In the wifi router you have to configure what kind of connection you want.
So you have to decide the ESSID name, the type of network authentication, wep or wpa encryption, the encryption key or password for one of this, and others...
then in the wconection.sh you have to put the ESSID name in the form "name" and the encryptionkey in the form myencryptionkey (in this case without the "")
and be sure of the existence of /opt/wlan0.sh
In case of wifi-radar it detects all nearby wifis automatically, except those that are hidden in the wifi router configuration, in this case you have to create a new connection with the NEW button and put the hidden ESSID name and all the other parameters.
