I tried 4 seperate cards with the opensource wireless driver before using the IOXperts beta driver. Let me just say that after spending hours (maybe days) of wasted time trying to get the opensource driver to work in any way possible, it was quite refreshing to download this beta, install it and have it work excatly as it should (including WEP which refused to function under the previous driver). Needless to say, I instantly registered. Thanks.
