Great to hear!

Do you mean iwconfig? iwconfig does not tell you MCS (HT or 802.11n rates)
and you will see 1 Mbps rate when that is used. To get more accurate MCS rate stats
you now have to use iw:

http://wireless.kernel.org/en/users/Documentation/iw#Gettingstationstatistics

sudo iw dev wlan1 station dump

This is still being worked on by mac80211 drivers, so you won't see the last TX rate yet
but hopefully soon.

"link not ready" just means that you haven't associated yet. I know -- this is a bit cryptic,
but in a way its right, and its certainly correct for ethernet.

Looks good.

Nope, what is happening here is the kernel is not getting the regulatory domain. Please
show me the log of you compiling and installing CRDA (make clean; make; sudo make install).
Then, as per CRDA debugging page [1] you can debug commmunication between the kernel and
crda by running:

sudo udevadm monitor --environment kernel

But I want you to do this by first doing this:

sudo rmmod ath9k mac80211 cfg80211
sudo dmesg -c > /dev/null

Then on one terminal have open 'sudo udevadm monitor --environment kernel' and in another
run:

sudo modprobe cfg80211
sudo dmesg -c > log

Send me that log, and also the output from the terminal with the udevadm running.
