Status WLAN0:
ip link show wlan0

SSID's to connect:
iwlist wlan0 scan
or
iwlist wlan0 scan | grep <SSID>

To ensure that the WLAN is operational all the time and no „Power-Save“ is kicking the device out of the LAN while idele disable the Power-Save option of the Edimax-driver.

For that create a conf-file:

vi /etc/modprobe.d/8192cu.conf

And insert the following content:

options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

Get rid of ifplugd, nice feature but nasty when the tun0 interface of chilli comes up and everything else goes down:

apt-get remove ifplugd

Enrich the intefaces file with static configuration for eth0 and WLAN0 (Remember this RASPBERRY will run as a Server!!!):

/etc/network/interfaces

# lo Loop-Back Interface Config
auto lo
iface lo inet loopback


#ETH0 Config
auto eth0
### ETH0 DHCP Config
#        iface eth0 inet dhcp
