WiFi Cubox-i 4pro

Using the Cubox-i4pro once I set the ssid from the WiFi setup and click save changes there is neither WiFi or LAN any longer. Any ideas?

Just wait 30 seconds, then cut power and turn it on. Should work!

Thanks for the quick response, but no joy. I have attempted several times without any success. Here is what did work for me.

I have edited the /etc/network/interfaces file by adding:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-mode managed
wireless-essid my_ssid

For some reason when I use the Network Configuration page the result is no Lan or WiFi connection. I have been very careful to conduct a WiFi and network scan to assure I am not missing the possible IP address. Please suggest any trouble-shooting ideas I can try.
