Right now, best what i can do, is to sync ath9k_htc code with ath9k as match as possible. There are many outdated duplicates, so eliminating them is the highest priority. May be the fix for crypt bug will one of this outdated duplicates. Please continue to use nohwcrypt=1 and report your results after one week. I'll try to do some more tests too.
About your usb issue. Theoretically it should not be caused by the driver. But after some experience with different usb controllers, i would not trust usb any way. It can provide critical delay for interrupt packets, so you will get speed drop on ath9k_htc for 10-30 seconds. May be host controller can't provide enough power: AR7010 based adapter would consume 200-300mA, and AR9271 100-200mA. Or not enough bandwidth. Or one of X^1000 usb bugs... i'll not be able to help here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1273392 Title: 0cf3:9271 [MSI FM2-A75IA-E53] ath9k_htc: AR9271 wireless device stops functioning Status in “linux” package in Ubuntu: Incomplete Bug description: A long time after a cold boot, my wireless connection starts dropping, will try to reconnect but will not come back again. When I'm in that state only a suspend, waiting a while and resuming gets my wireless connection back again. However, after that state it does not take long before it starts to drop again. WORKAROUND: I could not reproduce this problem again after setting nohwcrypt=1 on the ath9k_htc module.
