Xbox 360 breaks our router's internet connection

    A few months ago a strange thing happened that has now become common.

    The set up

    The Xbox 360 is wired to a WRT54GS-UK v5.1. The 360's network settings are set to automatic because no matter what I try with a static IP I cannot get better than a moderate NAT (unless I power cycle the router and then the first two Live tests report an open NAT, but it goes to moderate from the third test onwards, whereas it's always open with auto settings). UPnP is enabled. The 360 is currently the only DHCP device in use, all other notebooks and the desktop are set to static IPs.

    The problem

    Every time I download something from the Marketplace or try to download a game update the router's internet connection breaks for all wired and wireless devices connected to it and the only way to fix it is with a power cycle. After a power cycle I can download these things successfully for a short time before it breaks again. Gaming never causes any problems.

    Further information

    I've tried firmware versions 1.50.9 and 1.51.0 and still get the problem. I recently got 1.50.5, 1.50.7 and 1.50.8 to try. I'm hoping 1.50.5 will resolve it, as that's what my router shipped with, but I'm sure this problem occurred before I upgraded from 1.50.5 so am not confident it will.

    I always revert to factory defaults before upgrading the firmware and I never restore a previously saved configuration file, I set it all up again manually.

    My router's still under warranty for another few months and because I can't find a file needed to revert the GS to VxWorks (do you have the ZIP file you can send me: vxrevert_manual_gs_v06.zip), I'm a little reluctant to try installing DD-WRT.

    Questions

    1) Does anybody know why this is happening?

    2) Do you know how to fix it failing the firmware versions above?

    3) Is DD-WRT micro the answer and more stable than Linksys' firmware?

    4) Should I try and exchange my router for another one?

    Thank you in advance! :)

    Never had confirmation of this, but I think XBoxes talk funny via UPnP, and that breaks routers. Try turning UPnP off, and see how goes.

    If you need to manually open ports on the router, it's not so bad if it's outgoing ports. Be very careful when opening incoming ports however.

    Also, I don't know if this is possible with stock firmware, but try limiting your "remembered" connections and the duration there-of. On Thibor's firmware it's termed "Max Connections", and "Established State Timeout". Some games tend to overload the IP conntrack (connection tracking), causing the router's memory (of which the V5.1 don't have much) to run out.

    I don't think exchanging your router would be any good (except if you can get it swapped for a GL). This funny router behaviour with Xbox seems quite common if you search this site.

    Thank you for the informative repsonse, that's the best explanation I've had yet. :thumbups:

    If I turn off UPnP I can't get better than a moderate NAT on Live.

    I've tried using port forwarding, but this requires a static IP and again I can't get better than a moderate NAT.

    Since finally getting firmware 1.50.5 and putting it back on I've been able to download things from the Marketplace without it breaking the internet connection. I haven't tried Live with versions 1.50.7 or 1.50.8, but 1.50.9 and 1.51.0 suffered the break. The strange thing about when it broke the connection was all the router's activity lights would still be flashing like normal.

    Hopefully it will remain stable.
