Last questions...If i get the cisco 501 what will I need to do to get it up and running if I have an AP for it already? Also, I'm having a hard time convincing my boss to look at wireless connection between the buildings because we had so many problems with our crappy linksys connection. I found the 13.5 dBi antenna you pointed me towards and also a 21 dBi that I guess is the top end. Once I put up the antennas what is necessary to connect them besides the AP if anything. I just trying to figure out pros and cons of my options.
