I had similar problems. *Very* slow and unstable connection using wpi0. 
And WPA never worked. I tried it with NetBSD 4.0 (just out of curiosity) 
and it was working very stable and fast (even WPA)!

I was running FreeBSD-7.0 RC3 and now -CURRENT. In both cases no 
success, so that I don't use wpi0 at all right now.
