    Xbox 360 can't connect to internet: MTU error


    What happened: we went on holiday for a week, leaving all gadgets at home unplugged from the mains electricity. When we got back, the Xbox 360 could no longer log on to Xbox Live. All our other gadgets can connect to the internet as normal using a mix
    of wired and wireless connections.

    The router is a Zyxel VMG1312-B10D.

    The Xbox 360 error messages are as follows.

    When selecting an account to log on to Xbox Live, the Xbox 360 responds with:

    Your console can't connect to Xbox Live.

    8015190E

    I then tried testing the Xbox live connection using the Xbox 360.

    This reports that the Xbox 360 can connect to the home network, but "can't connect to internet".

    Suggestion 1 says MTU error and recommends unplugging the router/modem from the power for 5 minutes. Suggestion 2 says MTU error: visit www.xbox.com/mtu-help for more help.

    I tried both suggestions. www.xbox.com/mtu-help doesn't exist any more. I found several recommendations on-line that say Xbox Live requires an MTU set between 1364 minimum and 1492 maximum. I checked my router: it had MTU set to 1458.

    I looked for help on-line including using the troubleshooting guide here <https://support.xbox.com/en-US/xbox-360/networking/connection-error-solution> and followed recommendations to do these things:

    1) Turn on Universal PnP - I had already done this when we got the Xbox 360, and UPnP was still turned on when I checked.

    Specifically, the router settings for: UPnP and UPnP NAT-T are both enabled. It says that "UPnP NAT-T only works when NAT is enable" (yes, "enable" not "enabled").

    When I look at the UPnP setting on my router, it reports an Xbox at IP address
    [mod removed personal information] with a connection: external port and internal port 3074, protocol UDP.

    2) Try a wired home network connection: I plugged the Xbox 360 into the home Ethernet and told the Xbox 360 to use it.

    3) Reset the Xbox 360 network settings using Network settings: Restore To Factory Defaults.

    4) Clear the Xbox 360 cache.

    5) Set manual firewall rules to open up the ports listed here:

    <https://support.xbox.com/en-US/xbox-360/networking/network-ports-used-xbox-live>

    6) Set NAT to do port mapping like this using the appropriate IP address (192.168.1.233 in this case):

    : Start : End : Map
    Description : Protocol : port : port : port

    Xbox 360 TCP 53 53 53
    Xbox 360 UDP 53 53 53
    Xbox 360 UDP 88 88 88
    Xbox 360 TCP 3074 3074 3074
    Xbox 360 UDP 3074 3074 3074

    7) Put the Xbox 360's IP in the DMZ of my router.

    I tried all the above suggestions, and after making the last changes powered off the router/modem and Xbox 360 both. I left the router/modem for the recommended five minutes, then plugged in and powered up the Xbox 360 again. The Xbox 360 still can't
    connect to the Internet.

    I'd appreciate any suggestions on how to solve this problem.

    :)
