Then copy the PSP folder (inside 1.0 or 1.5 folder) to the root of your PSP. If you have firmware 1.5, install the 1.5 PSP folder, and if you have 1.00 or 1.51+, install the 1.0 PSP folder. Then open the PSP folder, then Game, then wifi controller on your PSP. After this, click on wifi.cfg and edit it with notepad. Replace "192.168.0.10" with the IP address you copied earlier.
