oh, youll need a lan nic, and a wireless nic(or adapter w/e) and regular old cat5e cable to do this.i dont know why some people say you need a crossover.
first, on ur pc/laptop go to internet connections, right click on your wireless connection.
under the advanced tab on the top enable internet sharing and allow users to change settings.
connect your 360 to your nic on ur pc/laptop and power up the 360. it might or might not immediately enable the connection, if not manually do so.
now find your lan connection under internet connections. double click it. you should of received 192.168.0.1 for an ip address. 255.255.255.0 for subnet address. default gateway should be blank. if the above info isnt the same then manually change it by going to properties>tcp/ip> manually enter ip address. do not input dns. leave it blank.
now on your 360 console dashboard, goto system>network settings>edit settings.
youll see basic settings. underneath that you will see your ip settings. you might already have an ip, if so press b to go back a page and scroll to test xboxlive connection. select. it might hang for a little while on mtu, and icmp, just let it do its thing. if your connection is good you should be able to successfully connect to xbox live, your ready to go. if not, you might have firewall/router issues. if you dont think its the router or firewall follow the next set of instructions.
the first set of instructions worked when i set up my friends 360, but didnt for me. you can try this.
go back to the dashboards network settings, edit, ip address. enter a manual ip of 192.168.0.240, a subnet of 255.255.255.0 and gateway of 192.168.0.1.
goto dns servers below, change to manual and enter 192.168.0.1 it should say that anyway but type it in just the same and then in the secondary field type 000.000.000.000. if it gives you an error, change back to automatic. this works, even tho it sounds silly.
you should automatically be good to go. if not disable both wireless and lan on ur pc from network connections and then in this order re-enable; wireless, lan.
hope this works for everyone else, as it has worked on 4 360's for me.
if you have any troubles with this email me at
