I've managed to find the problem. The script works fine, I've found what was 
wrong with ifconfig.
My router filters access to the machines that don't have their MAC address on 
a list.
I had assumed that the MAC address was the same either if I used the USB Wifi 
device or my ethernet connection. It turns out that they are different and 
not machine based but on the MAC of the device used to connect.
So now everything works as it should.

Thanks for your suggestions,
