A wireless connection on the PlayStation 3 allows for game and movie downloads, internet surfing and online play. There is no need to use an Ethernet cable to get started. Depending on the model of the PlayStation and the type of wireless router you have, the setup can be a little different. If your router has a security key, keep it handy before plugging in a new PlayStation. Some wireless routers require a computer to enable new access points, which can be done by simply checking the settings of your wireless on a home computer.
Turn on the PlayStation 3 and use the controller to access the "Settings" menu section. Scroll down the list to "Network Settings" and press "X." In the new menu, select "Internet Connection Settings."
Select "Yes" to the confirmation screen saying you are disconnected from the Internet. A series of questions will follow. Select "Easy" connection setup and then "Wireless" for connection type.
Select "Scan" to scan for access points in your area, and select your own from the resulting list. Check the back of your router for the SSID number to make sure. Some models of the PlayStation 3 give you the option of entering an SSID manually by typing it in with the on-screen keyboard if you wish.
Select the security setting that matches your router. For example, if your router has a WEP key security, select "WEP." If there is no security on your network, select none.
Type in the encryption key code that matches your security settings with the on-screen keyboard. This will appear in stars on the screen. Select "Save settings" to complete.
Test the network by selecting "Test Settings" from the next menu. If there are further problems, check the settings of your router on a nearby computer. If all access points are taken, disconnect another wireless device to free a space and try again.
Networks with a proxy server or multiple IP adresses might require further steps in the PlayStation menu. Simply follow the extra steps with the information it requests, such as the IP address.
