Howdy.
This is talking to a WDNR3300 second interface, which is a G only
broadcom chip, using wpa2 encryption. I have seem similar problems
with an Atheros AP too... but wanted to document the AP in question.
I do not believe the encryption is a factor, I've seen similar
problems with no encryption. These tests were performed using a
serial port console, none of the ethernet cabled ports of the router
were populated.
Basically the signal seems to retrain rate a lot, going down to 1Mbps
rate pretty quickly. Plus then I find ping times keep climbing until
it either retrains again or I have to rmmod and insmod the ath9k
driver.
Using the latest OpenWRT trunk with kernel 2.6.28.2 and
compat-wireless ath9k 2009-02-02. This is a real time session log,
from cold boot of the hardware with wireless off, then starting a ping
and enabling the driver. see here: http://pastebin.com/d5334f384
I know some prefer not to visit website logs, so I'm posting excerpt
here. Pay attention to the ping sequence numbers, note how the
unloading of the driver and reloading temporarily helped. But then
started to climb again. I again encourage you to view the full
session at the pastebin site.

Yha, sorry about that; Ok, I'm going to start this over and focus on
the retrain and rate issues. Both routers are running the same
chipset with an ar9102, the AP using proprietary madwifi and the
client running ath9k.
Router / AP: D-Link DIR-615 rev C1 running firmware 3.01. Mode:
802.11n only. Channel: 2.462 Ghz channel 11. Channel width: Auto
20/40 Mhz. Encryption: WPA2/AES. wireless chip: ar9102
Router / client: Trendnet TEW-652BRP hardware running OpenWRT trunk
with compat-wireless 2009-02-02 on Linux kernel 2.6.28.2. wireless
chip: ar9102

Ok, a fresh pastebin with expiration set correctly. This was against
a Netgear WNDR3300 Broadcom G chip (2nd chip in this router, the main
chip was set to NA mode). This time the connection was more stable,
but you can see how it connects at 5.5Mb/s and quickly drops to 1Mb/s.
I've managed to connect at 24Mb/s and see it quickly drop to 1Mb/s on
various attempts.
the ath9k was loaded in debug mode, I included the output. There is a
bit to wade through, but hopefully it details the issue.
session here: http://openwrt.pastebin.com/f1795e978
Thank you.

Can someone please try client (station) mode on an AHB bus AP81
router? The slower MIPS CPU or even how we initialize the
ar9102/ar9103 chips could be factors.
if you are a serious ath9k developer (the ones with the Linux Kernel
skills) and need a router, please contact me.... I will personally
send you a router for free to advance the Linux router cause. OpenWRT
is the real deal, please get involved. Being stuck on binary drivers
with a 3 or 9 year old kernel is impacting greater society. We want
to be _ahead_ of the technology curve - this time.

I can not even associate my ath9k(AR9130) to a Trendnet652 under n-mode, g/n mode is OK but ath9k client can only get 1Mbps(so, it's likely the g-mode was used). I have added ieee80211n to hostapd and ht_capab was added there as well.

Can someone please try client (station) mode on an AHB bus AP81
router? The slower MIPS CPU or even how we initialize the
ar9102/ar9103 chips could be factors.
if you are a serious ath9k developer (the ones with the Linux Kernel
skills) and need a router, please contact me.... I will personally
send you a router for free to advance the Linux router cause. OpenWRT
is the real deal, please get involved. Being stuck on binary drivers
with a 3 or 9 year old kernel is impacting greater society. We want
to be _ahead_ of the technology curve - this time.

The ping time climbing seems fixed. Thank you. I assume it was this
change related to the RTC clock of AR9100. Reference change:
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commitdiff;h=0cee9809976b35d7bd9eeb6bb7f32b8ac3fcd86d
On kernel 2.6.28.6 with compat-wireless 2009-02-19. All who have put
the AR9102 in client-mode seem to watch it quickly degrade to 0 or
1Mbps rate... which I do not see on a laptop with AR5418 MiniPCI card
using same compat-wireless.
Sujith or other developer tried ath9k on AP81 platform routers in client mode?
Thank you.

I haven't tried using ath9k on routers. Do you use OpenWrt ?

Yes. For OpenWRT, I have been attempting to identify and locate every
retail router that uses AR9130/AR9132 paired with
AR9102/AR9103/AR9104/AR9106 chip. I speculate this is known
internally at Atheros as the "Howl". I have compiled a list of known
retail routers: http://wiki.openwrt.org/AtherosAR9100
The GPL downloads for these routers includes binary kernel 2.6.15
madwifi customized by Atheros for which I have been unable to find
complete open source code. The madwifi drivers emit these messages:
ath_ahb: 0.9.4.5 (Atheros/multi-bss)
Howl Revision ID 0xb5
wifi0: Atheros AR9100 WiSoC: mem=0xb80c0000, irq=2
Some routers also indicate "Howl Revision ID 0xb4" we have encountered.
These routers are MIPS CPU instruction set and use the AHB bus for the
ar910x chips. We have AP mode working with ath9k, but it is erratic
and retrains rate every few seconds. Even if the retrains stop for a
while, relatively slow throughput (1.2MB/s WAN to LAN is best I can
achieve over wireless with 2009-02-19 compat-wireless). Client mode
consistently drops to 1Mbps rate immediately after association as
shown by iwconfig (have tried against both Atheros and Broadcom N and
G routers).
Currently, OpenWRT is fully installable (no need to open hardware) on:
D-Link DIR-615 revision C1 (ar9102)
Trendnet TEW-632BRP (ar9102)
Trendnet TEW-652BRP (ar9102)
Planex MZK-W04NU (ar9103)
There are other brands and models of the commercialized AP81 platform
that we have been able to run OpenWRT with the addition of hardware
access to the internal console serial port. Work is still underway to
assimilate them fully.
I can only theorize that there are possible issues with ath9k on the
slower MIPS CPU environment, some special registers these AHB chips
require initialized, or ??. Note that CPU usage itself has been
resolved as an issue, we do not see it go beyond 10% usage (there was
an issue we had earlier with LED, but OpenWRT has patched to disable
this for now).
If there is any way I can help you familiarize yourself with OpenWRT
compilation environment, please let me know. If you would like
specific debug tests to be performed, please provide instructions.
Thank you for your attention on the situation.
