What to use?

I have 3 Pcs in a peer to peer network and connected to the internet via a Linksys BEFSR41 router. Now, I want to add a wireless link to 3 more pcs on the other building. My thinking is to connect a Dlink DWL-2100AP to one of the BEFSR41 Cat5 ports and another DWL-2100AP as client on the other building and connect this clinet to a switch and then connect to 3 more pcs. Is this setup workable? If not, what is the solution? Thank you. GL
