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

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.

i have problems with virgin media in the UK over wifi (using their superhub 2). Kicks me off fifa pretty much every game. Only way around it is to connect using wired. I'm hoping the problems are linked and any patch will sort that out too!

or you could just not use the Junk gateway devices that Comcast gives out... put it into bridge mode and use your own wifi with no issues at all... I can't stand those all in one gateways, they are pretty much junk firmware wise... and their signal is really low power

When I first got my Xbox One and connected via my WiFi the Xbox said I had a DNS problem. I was using my local ISP's DNS server and simply changed it to Google's public DNS 8.8.8.8 and this fixed my issue.

Not saying this is the same problem being reported.... I just found it interesting. My ISP is a small local ISP and I reported the problem to their CEO. I have fiber straight to my house.

I always use 8.8.8.8 as primary and Comcast DNS as secondary.

Why? Comcast's DNS runs on DNSSEC servers which are more secure, and Comcast has it set up so you always connect to one that is the closest rout to your location and they are usually a lot faster then 3rd party ones

I don't use Comcast, but back when I used Cox, their DNS servers were horribly over loaded. I used a local caching server instead. I don't think that's related to this wifi issue.

Comcast DNS has issues resolving some domains randomly. No one has time for that so I usually just default to Google's DNS with OpenDNS as a secondary and the ISP for tertiary.

I've never had an issue with Comcast DNS resolving... only time I've seen anyone with issues was when their Name servers were also DNSSEC and their certs expired or were revoked

On rare occasions it has happened and to be honest whatever issues were there are probably fixed by now but techs have a habit for holding grudges.

I have had no problems with my X1 connecting wirelessly using a Comcast Modem with my Netgear Router. However, I upgraded my Comcast service today to include their home security package and the modem/router had wireless integrated. Now, I am having issues with COD-Ghost. Therefore, I am going to set my Netgear back up for wireless and see if the issue goes away.

Why does MS have to release a patch. This is a Comcast issue. If you turn off the Comcast wifi (in the router) and hook up any $30 Linksys wifi router the issue doesn't happen. So if a $30 router fixes the issue on the same Comcast internet its not MS its Comcast.

Given this might be impacting only Xbox One devices I suspect it is a lot easier for MS to identify/code/release a console-side automatic update for the small (in relation to total subscribers) population of Comcast users affected than it is for Comcast to try and release a fix for their gear. Sometimes the path of lease resistance is easier than a much longer wait to get the 'better' fix in at the appropriate level. Comcast could eventually release an update of their own for their gear that cleans it up later for all subscribers.

It's rather unspecific what the problem is, but I also had constant problems with roku and a linksys router over wifi. It finally went away when I got the Verizon FIOS router. I suspect it's specific chipsets that conflict. Hard wired is the way to go for games and streaming if you can run the wire.

Not sure if it's a Comcast issue if other devices can connect OK. I agree hard wired is good for playing online but if you just want to download games, stream videos, and get update patches, then you should be able to use WiFi. Not everyone can run cable all over, and some just prefer the aesthetics over functionality. Some people want their router near the PC and not the TV.

I would use Ethernet personally, or worst case power line LAN w/VPN (in case of leakage). Too bad for the WiFi users though, hope it gets sorted.

Dang!

That sounds EXACTLY like what I'd say about Charter!!

Seems the most logical, maybe?
