root@Easy-link:/# cat /sys/kernel/debug/gpio 
GPIOs 0-29, ath79:
 gpio-8   (USB power           ) out hi

 gpio-20  (sd-reset            ) in  lo
 gpio-27  (elink:green:system  ) out lo

First discover the SID.

ifconfig wlan0 up
iwlist scan | & grep M-MINI
 ESSID:"M-MINI_030DA4"
ifconfig wlan0 down

Now we may create a connection profile.

#auto wlan0
iface wlan0 inet static
        address 192.168.1.100
        wireless-retry 20
        wireless-channel 6
        wireless-essid M-MINI_030DA4
        wpa-ap_scan 1
        wpa-key_mgmt NONE
        wpa-ssid M-MINI_030DA4

And then, connect.

ifup wlan0
