PS3 Wireless Capability
With the exception of the original 20GB model, the PlayStation 3 video game consoles, the PS3 Slim consoles, and the PS3 Super Slim units all include built-in 802.11g (802.11b/g) Wi-Fi wireless networking. You don’t need to purchase a separate wireless game adapter to hook up a PS3 to a wireless home network.
The PS3 doesn’t support the newer Wireless n (802.11n) form of Wi-Fi that is included in PlayStation 4 consoles.
PS3 vs. Xbox Networking Support
The PS3 networking capability is better than that of the Xbox 360, which offers no built-in wireless networking at all. The Xbox has a built-in 10/100 Ethernet network adapter, but a wireless connection requires an 802.11n or 802.11g adapter that must be purchased separately.
