I was having an awful lot of trouble with the wpi0 driver and my ThinkPad. Wireless connections were terribly unstable, if I could connect at all. It may have been obvious to some but it took me a while to figure out that opensolaris didn't like WPA2 encryption, and reverting to 128 bit WEP only worked if I used a 13 character password. I had a 10 character password and the connection was flaky; after resetting the AirPort base station to a 13 character password for the network, the connection has been up for a few hours and is fast and stable.
It seems so simple now. Maybe I was a little dense and it took me a while. Hopefully this may help others were are similarly situated from a lot of frustration. This message posted from opensolaris.org
