@legosithlordyusei12 if you can't plug directly into your cable modem, yes you need a router. those networks your ps3 are picking up are wireless, cable modems don't put out wireless connections until they are combination router and modems.

i dont understand anything ;(, OKOK. I got PC with XP and laptop with vista

Under my computer-table i got an modem (maybe) and the name is A-link WLAN. (maybe WLAN) i got in my PC a wired connection but in my laptop its wireless.

So how can i got two connections from modem??? And i even dont know my WPA and when i opened this laptop first time, it connected to internet just automatic.

But when im trying to do this with my PSP, i need a WPA key? Why is that?

You maybe know how to find my WPA? TY
