My psp keeps saying the server has timed out and keeps asking for a usi

That means that Sony's servers are down.

you have to downgrade your system to 6.20. thats the only supporting firmware ar psp could run on. and plus, the server is currently down and it will take time to fix it. i received this info from datel customer service via email. im guessing about 1 month for the ar server to work.

Find a more reliable connection then. Just that simple.
But before you do, these updates are not necessary. Just keep that in mind.

if it says that ea server is down, the ea network is down. you can't connect on the server for the meantime. just wait for a few hours or days there might be maintenance on their server.

try to go outdoor the try again if it says the same go to connection setting then adhoc then atomatic.

and try to scan 5 to 15 times.

wen the system accepts the dns setting the ur ready to go

if it is saying DNS error it is not a problem with the PSP, most likely a setting with your wireless router. or a problem with teh internet at the time of trying. check wireless settings on the PSP and make sure it has a number listed for DNS server.

You are most likely not close enough to the connection to receive a signal or you might have to change the security settings to allow your system to connect to the server

it says the server timed out it was working fine a mcdonalds

To browse over the internet, the PSP needs a DNS serversetting to link to the right server. Usually, the DNS info comes from the DHCP server (local Router or Switch or maybe a local DHCP server ?). If that is not the case, you should enter the DNS info manually in the PSP.

try a different wifi spot. ur wireless network isnt right fot the PSP
