Alright guys....i am pretty computer illeterate, so i was wondering if you could explain how to bridge the LAN connection to the other connection. I run vista. If someone could help me it would be appreciated.

I think you highlight the two connections so they are blue, then right click on them and it should say bridge connections. Then click on that.

Exactly.

Another question for anyone who could help me. I've got my xbox 360 connected to my PC through my network port, connect through a wireless connection and I have bridged the connections in order to play on xbox live through the PC. It works very well, very solid connection. The only problem is, I get booted from the game pretty consistently when I'm playing, but it doesn't totally disconnect me xbox live, just from the game. If anyone here has played halo on xbox live, it sends me into a blue screen and says acquiring new host (or something like that) the exact same way it would do if the host of the match quit the game, except when I get out of the blue screen I'm the only one left in the game... meaning i was disconected from the host. Any settings I can change or anything I can tweak to make it hold the connection better?

This website has instructions on how to connect your xbox 360 wirelessly via a latop or modified router to xbox live. More importantly these are cheap options compared to the standard xbox 360 wireless adaptor

How to connect to xbox live wirelessly

Hello This will hopefully help those of you who cannot/don't want to but the official xbox 360 wireless adaptor.

There are several different methods of connecting your 360 to xbox live wirelessly:

1) Official xbox wireless adapter
2) ICS/Network bridge connection with a wireless laptop/pc
3) Modified router
4) Gaming router

ICS did not work for me, and many people have reported the same particularly in vista. Network bridge connection seems to function for most people. It involves bridging your pc/laptop's wireless connection with its LAN connection. You then connect an ethernet cable from your laptop/pc's LAN port to your xbox 360's LAN port.

Modified router as an option is technically more difficult to achieve. This involves turning a router into a wireless receiver so it communicate with your router that is connected to the internet. This is possible by using 3rd party software to flash the existing router firmware : DD-WRT. Not all routers are compatible.

Gaming routers are almost as expensive as the official adapter and can be hard to setup. There are wireless N gaming routers that offer much better performance than the original adapter.

When using wireless option to connect to live you may notice your NAT is moderate (or worse! ) This can be remedied by either turning on UPnP on your router, DMZ or portforwarding.

This site has some pretty solid information on the topic as well as step by step guides:
