Win7 ICS problem

[KinkiKowBoi]

Hi all, sorry if this is a noob question. If so, flame me all you want haha. I'm pretty new to networking also so if you guys got any awesome tips, thanks But yea, to get to the point, I own a 802.11n wireless card in my desktop which is connected via ethernet. What I'm trying to do is to create an ad-hoc network so that my dorm room can get wifi from anywhere within a reasonable distance. The problem is, everytime I try to create an ad-hoc, (after the network name and security key window), it says my network is create but sometimes, it doesn't ask the option "Turn on internet sharing". When this doesn't appear and I try to join the newly created network, my laptop won't connect but when the option appears and I proceed with it, then my laptop will connect. Is there like an option to make this appear or am I completely being retarded and need to research? Thanks! Any and all opinions are accepted, even noob bashing at this point

It might be that the school's Network does not allow further use beyond one computer.

Thanks for the reply! I've done it before, as in set a network so my friends could connect to it but it's like random. Sometimes, when I start my computer, the button pops up, other times, it doesn't. I never know when I can make a network or not :/
