MTU for XBOX live mutliplayer gaming on 5g home broadband

[Lexx289]

I am struggling to get my Xbox to work on Xbox live. Doing some googling it seems that the MTU is too low, it is 1360 and should be about 1385 to be able to work properly. I have rung three who seem to have no knowledge of what an MTU is and have sent me to the ombudsman. I have logged into the router (H122-373) and increased the MTU manually however it will not pull through onto my XBOX. I have put it in the DMZ, enabled UPNP and generally faffed with it as much as i can but the MTU on the XBOX does not change. I am assuming this is what is being sent from three and so it is something to be changed at three's end...

Does anyone else have any experience of this, or have any issues with XBOX live and home broadband 5g? or can they get it to work, cheers

Has anyone found a work around for this? My speeds for the Xbox are perfect but I'm having this same MTU issue. Some people are reporting changing the MTU on their router? I couldn't find how to (if that works) but just seems to be a more common issue. 

I've tried using wireless and wired connection and still having the same result. My MTU is also 1360.

@JonathanB as you can see even more people are now suffering the same issue. Surely it shouldn’t take this long for 3 to fix this issue/provide you an update you can share with us regarding the problem? It’s been quite a few weeks now and other people are now raising the same issue!

[MrSimo98]

I totally agree. It's such a pain. I managed to find the MTU feature in my router today with help from another Three forum member. Mine was automatically set to 1500 so it's strange to why the Xbox is at 1360.

Have you been able to fix the issue? 

May cancel my direct debit if this doesn't get addressed 

[MrSimo98]

Sadly no, we are all in the same boat. I wouldn't be to hasty cancelling your direct debit though, this can go against you on your credit rating.

Having the same issues with FIFA 23 on Series S, really frustrating soon as I get into a game after a minute the game freezes and I get the loss. 

Please get this issues addressed
