Comcast said it is working with Microsoft on a “software issue” that is causing issues for some Xbox One users who are trying to play games online via WiFi networks that that utilize IPv6 addresses.
“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,” Comcast noted in a post to its IPv6 Information Center on December 17.
Comcast’s Jason Livingood posted a similar message on the DSL Reports message board on that date, noting in a later thread that the effect of the software problem is a "hit or miss" scenario depending on the game title.
As an immediate workaround, Comcast is recommending that users connect their Xbox One consoles 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,” Comcast added.
It was not immediately clear how many Xbox One users who are also Comcast broadband customers are subject to this potential software-related issue. On December 11, Microsoft said it had sold 2 million Xbox consoles since its launch on November 22.
Comcast, meanwhile, has been out in front with its IPv6 transition as the pool of available IPv4 addresses continues to run dry. Last month, Comcast said it had deployed native IPv6 support to more than 75% of its broadband network, making it the world’s largest. At the time, the MSO, which leapt past AT&T and KDDI of Japan, said it was on pace to complete the v6 deployment by early 2014.
In May, the American Registry for Internet Numbers (ARIN), which manages Internet number resources for the U.S., Canada, and many Caribbean and North Atlantic islands, told Multichannel News (subscription required) that the burn rate for v4 addresses was accelerating, confirming that full depletion could occur before the end of 2013.
