Internet on the psp

To get internet on your psp you need to have wireless internet acess, on my comp i have a Netgear router it has 4 ports to hook things to the internet.
Is there such a thing to plug into one of the ports to make the router wireless?

Why can't you just go to a place that has a wifi around it?

thats a good point but it would be useful to have acess all the time.

Can you acess any site on the internet in web browser?

No, just ones that have been approved by sony.

Do you know if there is a list or something to know which sites?

no you can try to access any site. just remember that the browser has limited abilities so most sites wont completely work correctly

i suggest using bookmarks and storing them in your psp, its much more faster than just manually typing it in
