Lots of ways; but it depends on what exactly you're trying to determine - for example, are you trying to see if the station is currently logged into any network, or a particular network, or if a particular network resource has been (or can be) attached, or if the station -can- log into a network (IOW if the necessary client software is present to operate on a network, even if not logged in presently), or something else?
