Could it be due to the kernel version (i'm running on 3.18.21)? You probably need to adjust ack timings. I have some un-tested firmware support for this in the CT firmware, but I haven't fully wired it up to the driver. Someone with a bit of time and skill could add this to the ath10k driver if they wanted to. This commit has some details. http://dmz2.candelatech.com/?p=linux-4.0.dev.y/.git;a=commit;h=abd3ee5c4d297e56b854864624152f5704c5df20 Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
