How do I access the internet with a PSP?

there's a web browser on there. use that. you'll have to configure the WiFi first, and, of course, you'll need to have WiFi available at your location.

What is WiFi? Sorry, I am not literate with that stuff.

Wireless 802.11 Internet access. If you're at a location with a "WiFi Hotspot", or something like that, you can use it on your PSP. If there's not wireless access there, you can't use it.

I found one in Stanhope, but I'm in Hackettstown. Is the "Hotspot" a store? What does that mean? Teach me Gameboy.

a hotspot is a place where you can get wireless internet. the closest place to you that has it i think is panera
