Hi all!
I'm using AR5416-based (TP-Link TL-WN861N) n-card with ath9k
(compat-wireless-2009-01-25) with 2.6.27-rc6 kernel on ARM (Intel XScal
IXP425). We have two Netgear n-routers, but the connection speed
(measured by simple FTP transfer) doesn't seem to be 'n'. ~2 weeks ago
there was a thread on this list about n speed, I made a quick compare
between my logs and the logs found on the list, and noticed that my card
never operates on 5Ghz frequencies.
(The card is switched to DE regulatory)
Do you have any idea? What is wrong?
Here are the logs:

Your logs showed:
> phy0: Atheros AR5416 MAC/BB Rev:2 AR2122 RF Rev:81: mem=0xc4900000, irq=27
AR2122 is a single band 2.4 GHz 2x2 MIMO radio -- it has
two integrated 2.4 GHz radios, supports both 20 MHz and 40 MHz
bandwidths.
> Do you have any idea? What is wrong?
You reported two things:
1. Not getting good throughput
2. No 5 GHz.
As for your first issue can you confirm you have set up your access points
in 802.11n mode, and see if you can enable HT40. If you have no legacy products
(802.11bg) I would recommend to go 'Pure N' or aka 'Greenfield'.
As for your second issue, your concern about not getting 5 GHz channels,
your card seems to be single band so it does not have any 5 GHz radios.
You can always install iw and run 'iw list' to confirm. Not all cards are
dual band. Dual band card are quite rare, specially AR5416 cards from what
I have seen.

Instead of logs please show iperf tests for now, from the station using
the ath9k driver to a box connected directly to an APs through ethernet.

I have one of those routers too; I think it is interesting to note
that your Netgear WNR2000 is an AP81 router platform that has ar9103
chip radio with 3x3 MIMO. It actually is capable of running OpenWRT
with the ath9k driver... although you would need to solder in a
3.3volt rs232 serial port (3 easy wires) and use tftpboot to load
OpenWRT (currently we have not devised a way to flash newer OpenWRT on
to the router). The default netgear firmware on the router uses a
madwifi for kernel 2.6.15 we have not located the source code for.
