first check your basic connectivity. if you see you have a good wireless connection on each, see if you can ping each other (start/run/cmd then ping )
if you can ping, probably all you are missing is the same user login and password on each box and then you need to share something or there won't be anything to 'see' except the computer in network neighborhood. to create a share, right-click on a folder and pick Sharing. if you do not see this as an option, you need to install File and Printer sharing (right-click the wireless connection in Network connections, then Add the File and Print sharing service)
