smart firewall can't see my wireless device in trust control because i use mac id spoofing

i use mac id spoofing because i download from public wifi and sometimes they grab my mad id and kick me off

 

so all i have to do is spoof a new mac id and reconnect.

 

my question is...

 

is the smart firewall working properly?  I can't set trust controls for the network i am on because the device is not seen>

 

yet other places do see a wireless card there in setting.

 

thanks in advance.
