WiFi Connection ICS Question

[iTek]

I currently access the internet via a WiFi Connection provided from BT.

I was wondering if its possible for my laptop to also connect to the internet using the connection perhaps using ICS through my main computer?

I tried to create a ad-hoc using the windows program but it didn't seem to aid, infact it always disconnects me from the internet connection.

I don't know much about networks unfortunately.

Any Help Appreciated.

Its a BT Open Zone area, basically I am in the armed forces paying for this wifi connection but I can only connect one of my items to the service, I was looking for a way to connect both.
