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

I have been having this issue for over 6 weeks. MTU size does not change and also when you enable UPnP it doesn't actually do anything and it will not make use of IPV6 either. I am loosing access to most online Xbox games, it gets worse every week. We need a different capable router sending out.  Last night it struggled with youtube.

Hi Jonathan, Maybe the next step is to borrow a router or two or more different types and connect to your own Xbox? This would highlight issues with the router if the problem arises.

I have just tried a similar test using a hotspot, I am not using the three network for this and sadly it's only 4G suppose to 5G which in this instance is probably good for the test. Upon testing my hotspot I too get an MTU of 1480. 

What I have noticed differently connecting to my phones hotspot supposed to the Three 5G router both wireless and wired is when I go to the Xbox Settings - General - Network settings - Over to the right hand side under "Current Network Status" the Xbox is connecting to both IPv4 and IPv6 using my phones hotspot. Once connected to the router IPv6 disappears. If I go into the Advanced Settings on the Network tab on the Xbox it tells me that the Port connected is using Ipv4. Read about using IPv6. 

This might be a long shot, but this is the only difference I can notice.

Hi, I keep getting MTU errors on my xbox one. I’ve tired everything from changing setting on router and phoning three but they don’t seem to know what I’m talking about. 

The minimum requirements for the xbox MTU is 1384 but I can only seem to get 1360. I’ve added some pictures. MTU Xbox Live - 5G Home Broadband

This is an ongoing investigation with many three users, and is growing by the day. There is currently nothing we can do as the MTU is automatically determined by three so even changing the settings in the router would not make a difference. There are other posts on here with people having the same issue, one of them being myself. Unfortunately there is nothing we can do at this present time.

I've seen several posts floating around the internet where people are having MTU issues when using 5G networks to connect to Xbox Live.

I currently own the 5G Home Broadband. I'm having the exact same MTU issue. When testing my connection my MTU is 1360. People are reporting they can change the MTU manually in the router settings but I couldn't seem to find the option to do so. 

I was just wondering has anyone fixed this ongoing issue? I've seen reports that date back to the beginning of this year with still on going solutions.

Hi @MrSimo98, @jamestaylor9999,

I'm sorry for the lack of updates on this particular issue. I'm trying to get this investigated further and have sent you both private messages to link you in with some colleagues that can gather account and connection info, and arrange for this to be looked into in more detail.

Thanks,
JonathanB

Hmm, interesting but I get a MTU value of 1500 (1472 + 28) with a Ping test from my PC.

Can someone with a MTU value of 1360 on their Xbox, try the ping test from a PC?
