Hi all,

  I compiled a fresh kernel from -HEAD and rebooted in the hope that my
laptop's wifi would now be supported (I saw the commit messages in January
about it possibly supporting Centrino Wireless-N 135). However, while
it does attempt to bring the wifi up, the link just goes up and down
and does not work properly.

  Knowing that the BSDs are fairly close and share some code, I did try 
the OpenBSD driver and it works. Is there some code that could be missing
from the FreeBSD iwn(4) to stabilize it? I'd be happy to test any patches.

Kind regards,
Tom
