Re: hello my mtu is sayin its failed
The MTU(Maximum Transmission Unit) failure when testing the xbox's connection can be do to a few things because Xbox live requires a minimum MTU setting of 1364. Sharing a slower internet connection with other PC's in the house can cause this error, The incorrect MTU setting in your routers programming can cause this error, The lack of firmware updates to your router can cause this error, an older modem from your service provider can cause this. Old or worn network cables and jacks and or RG(coax) cables if you have cable internet could cause this. Your Router or gateway could be incompatible with Xbox live.
Try a direct connection to the Xbox without a router and reset your modem before doing it. If your able to connect then you know its the router. If not you know its the modem or cables or jacks or even your Xbox if you havent tested it elsewhere.
You can tell your ISP to mail you the newest updated modem... sometimes they will have a guy just drop one off.
I had the same MTU error issue with the SBG1000 and XBOX. The issue is your firewall settings. There are a number of ways to resolve. If you want to verify this, temporarily turn off the firewall on the router settings, should work.
SBG1000 Settings: 1. Forward ports, 53, 3074 and 88. (You must also open these ports in the custom firewall settings)
OR 2. Set the Xbox IP to be in a Gaming DMZ
Search the internet for firewall settings with Xbox for step by step. The following may be a good primer: http://portforward.com/english/routers/port_forwarding/Motorola/SBG1000/Xbox_Live_360.htm

1) Which connection did you talking about LAN/WAN?
2) Xbox live may not be up yet, can you verify it?
Most home gateway routers can only change WAM MTU for certain
connection type (PPPOE), and cannot set MTU for LAN and other WAN
To change MTU for PPPOE, going to WAN connection setting, and you will
see the MTU options box. But do not change it unless your ISP told you
to do so.
So make sure Xbox live is online -- I am no Xbox fun so I have no idea how it works, but just guess from your message.
In some cases, MTU is not necessary to adjust. Its always automatic and
defaulted to 1500. The router model that you have doesn't have MTU
settings. You can download the User's Manual HERE. You must do port forwarding and open the xbox live port so you can play xbox live. If it keeps on telling you about MTU, you must set static IP address on your xbox's settings and power cycle your devices.
It's not the MTU problem any more. Its the router's firewall. To resolve it, you two steps to try. First, try to do port forwarding, you must forward the port for XBOX Live to the router's admin page. I believe the ports are 3074 TCP and UDP, 53 TCP and UDP, 88 TCP and UDP. If that doesn't work, try to just disable the router's firewall itself. One of these steps will surely fix your problem
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.
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!
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...
