    So if I follow the thread, WEP is OK ... j/k.

    Upon further digging with my staff, we have very few wireless devices even
    on that network. Therefore scrapping them won't hurt as much as I thought.
    Mr. Martin's last post does raise a question; how fast can you rotate keys?
    Why not every 3 minutes? I assume overhead would be a problem.

    Lastly, my preferred solution is Trapeze Networks. There system seems very
    slick with the multiple security systems I need. The next closest was
    Extreme Networks, but they don't seem to be as advanced. Plus we have all
    their switches and the APs are same fruity purple. The questions is, has
    anybody had any experience with Trapeze (good or bad), they seem to be newer
    company. Any intel would be awesome.
