Common PSP Wifi Problems and Fix Procedures

Numerous problems can be encountered when attempting to connect a PSP to a wireless network. The first issue occurs when the PSP is completely unable to connect to the network. In this case, the first fix that should be attempted is to turn off power saving by going to Settings, Power Save Settings, and turning off WLAN Power Save. If the problem persists, the next step is to confirm that the right network is being connected to by verifying the SSID and that the correct security key is being used. Following this, every device in the wireless network should be turned off and then turned back on again, including access points, routers, and modems. The problem can also be caused by having too many devices on a wireless network, and so other devices on the network should be disconnected. Finally, the network connection should be verified by accessing the internet through another device, such as a computer.

Another common problem is that the PSP can connect to the network, but cannot access the internet, or that the PSP can access the internet, but not Sony's servers. The most likely problem in these cases is that a router firewall is blocking communication. To solve this, certain ports must be opened in the router's firewall. For PlayStation Network and SCEA game servers, these ports include the TCP Ports 80, 443, 5223, and 10070 - 10080 and the UDP Ports 3478, 3479, 3658, and 10070. To find out how to open ports in a router, the router manufacturer should be contacted.

The last problem that may be encountered is an intermittent or unreliable wireless connection. To fix this, the signal strength must be improved. One way to do this is to simply move the PSP closer to the wireless router. This will improve the connection quality in almost every case. If this is not possible, interference should be eliminated. Physical barriers between the PSP and the router should be removed, and other sources of radiation, such as microwave ovens, florescent lighting, Bluetooth enables devices, 2.4 gigahertz cordless phones, high power sound systems, televisions, computer monitors, or any other source of Radio Frequency (RF) interference should be shut off or removed.

If none of these fixes work, the PSP should be updated to the latest firmware from Sony. If problems continue to persist, Sony technical support should be contacted as the PSP may be defective.
