Ath0 802.11 comes up with Sam's patch but shows no carrier and I can't make it connect.

Fri Jun 20 13:20:31 UTC 2008

To close the thread:

The ath0: <Atheros 5424/2424> mem 0xf2200000-0xf220ffff irq 19 at  
device 0.0 on pci5 is WORKING and I'm using it to send this message.   
I still have a lot of polishing to do at boot time and I may have some  
conflicts with the nfe network card or having dhclient called for both  
from rc.conf.  For now I will do it manually on boot.

The credit goes to:

Sam for his patch http://people.freebsd.org/~sam/ath_hal-20080528.tgz

Sylwester for giving me another approach.
Andrew for reminding me that dhclient wasn't bringing the interface up.
Paul for the rtfm, etc. actually the read the NEW ath wlan manuals and  
UPDATING, that really got me started.

Now I have to find how to make the connection far easier than manual  
and rc.conf and the different authentication.  I guess now I would  
like a nice little window that shows the scan and lets me add the  
password in X rather than using ifconfig

Thanks again,

ed
