Hi,
I am using ath9k_htc with my TL-WN821N.
The problem is when it transfers with max speed (should be 300Mbps but not
with ath9k_htc, this could be another story) for some while (eg. 10 mins),
the dongle gets really hot and it hangs with no blinked LED. At this time,
there is no response from the dongle anymore. I have to plug in/out to make
it get normal.
But everything under windows is just fine. With max speed (300 Mbps) do
some ftp for 1 or 2 hours, everything is just fine.
I am so sure that the hang is because of the chips getting too hot. I
bought 2 pieces of heat sink and attached them on the two chips. And the
transftering lasted almost 1 hours till now (normal case it would die in 15
mins.), even the heat sink is really really hot.

Bus 002 Device 006: ID 0cf3:7015 Atheros Communications, Inc. TP-Link
TL-WN821N v3 802.11n [Atheros AR7010+AR9287]
kernel version
Linux CC 3.1.8-1-ARCH

Beeender

Can you install the latest compat-wireless package from:
http://linuxwireless.org/en/users/Download ?
Debugging has to be enabled by using these flags in config.mk:
CONFIG_ATH9K_HTC_DEBUGFS=y
CONFIG_ATH_DEBUG=y
For generic instructions, please see:
http://linuxwireless.org/en/users/Drivers/ath9k/debug
And then, please post the output of:
cat /sys/kernel/debug/ieee80211/phy#/ath9k_htc/modal_eeprom
cat /sys/kernel/debug/ieee80211/phy#/ath9k_htc/base_eeprom

I would like to add some report to this thread
http://www.mail-archive.com/ath9k-devel at lists.ath9k.org/msg07512.html
I just don't know how to add answer to old email discussion. I am not
familiar with emailing list. Sorry for that.
I have the same issue as described in thread
http://www.mail-archive.com/ath9k-devel at lists.ath9k.org/msg07512.html
I use Fedora 16. Output for lsusb:
Bus 001 Device 003: ID 0cf3:7015 Atheros Communications, Inc. TP-Link
TL-WN821N v3 802.11n [Atheros AR7010+A9287]
uname -a
Linux damianos 3.2.6-3.fc16.x86_64 #1 SMP Mon Feb 13 20:35:42 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux
I tried other distors, effect is the same. I start copy sth via ftp and
after 25-50 second wi-fi dongle is hanging.
