I want to blog around because I want to remember also by my self. 
It could help to somebody else who decide using opensolaris natively.
Lot of thinkgs you need is writen here and I did simply this steps.
# svcadm restart nwam
One time I wrote incorrect security keys
#dladm show-secobj
#dladm show-wifi -p
#dladm delete-secobj nwam-<essid>-<bssid>
#svcadm restart nwam
Thanks for sharing your experience with us (and it's good to know there there is another Sun employee using OpenSolaris--the most promising OS in the history of mankind :-) )
BTW, you forgot to mention that you don't have to switch to root to issue the svcadm command. In OpenSolaris, you can do it as the login user:
pfexec svcadm restart nwam
Viva OpenSolaris!

:) It's funny you marked opensolaris like most promising OS in the history of mankind :) True is opensolaris has very big potential. It only depends how will be driven. Future show it to us.
Thanks for comments
