ath0 driver

Ive got a Dlink DWL-G520 that Ive installed into a Freebsd system. Ive set up 
the card with the following
ifconfig_ath0="inet 10.0.0.1 netmask 255.255.255.0 ssid daves channel 10 media 
DS11 mediaopt hostap"

This system was cvsuped and buildworld about 3 days ago. The card appears to 
be working because when I try to connect with my PDA it shows full Link and 
quality, and when I ifconfig ath0 down , the link and quality go down to 
nothing. 

However it doesnt give out dhcp addresses over this interface. Im sure my 
dhcpd.conf is fine because I've used a similar one on a laptop => aka 
wireless access point that worked very well. So I tried to use dstumbler to 
see if it could detect the PDA, however it gives me the following error

 error: unable to ioctl device socket: Operation now in progress

and it stays that way. 

Has anyone had this issue as well or now what it means?

Thanks

David
