Well you might be able to connect the Xbox to the laptop using the Ethernet cable, then using the laptops wireless card to connect to your wireless network - then turn on internet connection sharing to share the connection via the Ethernet cable to the xbox.
I have done it in the past with a laptop running win xp pro to a desktop running win 2000. idk if it works to the xbox or not but you could give it a try.
And sry I don't remember where you turn on internet connection sharing, trying googling it if your stuck.
Hope that helps :D.
and idk if AOl throws a wrench in the works or not. I dont voluntarily install virus's so have never used AOL :D.
