How to set your psp internet up?

I got a psps today and want internet on it,while we were riding around in the i kept trying to connect but wasnt successful it had scanned for me. Can someone tell me how to be successful using someones connection because at the time i cant get a wireless router,please guide me through step by step.

BEFORE THE STEPS MAKE SURE THE wLAN SWITCH ON THE LEFT SIDE OF UR PSP IS ON!!!!

After borrowing someones wireless access point,assemble it.Then in ur psp,under 'Settings' go to 'Network Settings'.Then two options will appear. i know the infrastructure way only,so select 'infrastructure mode' and then select 'New connection'.after that if u know the information about ur access point(ex :SSID)u can use the 'Enter manually'option,otherwise if ur lazy to enter it or u dont know anythin,without worryin select 'scan'option.after u finish this process,the psp should be able to detect the access point.and then go to the 'internet browser' under 'Network' and type the website u want to visit,on the address bar above andhave fun,but sometimes even in internet browser u have to re connect the connection.still if u have a problem then there must be a problem with ur accespoint or something else.
