Halo 3 matchmaking and lagging!?

when i start matchmaking, its says something about my NAT and that matchmaking will be slow.





AND





i've been having numerous games that have been "lagging" or not working. i will be walking, then reappear somewhere completely different. Or i'll be walking and then just fall down...somebody tell me how to fix this.





i've got a wireless connector on the back of my xbox that costs a $100. the guy at circuit city told me that once i bought that, that i shouldn't have any problems with my connection, yet im having a miserable playing time!





SOMEBODY PLEASE HELP ME!!





thanks!

Reply:try to reset your xbox 360 and see if that works im sorry
Reply:try testing the connection at xbox dashboard or something like that
Reply:Your NAT is based on your router, not the adapter on the back. Get into the settings of your router and you should be able to adjust the NAT.
