What does the psp use for online playing?

okay thanks i kinda don't want to reconnect everthing couse im lazy but still wifi...

so if i switch it to wep and then switch it back wpa will everything work again?

so does the computers and printers and that stuff reset itself?

so what if i have some printers and some other computers and a ipod touch that are hooked up to the wireless will i have to change those to or will they go automaticly?

also what is the difference between wpa and wep?

so does it really make it so you have to reconnect everything that is connected to the wireless connecter and where do i go for settings on my wireless connecter?

i have a ds lite so isnt that a different setting then the dsi? What does the ds lite use? the dsi uses wep but not the dslite

yeah if anything. So any more info of what to do? i really want to start playing online. with some games im going to get and games i have now.

i have a ds lite thinking maybe to get a dsi but most likely not.

I've looked everywhere and it just doesn't work i have a linksys wrt54g model. is there anywy to connect my ds through my wii cause my wii internet works fine. thanks if you need more info just ask
