Instructions
Reduce the distance between your PSP and the wireless router you use to connect to the Internet. If possible, play in the same room as the router. Make sure there are no stone or concrete walls or heavy solid objects between your PSP and the wireless router; these can weaken the signal, leading to a slow connection.
Make sure that other computers or devices are not using up all the bandwidth (data flow) of your connection. Don&'t try to play PSP games online at the same time as you are downloading large files or streaming music or video over your connection. If you share the connection with other gamers, take turns with the connection and respect each other&'s playing time.
Simplify the connection between your router and modem. If your Internet connection involves a multi-stage arrangement of modems, relays and routers, cut down on wires and devices that can weaken the signal. Ben Barrett, gaming salesman in New Zealand, explains: "The strongest Internet signal comes from a combination modem and wireless router. If you use separate devices, connect them with a short wire without other devices in between or branching off from the modem."
Upgrade your Internet connection, which simply may not be fast enough to support the high-speed access demanded by the PSP. If your connection is not at least 512 kbps (kilobytes per second), ask your Internet service provider about upgrading the service or switch to a provider that offers this speed.
