What Type of Wireless Does Sony PS3 Support?
Wednesday October 22, 2008
The Sony Playstation 3 video game console includes built-in 802.11g (802.11b/g) Wi-Fi wireless networking. It means you don't need to purchase a separate wireless game adapter to hook up a PS3 to a wireless home network.
PS3 does not currently support the newer Wireless N (802.11n) form of Wi-Fi. But that's still better than the Xbox 360, which offers no built-in wireless networking at all.

The neighbors share a internet connection through a wireless linksys G, their ps3 works fine but we get a lot of extra connected people that we would like to limit through a security. When we apply this the ps3 can not connect. Is this a compatibility issue?

You can setup WPA2 on the PS3. I have a PS3 60GB and I am running MAC filtering and WPA2 using a Linksys WRT54G wireless router.
Is there a pcmia slot on the Playstation 3 to add a more robust wireless card? Or is
there some other add on solution to improve reception? My Buddy’s PS3 is upstairs, his router is downstairs. Signal is week. Thank you.
To Dave:
The PS3 has a wired ethernet port. You can either run a cable or get a wireless _bridge_. A bridge connects a wired ethernet component to the wireless network. By having an 802.11n bridge connected to the PS3, you can take advantage of 802.11n networks (if your main router supports it) and in all cases, you can move the bridge around more easily to optimize the reception.

I have Wep3 for security. Does that work with PS3?
