Open the "Settings" option on the far left side of the PlayStation 3's main menu. From here, choose "Network Settings."
Open "Internet Connection Settings." From the list of options that appears, choose "Easy," followed by "Wireless."
Select the "Scan" option. When the PlayStation 3 returns a list of the names of available wireless networks, select the name of your home's network.
