DHCP means Dynamic Host Control Protocol. For any two devices to communicate with each other on a network, their communication has to be governed by a set of parameters that includes IP addresses. The PS3’s DHCP technology configures these parameters automatically, but at some point you may require your own manual settings -- for example, if the PS3’s DHCP system fails to work, or you need a static IP address to access the PlayStation network.
Turn the console on and wait for it to boot up. Once it's ready, select "Network Settings" under the "Settings" tab in the main menu.
Choose “Internet Connection Settings.” If you have an active Internet connection, at this point you will receive a prompt telling you that you will be disconnected. Choose “Yes” to disconnect.
Choose either “Custom” or “Easy” at the next page. “Custom” allows you to configure your own settings rather than using the default. Inexperienced users should avoid using the “Custom” setting.
Select either “Wireless” or “Wired,” depending on the type of connection you have. The procedure remains the same for either choice.
Select “Auto-Detect” operation mode to arrive at the “IP Address” setting. You now have the following options: “Automatic” means the DHCP server will determine addressing information for your console; “Manual” means DHCP is disabled and you must enter the information yourself. The last, “PPPoE” allows you to use a PPPoE connection, a network layer protocol that allows you to establish a secure point to point connection between your console and another.
Choose “Manual” and enter your settings as follows:
“IP Address:” enter your static IP address. Consult your Internet provider for your static IP address.
“Subnet mask:” 255.255.255.0
”Proxy Server:” Do Not Use
”UPnP:” Enable if you have a router that supports UPnP. Otherwise, Disable.
Press the "X" button to save the changes after you have finished inputting them.
