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.
