The only other thing I can think of, is your use of a 104bit key instead of a 40bit key. Try using a 5 digit nwkey and see if that works. The man page states that the longer keys only work on some newer cards.
I'm not sure if the 'nwkey testpassword9' in the hostname.if file is correct or not, someone else may be able to confirm that. The hostname.if(5) manpage states that you can do commands by using a pipe char. Something like this might work in your situation: media DS11 mode 11b inet 10.0.1.5 255.255.255.0 10.0.1.255 |wicontrol -k testpassword9 Hope this helps.
