Wireless connection is dropped

[danfritz]

Hello,

When my Raspberry Pi boots up, the wireless profile is used and the wireless is connected with my router. After a while (not more then 5 mins) the wireless connection suddenly gets dropped. I then try to manually start and stop it again but I get the following error:

$this->bbcode_second_pass_code('', 'Aug 13 22:01:57 RasNAS systemd[1]: Stopping Connect With Lapeste...

My SSID is "Lapeste", so I dont really know what the issue is, im using the Edimax EW-7811UN 150Mbps Wireless Nano USB Adapter (normally the driver for the RTL8188CUS Chipset is included in archlinux). Only a reboot fixes the network (for a short time. Thanks!
