Well you can put a RJ45 cable between them (thru lan connection of course) and make sure the cable is set as crossed. Then you can set both laptops under the same workgroup...laptops should able to see each other.
Wifi is convenient but more complicated to set up. Sorry but last time I set up a wireless between 2 pcs was more than a year ago, able to do it thru search on Google.
Its easy to setup wireless between the two laptops, just have to use it in ad-hoc mode. You can do this by going into the wireless settings and making your own network.
