Well for me there was a few errors i changed the path to were the wifi drivers are it loaded up but it fails to add the mac addresses for purging i couldnt even purge every one on the network ......

For me the old script was a better way to go not so much of a fan for the GUI just my view thats all ....

great job thou ....

EDIT

Restarted phone and moved script to /home/user/ and all seemed to work well ....

cheers
