Access the routers setup page by typing 192.168.1.1 (ip address of the router) on the address bar on IE.

then on basic setup page at the bottom part of the page you will see MTU normally its on auto,
to change the value set it to manual. ask your isp what is their prefferred value for the mtu you can go as high as 1300 to 1500.

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.

Connection problems


MTU stands for "Maximum Transmission Connection". Some routers and/or network gateways are incompatible with Xbox LIVE, while others may be compatible but merely need to have a setting changed. If you compare your router to the list of routers at the following web address, you can confirm whether or not your hardware has been confirmed as compatible with Xbox LIVE by Microsoft:

http://www.xbox.com/en-US/support/connecttolive/xbox360/homenetworking/equipment.htm

Whether or not your hardware is listed as compatible, it would still be a good idea to check your instruction manual for the hardware you are using and see how (if possible) to change the MTU settings. Microsoft suggests that the MTU setting should be 1364. Using untested hardware or hardware not listed as compatible may still work, however, future updates to LIVE may suddenly make your hardware incompatible, as updates to LIVE and the Xbox console are made to work with the specifications of tested and listed compatible routers and gateways.

360 mtu test keeps failing


Using the main computer, open your Internet Explorer and on the Address Bar type http://192.168.1.1

It will prompt your for username and password. By default leave it blank on username and type admin on the password

Under SETUP tab, you can see there MTU, set it to Manual and set the size to 1400 then click on SAVE SETTINGS at the bottom.

Now powercycle your devices. Turn off router first and then modem. Wait for 30sec. Turn on modem first, wait for lights to stop blinking then turn onrouter.

That's it..

Mtu test is failing


I've had the same problem and struggled with it for hours... If your on the Comcast network, there seems to be problems with adjusting MTU. I have a Dell 2350 router and that particular router cannot have MTU modified. Also, sometimes the MTU is effected by computers or phones in the house being on. One more suggestion, try a gaming router. Good ones start at 90 dollars, somewhat expencive but well worth it.

Mtu failed


what kind of router are you using to connect your xbox 360 to? usually you can define the MTU size in the router configuration.. default for xbox 360 live is 1364 ... check out your web configuration on your router to see if you can change this!

XBox 360 MTU Failed with Router


MTU of 1500 is the standard TCP/IP message length. Only MS Vista allows that to be changed dynamically. If your ISP uses 1500 then you need to use it too. Your Xbox protocol may be blocked by your ISP. You may want to give them a ring...
