What to Do If Receiving MTU Error When Connecting to Xbox LIVE

 

If your Xbox 360 console is connected to the Internet but unable to connect to Xbox LIVE, and you received an MTU error after running the Xbox LIVE connection test, follow the steps below:

I. Restore the Network Settings of the Xbox 360 Console to Factory Defaults

NOTE: Before you reset your Xbox 360 console, take note of the current network settings and wireless password (if you are connected to a secured wireless network) so you can restore them later on.

STEP 1: Press the Guide button on your Xbox 360 controller.

STEP 2: Select Settings, then select System Settings.

STEP 3: Select Network Settings, then select Wired Network or the name of the wireless network (for wireless connection).

STEP 4: Select Configure Network.

STEP 5: Go to the Additional Settings tab, then select Restore to Factory Defaults, and then select Yes, Restore to Factory Defaults when prompted.

NOTE: This will only reset the network settings of the Xbox 360 console and will not reset the other settings.

STEP 6: Turn off the Xbox 360 console.

STEP 7: Restart the Xbox 360 console.

NOTE: If you will be connecting to a wireless network, you will be prompted to configure the wireless settings. Follow the on-screen instructions to connect to your wireless network.

III. Disconnect Third-Party Headsets and Other Possible Interference

Third-party wireless headsets and other wireless devices can cause active interference to your wireless connection since they are running on the same frequency as that of the wireless router. Below are some of the possible interference culprits:

  • Wireless headsets
  • Cordless phones
  • Microwave ovens
  • Chrome faceplates
  • Metal dividers
  • Shelves
  • Doors on the entertainment unit where the console is placed

Once all possible interference have been cleared, test your Xbox Live connection. If the same problem persists, proceed to the next instructions.

NOTE: When dealing with interference, it is best to consider positioning the Xbox 360 console in line of sight with the wireless router. You may also change the wireless channel on your router to further isolate the problem.

IV. Restart the Xbox 360 Console and the Network Hardware

STEP 1: Turn your Xbox 360 console and your network hardware (modem and router) off.

STEP 2: Wait for a minute or so, then turn your modem back on, and then wait for it to get back online (usually takes one minute).

STEP 3: Turn on your router and wait for another minute.

STEP 4: Restart your Xbox 360 console, and then test your Xbox Live connection. If the same problem persists, proceed to the next instructions.

V. Connect the Xbox 360 Console Directly to the Modem

Try connecting your Xbox 360 console directly to the modem instead of the router to further test the connection. To connect the Xbox 360 console to the modem, follow the steps below:

STEP 1: Unplug the network cable connecting your Xbox 360 console to the router. Make sure to leave the other end of the cable connected into your Xbox 360 console.

STEP 2: Unplug the network cable connecting your router to the modem. At this point, neither the modem nor the Xbox 360 console is connected to the router.

STEP 3: Connect the Xbox 360 console to the modem using the same network cable that is still connected to the Xbox 360 console.

STEP 4: Turn off your Xbox 360 console.

STEP 5: Unplug the power from the modem, then wait for one minute, and then plug the power back in.

STEP 6: Wait for the modem to get back online (usually takes one minute).

STEP 7: Restart your Xbox console.

STEP 8: Test your Xbox Live connection.

NOTE: If the same problem persists, contact your Internet Service Provider. Otherwise, the problem lies with the router. You may need to upgrade the router’s firmware or make changes with the firewall settings to allow the connection to go through.
