I have four computers, two of which are hard-wired and have printers running on them. The other two are wireless (w/ wireless router). I wish to create a home network and hook them all together so that they can share printers and software - is this possible? I have tried sharing printer and wireless computers are not recognizing it. Also, want to share software off of one of the hard-wired computers and place a WEP seucrity on router.
