I tested .337 and have encountered multiple stutterings and lags over time on xbox live via 2.4Ghz wifi. The connection seems so fast whenever the game starts but it will begin to lag and eventually the game becomes unbearable and the router needs to be reboot.Okay, here it is:

and here's the md5 checksum:

Note that there are no guarantees that there aren't other breakages in this firmware, it is beta. In fact, I wouldn't recommend playing with it unless you are experiencing the specific wireless IPv6 problem at issue.
How should I resolve this problem?
