Wired multiplayer keeps disconnecting as soon as game starts

Thank you ZsomborFuszenecker.

No worries about the screenshots. All the screenshots are safely stored here - Private Message.

Feel free to check it if you need them.

By the way, if you still have submitted a feedback to Team Xbox please provide the title of the bug and the submission date, you may share it with us.

Regards,

Thanks, its def. not solved, I will follow-up in the other forums if you believe this is not on your table. Feel free to close this if you have no other ideas.

No worries, thanks for confirming. This info would help the Xbox team to look into this, so hopefully there’s some progress soon.

I’m not sure if having the router in bridge mode and having another router in the setup would help in this situation, but it’s certainly a good idea to consider. Everything you’ve tried already though should’ve, theoretically, resolved this.

Also, something I forgot to mention in my previous response - when you report this problem, you may add [Xbox Forums] to the title of the report so it’s easier to find with more visibility, then share this here once complete.

Feel welcome to post back with an update on this anytime.

Hi,

While I have some expertise in advanced network troubleshooting, I’m not really a network expert either. I understand you’ve already tried a lot of possible solutions, so I won’t annoyingly ask you to go through all this again. Just a few questions to help here.

There’s not any outages at the moment as per the Xbox Live Status and on Twitter @XboxSupport

What’s the specific router model? Refer to this guide:

Where is my router model/serial number? - Vodafone Support

Can you confirm:

1. Which Xbox console are you experiencing this error on - Xbox One or Series X|S? Please specify the exact model.
   
2. Are you an Xbox Insider and what OS version are you currently on? You can find this info in Settings > System > Console info. If there’s any pending software updates, be sure to install and apply these.
   
3. Are you disconnected from all online games, or only certain games in particular? And to clarify, are you disconnected from the game servers/matchmaking or Xbox Live itself?
   

You can find the status on recent system updates and known issues here:

What's new: Xbox system updates | Xbox Support

I’m not sure what country/region you’re in, but based on my experience, Vodafone is usually a decent ISP and phone network here in the UK.

Depending on your bundle/plan, I believe they can send you a 4G (or sometimes even 5G) MiFi device as a backup - this is simply a mini portable Wi-Fi device similar to a mobile hotspot. The terms and conditions may vary on this and it would most likely unfortunately only be 4G, but if you do manage to get one of these, then see if there’s an improvement or any difference when your Xbox is connected to this as a temporary workaround. It may help with the extent of these complications, especially as this seems to have started from when your previous ISP moved you over to this one.

Just in case you haven’t already tried this, on their general Help and Support page > Broadband > Speed & connection issues > ‘What should I do if I have broadband problems?‘ they recommend to complete a network performance test if you experience connection drops, slow speeds, etc to identify any significant faults and various reliability issues on the network.

Also, if this only occurs on your Xbox console, please report this problem so the development team can take a closer look with all the diagnostic data.

I would also post to the Vodafone Community Forums where you may receive additional advice regarding this. There are official staff and helpful moderators there as well and if they try to redirect you here, explain that you still have an open thread in Xbox and you’re just looking for other possible options to help resolve this. You can always reach out to support team on Twitter @VodafoneUK (they have separate social media pages for different countries).

It’s generally your ISP’s responsibility to address any issues with your network connection, regardless of how many devices are affected. If this persists, it would be best to contact both Xbox Support and Vodafone Support directly for real-time assistance - select live chat or request a call back. If you get connected to the virtual agent with automated answers, just type in ‘agent’ to actually speak with someone. They should be able to point you in the right direction.

Hope this helps.
