operating system versions.  Comcast and Microsoft have collaborated closely since this issue was discovered and are happy to report that this issue has been resolved.

Xbox One Service Advisory

Comcast and Microsoft are aware of a software issue affecting the ability of Xbox One users to play some games online. This issue is only observed when the Xbox One is connected to a network via WiFi and when that network also has an IPv6 address. In those conditions online gameplay for some titles may not work.

To immediately solve this issue, we recommend that customers connect their Xbox One using an Ethernet cable instead of WiFi. Comcast and Microsoft are working together to further diagnose the issue and we anticipate that Microsoft will release a software update after the holidays that will resolve this issue.
