Thank you so much for the reply Shafi. That worked for me.  I'd like to suggest to whomever maintains the site  http://wireless.kernel.org/en/users/Drivers/ath9k/debug
to add those instructions on how debug by changing parameters in the config.mk file. While searching the web I have read that several wireless researchers cannot figure out how to enable debugging in ath9k and view the /sys/kernel/debug/ath9k/phy0 files.


Thanks again for the response, it's greatly appreciated!!!

Iv been looking into using the rcstat file but I cannot seem to locate it in the system for some reason:
Rcstat file is used to know at what MCS rate that the ATH9k received the frames and you can find more details like PER (Packet error ratio), success and retries info. http://wireless.kernel.org/en/users/Drivers/ath9k/debug



It is supposed to be located here: /sys/kernel/debug/ath9k/phy0/rcstat
After issuing the command: 'mount -t debugfs debugfs /sys/kernel/debug/' but it does not work for me.  My system does not have /sys/kernel/debug/ath9k only /sys/kernel/debug with no ath9k but, I am positive that I am using the ath9k driver? Thank you for any responses?
