I can only tell you of my own experience. I have installed three wireless networks. Two in school, and other in an office. All of theem was secured. I used the WEP for all of them then I limited the distant and the channels of each access point. Finally I wrote down the MAC and IP of each access point just in case they when down. Then finally I took a secuirty tour with a handheldto make sure the lock out worked. This system has been up an secure for two years. It takes work but wireless can be secured.
