I tired of this stubborn problem and to save us both time, I installed an intel wifi card and all works fine now. Too bad those broadcom cards are such a headache. Many thanks to all the time and effort put into helping me! I really appreciate it! I have also learned a lot from the helpful direction. Thanks again! –  user277445 May 15 '14 at 20:27
