Gran Turismo 5 Prologue

How can I evaluate my own network connection environment?

Last Updated: Dec 25, 2007

There are many types of internet connection environments. We have identified environment levels typically used on a home network under 3 classifications, consisting of the type of connection, connection with network devices (NAT type), and Wireless (Wi-Fi) / Wired connections.

For details, please refer to the following pages.

- What kinds of internet connections are there?

- What types of network device connections are there (NAT type)

- Is there any difference between a wired connection and a wireless (Wi-Fi) connection?

Please note that depending on your internet service provider or the building of your residence, these may not apply in some cases.
