wireless setup in sysinst? and no notice about dhcp failure

What is the recommended / supported way to use wireless card when 
installing NetBSD (to get sets over network for example)?

I escaped to shell and used ifconfig to attempt to setup nwid and nwkey. 
(That didn't work due to missing firmware -- see other email.)

Also the dhcp client failed in sysinst.

But the screen blanked and had prompt for DNS domain, then hostname, then 
DNS server.

No real indication that DHCP failed other than IPv4 address was not set. 
If someone didn't notice that, they may think it worked.

Probably should have prompt or message about DHCP client failure.
