I have an Acer Aspire One A0751h-1279.  It came with an AR5BHB63, and I
have also tried an AR5B95.  Wifi works on this netbook under Ubuntu
10.10 (i.e. I can get a list of nearby networks and connect to one and
transfer data), so I think the hardware is OK.  Under FreeBSD-8.2 I had
this problem:
http://lists.freebsd.org/pipermail/freebsd-mobile/2011-June/012364.html
but even after solving that issue (as described) no networks were ever
found while scanning.  I have since tried 9.0-RELEASE, 9.0-STABLE, and
even 10.0-CURRENT as of 5-Feb-2012.

There is a switch that is supposed to enable/disable the Wifi card, but
I don't seem to have to do anything with it under Ubuntu.  I have tried
turning the Wifi card on at various points in the boot and configuration
process with no change.

Here is what shows up in dmesg.today for ath0 witn the AR5BHB63
installed:

ath0: <Atheros 5424/2424> mem 0xd0000000-0xd000ffff irq 17 at device 0.0
on pci3
ath0: AR2425 mac 14.2 RF5424 phy 7.0

and this is what shows up from pciconf -lv:

ath0@pci0:3:0:0:	class=0x020000 card=0xe00d105b chip=0x001c168c rev=0x01
hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR242x / AR542x Wireless Network Adapter
(PCI-Express)'
    class      = network
    subclass   = ethernet

I boot the system and run the following commands and never get any
responses:

ifconfig wlan0 create wlandev ath0
ifconfig wlan0 up scan
ifconfig wlan0 list scan

Here is a sample of the output of ifconfig:

Is there any hope of this working?  Is there anything I can do to assist
in debugging this?
