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
"iwlist wlan0 scan" output for this AP:

I unloaded ath9k, then loaded ath9k driver in debug mode on the
problem client ar9102 router. Here is the dmesg output after the
unload/load.
