The 32-bit one is fine. I did some work on it and found many of the problems; however, the driver still did not work. When I contacted Realtek about the issue, I was told that they were working on a mac80211-based driver that should be available soon. On that news, I stopped work on the old driver. That was a few months ago, but so far I have not seen any new code. When they are ready to release it, at least to me, I have an Edimax 7811Un ready for testing. Larry
