"connect to", then click "show all connections". right click "wireless network connection", click properties, and go to the advanced tab. check the "allow other network users to connect through this computer's internet connection" option and uncheck the "allow other users to control or disable the shared internet connection" option. click "OK" to apply your changes, exit out of the "network connections" window, and (on your xbox of course), connect to xbox live. this lets your xbox 360 piggyback on your laptop's wireless
connection and provides a good, strong signal every time (at least for me it does). i still would appreciated it though if you could figure out how to fix my adapter but this is a good temporary solution. i dont close my laptop when i do this so i dont know if it works when the laptop is closed. good luck connecting to xbox live and i hope this solution works for you.
