What do you mean by forcing to N- mode ?

This is a bit weird, can you give us some more details ?
Configuration of the AP, connection type ( encrypted/open ) etc.
Also, please enable CONFIG_ATH9K_DEBUG in config.mk of compat-wireless,
and load the driver with the modparam debug=0x2000 and post the kernel log here.

I don't think this should affect ath9k, but still, please remove the binary
kernel module 'nvidia' when you are reporting kernel issues.
