Not enough mtu to go to xbox live at hotel

An MTU is the largest physical packet size, measure in Bytes that a network is capable of transmitting.. If messages are larger than the MTU they are divided into smaller packets before they can be sent. All networks have different MTU's which the owner of the network set at what they want to set it at. 576 is a very common MTU if you connect through PPP. 1500 is the most common MTU for Ethernet connections. The Xbox Live system requires your network to have a certain Maximum Transmission Unit (MTU). MTU values are important to the performance of online games. If this test fails, you can adjust the MTU setting on your network router or equivalent device to resolve the problem. Xbox live requires the network you use to have a maximum MTU. This is key to online gamesing. If the MTU fails then you have to adjust the router you are using. If you cannot access the router to adjust the MTU the you will not be able to play online games.

Xbox live cant connect mtu failed

This appears to be a common problem, most likely due to the recent Xbox Live server maintenance. Nothing we can do except for wait until Microsoft fixes things on their end.

If you have your Xbox connected through a router, most routers, on their control panel ( for example) give you the option of setting an MTU, or leaving it to default. This option is normally found on the setup page of your routers control panel.

MTU stands for maximum transmission unit, basically a speed thing.

If you can set it, change it to something above 1500 depending on how fast your internet connection is, but I am fairly certain that 1500 is the minimum that you would want to have set for xbox live.

Another way to do it is, if your router has this option, set the MTU to Automatic. That way your router (should) be able to do all of that dynamically as the need arises.

I hope this helps to solve your problem, good luck!

Mtu keeps saying failed

I assume you mean you can't play games online?

Is your account Gold or Silver? (Go the the Marketplace blade, then down to account information, membership.)

You can only game online with a Gold subscription, which is like $50/year.

Xbox live

You appear to be on a router where you flipped on a security switch in the router and now this MTU is not working properly. There is a small, small button on the back of your modem or router. You have to press it with the tip of a pen, it's that small! This will reset all settings on the modem or router and then you can power off and on the box for 30 seconds, leave it on and try again. ONLY DO THIS IF YOU OWN CONTROL OVER THE BOXES OR GET PARENTS PERMISSION FOR THIS KIDS! By default, all the security settings are disabled and go back to original working state for configuration or use or the box. If you turn on anything security related on your router or modem, this will give you MTU issues all the time! Stop touching those settings if you don't know how to configure a router.
