Sure, that shows that your environment is quite noisy. :-)

But is transmission just plain not happening? Is it just never
associating? Or is it sometimes associating and sometimes not?



It's a bit crowded here ; )

Well as far as I have observed, it never associated.

ehm, well.. ath0 seems to be, wlan0 however not:

Adrian,

Finally, I managed to get again a 9.1-RELEASE running with a recompiled
kernel.

This is the result of athstats:

Is it somewhat helpful?

Still with 9.0-RELEASE:

.. I can't tell here whether there's any interrupts making it to the
ath0 device or not.

The driver in -HEAD logs the TX and RX interrupt counts in a ath
sysctl which I can track.

Can you please compile up athstats and recompile your kernel with:

ATH_DEBUG
AH_DEBUG
ATH_DIAGAPI

.. as we will need to establish whether you're actually queuing frames
to the hardware, whether they're going out, whether the hardware is
actually completing them, and whether the interrupt is being
generated.

Thanks,



Adrian

Hi,

Would you please look at the output of vmstat -i, see if the ath0
device is receiving interrupts?

Thanks,



Adrian

Hi,

after a downgrade to 9.0-RELEASE the issue remains the same.
/var/log/messages is spamed by equal authentication timeout entries.

Would you please try 9.0-RELEASE too?

Hello,

I'm facing a problem with ath0 on FreeBSD 9.1-RELEASE, that was
not
existent
on 8.x-RELEASE.

The issue seems to be the similar to this one:



http://lists.freebsd.org/pipermail/freebsd-stable/2012-January/065667.html


I do have the same NIC. pciconf -lv output is equal:

ath0@pci0:2:0:0:    class=0x028000 card=0x3a701186 chip=0x0024168c
rev=0x01
hdr=0x00
        vendor     = 'Atheros Communications Inc.'
        device     = 'AR5008 Wireless Network Adapter'
        class      = network

/etc/rc.conf:
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"

/etc/wpa_supplicant.conf:
network={
ssid="home"
psk="123"
}

However, it is not starting to work.

I do not have /usr/src/tools/ath so that I can not provide the
output.

/var/log/messages is spammed with:

Feb 10 09:08:26 gomorrha wpa_supplicant[1500]: Trying to associate
with
xx:xx:xx:xx:xx:xx (SSID='home' freq=2422 MHz)
Feb 10 09:08:30 gomorrha kernel: ath0: device timeout
Feb 10 09:08:36 gomorrha wpa_supplicant[1500]: Authentication with
xx:xx:xx:xx:xx:xx timed out.

Any idea what might be wrong or how I could fix this?

Kamil
