Can you use the latest backports release and post the kernel log when the issue happens ? https://www.kernel.org/pub/linux/kernel/projects/backports/2014/01/17/ The ath9k-debug config can be used in backports: make defconfig-ath9k-debug && make && sudo make install Load the driver with debugging enabled: modprobe athk debug=0x7cb Sujith _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
