Hi

First  : the target path asked in your script works only with aboslute path.. if you try a relative one, the script will failed (not a big deal to fix actually)

Secondly : you wrote in the Reade me that the wireless is working... I cannot make it work! I tried no encryption,  wep, wpa.

I can sse that the signal level is 0..
