Hi there, i just got a new PSP and have been unable to get a net connection on it so far due to the fact that i am using a Mac pc & i dont have wireless internet.
However... i have found that if you go to settings, then go down to network settings, then click on 'infrastructure mode' then just click 'connection 1', then click the right arrow, then click 'scan' and it will come up with wireless connections around your area... Then it will list them, but i think you can only use it if under security it says 'none' because otherwise you have to put a code in to be able to use it.
so far i havent been successful, most people have security.
