You mean, with out a wireless router ? Presumably both computers have wireless adapters -- if so, you need to establish an ad hoc connection. See manual which came with the wireless adapter or Google "ad hoc network".
Next time you post try to explain a little better, it's not helpful having to presume or guess when trying to answer.
