NETWORK SETTING AND STATISTICS

Been experiencing a LOT OF LAG recently playing Destiny on line... I have checked network stats and MTU is shown as 1480 ... on xbox one BUT Asus DSL-68U router has MTU set at 1492 (which is optimal setting) WHY is this? and can I change the MTU on the xbox? Latency
runs at 205 ms which is also not good... My Download speed is 9.31 Mbps and Upload speed 0.56 Mbps. I live in Australia (that's why internet speed is so ****). (hard wired to modem not wireless).

Anyhow according to a tech site my modem's optimal MTU setting should be 1492 which is what it is set at and the xbox one support shows that the MTU on the xbox is set by the modem BUT it is 1480 so there is an issue somewhere? Apparently settings below
1492 will cause packet loss ... How do I find my optimum MTU setting? AT&T Southeast Forum FAQ | DSLReports, ISP Information

Thanks Laurie

Streaming apps and Notification pop-up are still broken. What is Going On?

The only hard drive I have used is the one on the Xbox One. Also here the internet network statistics:

Download Speed: 16.36Mbps

Upload Speed: 1.04Mbps

Packet Loss: 0%

MTU: 1480

Latency: 105 ms

I don't think you understand what an MTU is. 1500 is the maximum setting, but anything over 1358 works fine for XBL. the extra 20 wont' make any difference. If you have slow downloads its probably a problem with your internet/router. Check your router settings
the MTU might be even lower then 1480. I'm not sure where you got your info from but whoever told you that is wrong.

You may want to look at your DNS speed. I'm running on the Google Public and it speeds things up for me.

8.8.8.8

8.8.4.4

Thats the problem when I play Fifa 14 with a friend over the internet everything run fines. If I play a random person on the internet the games feels sluggish and unresponsive

1500 isnt better than 1480.

1480 is just fine.

Any lag will be caused by other things

To start with the BT homehubs are not fit for purpose

The wireless on them is prone to jitter which is a cause of lag

If you are using wireless then try wired.

Also the hubs have dodgy UPnP which either isn't fully compatible with Xbox one or just randomly stops working depending on the hub version. This causes NAT issues.

After having no end of problems with live due to the homehub 5s not being fully compatible with xbox one(and ps4 which proves the hub is to blame) I binned it and bought a tplink router.

Now after setting up static ips using address reservation I almost always have an open NAT and lag is rare. I also get full connection speed for my line of 75meg which the home hub couldnt even manage wired. All this is with an MTU of 1480.
