WiFi Issues, TL-WN822N v.2, stays 'connecting...'

Hello,

I have a problem with my WiFi. I use the TP-LINK TL-WN822N v.2 USB WiFi Adapter.

# lsusb

Bus 003 Device 007: ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287]

I guess it uses the ath9k_htc driver

# lsmod

ath9k_htc              56055  0 
ath9k_common            8550  1 ath9k_htc
ath9k_hw              397498  2 ath9k_common,ath9k_htc
ath                    19483  3 ath9k_common,ath9k_htc,ath9k_hw

# dmesg | grep usbcore

[    3.580221] usbcore: registered new interface driver ath9k_htc

I work with Cinnamon and NetworkManager on

# uname -a

Linux PCNAME 3.15.7-1-ARCH #1 SMP PREEMPT Mon Jul 28 20:06:17 CEST 2014 x86_64 GNU/Linux

It seems, that all is working pretty well, because I'm able to see SSIDs in my range, but when I try to connect with my home wifi (WPA2), I get asked for the passphrase, which I enter correctly, but the NetworkingMangaer-Applet just stays on 'connecting ...'
For testing I tried to connect to my mobilephone hot-spot (no security) and here I got no problems. Also I have no issues to connect via lan cable. Usually I use DHCP put also when I give my pc static IP it wont work.

The WiFi Module is loaded:

What could be the problem, why can't I establish a connection?

Thnaks for your help!
