XBL crashes during MW3 Online

While playing a TDM in MW3 my connection crashes (and freezes for 10 sec) after 2-3 minutes an after 10-15 minutes I'm always being disconnected from xbox-live...
I don't know what to do.. UPNP is activated an my Xbox is an "open host"! After a XBL connection test I receive the error code: W: 0000-000B X: 0000-F001 Y: 20A8-4840 Z: 0000-0000 ID: FFFF-FFFF which has the signification that I must have a problem with my Ethernet or with DMCT but I actually don't have any idea what I could change... Please help me!!
