I am looking at "extending" a wireless signal to a remote location. There are actually 3 buildings involved in a row in a span of 400 yards. Building #1 currently has wifi and when standing outside of building 2 I can pick up a pretty decent signal. What I want to do it have wireless in building 2 and building 3 and was looking at 3 of the repeater/access points listed below. I have messed with WDS in a very limited capacity using some tomato flashed linksys boxes with good results.
