    I finally reached somebody at microsoft who could resolve this stupid problem. I plugged in my ethernet directly into the westell 6100 and kept failing the mtu test. The guy on the phone had me power cycle first which I did (disconnect from the wall the modem and the xbox for 30 sec. then, plug the modem back in first and wait for all lights to be back on. then, plug the xbox back in and run test. If mtu fails again as it did with mine, on the dashboard click restore to factory defaults then try and run test again. This did the trick for us! Now we are online. I then repeated the power cycling again because I wanted to try going through the airport extreme router to the modem to the xbox. It worked perfectly. just unplug everything again and repeat the process this time starting with the airport then modem then xbox. finally all is working!!!

We had the same issue. Here is how we fixed it. I had the xbox 360 plugged directly into the westell 6100 modem via ethernet cable. the mtu test failed everytime. I was extremely frustrated and called microsoft and verizon (dsl) about 10 times each and they kept giving me the wrong solution. (get a new modem, get a new server, pay us money and we'll figure it out etc...) Here is what a man at microsoft told me to do and finally it worked. Power cycle your equipment (unplug modem and xbox 360 for 30 sec.) then, plug in modem first and wait until all lights are back on. Then plug in xbox and run test. In my case mtu failed again. I was then instructed to go to my dashboard and restore xbox to factory default which I did and rerun the test. This time everything FINALLY passed. We were in business. I then decided to try connecting through my airport extreme router. I power cycled again starting with the airport then the modem then the xbox and ran the test and unbelievable as it sounds it all passed and my son is now sitting happily on the couch playing a game online with his xbox 360. This took away days of my life to get this simple thing done. I was given codes to change and change back on the computer, phone calls to everyone and the solution was so simple when you finally reach a knowledgeable person. Hope this will help save someone else the time I spent!

Bellsout6h and att are full of ****. they list a USB driver for the westell 6100 modem. its blatant false advertising. there IS NO DRIVER! when i download and open the zip its some "security catalog" and some some notepad installation nonsese that accompanies it.
they are a bunch of liars and morons. spread the word and maybe they will get a the message.

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.
