I have been advised to seek help here as the phase lock loop is not
working.
In case it's relevant:
- the wifi was working if possibly slightly unstable until I upgraded
to 3.8.7
(to cure suspend and resume on a gma500 in an AAO)
- Downgrading didn't work

Thank you for replying
Unfortunately while I understood every word I don't understand what to do
For example by "once-only" do you mean that once written that's it forever or
do you mean once during install
For example I'm fairly sure everything was reasonably fine with 3.7.10 but when
I ugraded to 3.8.7 for better gma500 graphics chip compatibility things went
wrong for wifi but a revert has achieved nothing
Should I remove the battery from the netbook then do an fresh install of
openSUSE 12.3 with 3.7.10?
or something else?
Sorry to take up your time

You can use the latest compat-drivers release:
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5.tar.bz2
See: https://backports.wiki.kernel.org/index.php/Documentation/compat-drivers
But, before compiling, uncomment and set "export CONFIG_ATH_DEBUG=y" in config.mk

Wasn't there a recent change to ath9k which reverted an initval
change? Specifically for the AR9485?
The problem was an unstable PLL that shows up when you do aggressive
PCIe PHY power save.
The change was to go back to the previous PCIe initval array.

As a first step, can you disable Power Save and see if the issue persists ?
("iw dev wlan# set power_save off" and verify that "iw wlan0 get power_save" shows "off").
Sujith
.. and make sure you do a full hardware reset (power off, wait, power
on) when you downgrade or upgrade.
Some of the register settings may be once-only and require a power
cycle to change.

Ok.
Can you load the driver with more debugging options and post the kernel log ?
Please use the mask debug=0x8f49.
See http://wireless.kernel.org/en/users/Drivers/ath9k/debug

Sorry for delay, I had to find debugfs (easy when you realise there's a kernel
with it preinstalled)
I can't find the kernel log file - it's not (obviously) in /var/log (and Google
is not proving to be my friend)
after
modprobe ath9k debug=0x8f49
dmesg only contains entries relating to power_supply BAT1

Some register values can only be written to once. Writing to them
again without a power cycle doesn't change anything. You need a power
cycle.
If any of these registers were adjusted when you were testing
different kernels, you may end up having that old setting affect the
new (or old) kernel.
You'd have to physically power off the laptop between reboots.

should I
- turn power save off
- reinstall 3.7.10 (start again with openSUSE 12.3)?
Grateful people are helping, sorry if I'm being stupid

I had connected a wifi network extender which borked (at the same time
that I upgraded the kernel for better gma500 support)
I removed the wifi extender but subsequently had all the problems.
However the source was a tick box in my Netgear router that I don't
remember setting (or it gets set by using an extender, I've not explored
that)
This provided wirelss isolation limited to the extender and prevented
authentication directly with the router. (This might be how extenders
work but that seems strange to me)
I identified it after I dug out a slow but known working AAO with an
Intel wifi card and which mysteriously failed to authenticate, so from
then I knew I was looking in the wrong place.

I managed to identify what turned out to be the real problem. It was nothing
to do with the ath9k and everything to do with my router.
I apologise for wasting your time but I am grateful that you bothered
Gerry
.. what was the problem?
