Hi I've had trouble lately with trying to system link myself to get an infectable mod menu so I can host some lobbies on MW2.I do exactly what the tutorial says to do and I can never seem to get it to work could someone please help me.

--------------------------------------------------------------------------------------------
I'm using two wireless adapters to get online"which I know is possible to do it that way."
My Jtag is banned will that affect anything?
I am on the latest Title Update.
I've tried multiple patches so I don't think it is the patch.
Both my retail Xbox and my Jtag is connected to the same internet connection/router
------------------------------------------------------------------------------------------
If someone could please help me it would help out a lot .
