The PlayStation 3 system (slim and fat) uses wireless G. I think it's kinda stupid that it doesn't use wireless N but whatever.
The PS3 is Wireless g the other Playstation models do not come with WiFi
You can use router of G or N type and the same type wireless adapter. Of course you can use wireless N adapter with G-type router and reverse.
Yes.
802.11
Yes. It will operate at G speed.
yes it can
Any wireless cards that support Wireless-N will support Wireless-G. However cards that support Wireless-G will not necessarily support Wireless-N
If your modem has wireless interface, yes you can.
Yes, you can. Wireless N devices are reversely compatible with G networks.
no
PS3 has a G signal, but when you purchase your wireless router you are better off getting the Wireless-N-Broadband router for future connections to other devices. PS3 also is better wired than wireless and I found the signal test of the PS3 much better wired than WiFi. I also brought my Linksys by Cisco model no WRT160N wireless router at Best Buy and later saw a much better model at Sam's Club for the same price range that Best Buy had for twice the price
G or N .
