i know its possible to use an apple airport to share wifi, but i dont have that luxury where i am at. the way i connect through the internet is through a USB modem stick. my question is: is it possible to share the internet through my MBP without using an airport or router of any kind? i saw some videos on youtube on a PC sharing internet and i would love to try to connect my XBOX to it. not to play online, its waaaay too slow for that... but to connect to my profile and update if i need to. any ideas or way i can do this with my usb modem? also if anyone has suggestions on how to get better internet through those things im open for that too. just wasnt really sure where to post this.
