wi: SIOCSIFMEDIA Error

I have been experiencing unreliable file transfers between my -stable machine and a W2K box using smbfs over a wireless LAN.  I am hoping that the reliability will improve if I set up the -stable machine to use hostap mode.  To this end, I upgraded -stable to the latest earlier today to get Warner's latest MFCed code.  Unfortunately when I try to

ifconfig wi0 ... mediaopt hostap 

I get

ifconfig: SIOCSIFMEDIA: Device not configured

Any thoughts on why this might be happing?

I am using pair of Hawking WP251 PCI cards.  I am including relevant messages below.

Cheers,
