I have a EnGenius NL-2511CD PLUS card in my laptop which has been
working fine for a long time with NetBSD 1.6.2.  I upgraded to 2.0 RC4. 
The install system recognized and configured the wi card, fired up
dhclient and I downloaded the sets with it.

When I boot from the 2.0 RC4 install, the card is found by the kernel,
the light comes on, but dhclient does not get any offers, wiconfig wi0
-D finds no access point, manual configuration with ifconfig doesn't
work.

I assume a default option has changed and I need to tweak with "ifconfig
wi0 mediaopt <something>."

Can anyone please throw some light into the dark room I am in? 
Thanks!!!

Ian
