Connecting to a Ad-hoc wifi network

How can I connect my samsung galaxy Y running andriod 2.3.6 to my laptop's ad-hoc network ?

Root it, and then there is a patch available that lets you connect to ad hoc networks. Search XDA forums for the patch. Look for something like "wpa supplicant"

Download Samsung Kies, PC Sync or NPS (New PC Suit) for Android. I know the Kies is the best. When you install the Kies you can find all the settings for wi-fi on the from window of Kies.

I Try it, If not sucessed then I will tell you another solution.
