help psp network adaptor (clearer)

hi i jus bought a psp network adaptor and it had 100% connection on my psp wen i connected it.but it keeps sayin ip address timed out but wen i put the ip address in it says dns error plz help.

Ok this must be the router settings!

Go HERE or HERE and make sure the MAC address for the PSP isnt banned! some routers ban MAC addresses when they have false info or change on the PSP!

Also make sure you are typing in the correct WEP key if you have WEP!
