I have same adapter, here are images of it:
http://wikidevi.com/wiki/TP-LINK_TL-WN822N_v2

but i don't have this problem. It will be interesting to have more 
information:
- please send output of "sudo iw dev wlan0 scan dump"
- information about your access point. if possible name of wireless chip 
in it. you can link it with wikidevi.com
- do you use power_save mode? you can check it with "iw dev wlan0 get 
power_save"

[Oleksij Rempel]

Can you please do some test:
- disable STBC on access point. You will probably need to edit 
hostapd.conf manually.
- change or disable encryption type.

[ath9k-devel] Tplink TL-WN822N drops out connections randomly on Arch Linux with Kernel 3.9.4 (Mark Lee)

[Mark E. Lee]

I couldn't find hostapd.conf on my access point.

I did however switch the algorithm from WPA2 to WEP and found that I no
longer lost connection during skype calls.

That kinda points at the rekey or the crypto handling in general.

Please find and enable hostapd logging on your AP. I've seen and fixed
bugs in freebsd recently where traffic would fill up buffers and cause
the EAPOL rekey packets to get discarded by the driver. Thus a group
rekey would fail, and the unit would be disconnected.

I reset my router to the default netgear firmware and found the issue
still continues. 

After seeing this message board post :
<https://bbs.archlinux.org/viewtopic.php?id=137643>
I set an option for ath9k_htc to "nohwcrypt=1". I will see how it goes
in terms of stability. In addition, I was wondering if one could tell me
what that option means.

[ath9k-devel] Tplink TL-WN822N drops out connections randomly on Arch Linux with Kernel 3.9.4 (Mark Lee)

[Peter Vágner]

Hello,
I do also have similar device and am facing a strange problem with it.
After booting up the machine I am unable to connect to certain wireless 
AP. That is an old Owislink WL5460 router set up in 2.4B+G mode with WPA 
encryption.
After connecting to another AP e.g. non encrypted AP made up of my 
Android phone or even encrypted AP created on an iphone I can then 
connect to the problematic AP.
I am on arch linux currently with kernel 3.9.6. The issue started 
happening as I have updated my kernel to 3.9.1. Previously everything 
has been working fine wor me.

Here are some more details

$ lsusb | grep Ather
Bus 002 Device 005: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

$ iw dev wlp0s26u1u6 get power_save

This is repeating over and over again until I connect to something else.
And then the final successfull connection to this AP looks like...

Hi Peter,

if it is regression, can you please do git bisect to find commit 
affecting your connection. It can be outside of ath9k_htc source.

[ath9k-devel] Tplink TL-WN822N drops out connections randomly on Arch Linux with Kernel 3.9.4 (Mark Lee)

[Peter Vágner]

Hello,
I am afraid I don't know how to do this.
Do I have to recompile the whole kernel testing each commit or should I 
just recompile the driver or even track firmware changes?

Can you please point me to somewhere where I can read on how to proceed?

Greetings

Peter

if you didn't updated firmware, then no.
You should recompile complete kernel.

use google. here is one example:
