Some Comcast customers can't connect their Xbox One to the Internet via Wi-Fi


May 4, 2013
While some new Xbox One owners use a wired Ethernet connection, it's more likely that they take advantage of the console's Wi-Fi hardware to connect the unit to the Internet. Now it appears that some some Comcast owners are unable to play online games on the console, thank to a particular network problem that both Comcast and Microsoft are currently trying to solve.

DSLReports has a statement from Comcast's Internet & Communications Engineering division Jason Livingood, who wrote:
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.

The bug does not come up when the Xbox One has a physical Ethernet connection to Comcast's broadband service. Livingood stated that both companies are working together to fix this problem and that he anticipates Microsoft will release a software patch for the console in the near future that will hopefully solve this issue. There's no word on if this bug is affecting non-Comcast customers.
