>Description:
Nothing is ever received by ath0 on an Acer Aspire One A0751h-1279 under 8.2, 9.0-RELEASE, 9.0-STABLE or 10.0-CURRENT. It works on Ubuntu-10.10 (only version I tried). I also tried an AR5B95 card, and had the same results (works on Ubuntu, not on FreeBSD).
I had the PCI mapping problem under 8.2 (see
http://lists.freebsd.org/pipermail/freebsd-mobile/2011-June/012364.html for more info). I discussed this matter on freebsd-wireless starting with
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=87215+0+archive/2012/freebsd-wireless/20120212.freebsd-wireless
Here is what shows up in dmesg.today for ath0 with 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 at 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
>How-To-Repeat:
Try to connect to a WiFi network with an Acer Aspire One A0751h-1279 netbook running FreeBSD 8.2 or later.
