Getting your PSP on-line or tunnelling appears daunting at first, but it doesn't
have to be.  This FAQ will walk you through the PSP's Wi-Fi features, how to set
up connections on your PSP and even how to set up your own hotspot.

After reading section 1.2, check the following section depending on what you
are trying to set up.  If you need more help with networking terms, see section
5.1 for a short glossary. 

if you are trying to set up...

...your PSP to play multiplayer games on-line, see section 4.
...your PSP to play on-line games, see section 2.2
...Internet access on your PSP through a hotspot, see section 2.2

...your PC as a hotspot, see section 3.1
...your router or wireless router as a hotspot, see section 3.2

- 1.2. What are the PSP's Wi-Fi Modes used for?                                -
--------------------------------------------------------------------------------

Wi-Fi is a general term applied to wireless networking using a networking
standard known as 802.11b.  The PSP supports two Wireless Networking (Wi-Fi)
modes, called "Ad-Hoc" and "Infrastructure". 

Ad-hoc mode is for multiplayer games, Infrastructure mode is for internet
access for playing games designed to be played on-line (on-line games) or
general internet access.

Note: Normal multiplayer games are NOT the same as games designed to be played
over the internet (on-line games).  Playing multiplayer games over the internet
does NOT require the same setup as playing games designed to be played on-line.

See below for more detailed expLANations of each mode.

Ad-hoc mode
-----------

Used for: Multiplayer games, Possibly file sharing between PSP (in future).

Ad-hoc mode is for quick temporary connections between peers (i.e. multiple
PSPs, multiple PCs).  Ad-hoc connections don't need detailed information to be
configured prior to the connection being made and are similar to a Bluetooth
connection between cellphones.

Since Ad-hoc mode is convenient for quick, temporary connections, multiplayer
PSP games use ad-hoc mode.  After all, you don't want to have to go creating
network connections everything you play a multiplayer game with your mates, so
ad-hoc is the way to go.

Infrastructure mode
-------------------

Used for: Playing on-line games, internet access (browsing, listening to
RSS distributed content, downloading, operating software (firmware) Updates).

Infrastructure mode is for more formal connections, like connecting to the
internet.  You must set up a connection to the network your wish to
access.  This type of connection is the kind used in "hotspots", places that
have special hardware available for public connection.  Common locations for
hotspots are cafes, hotels, malls, libraries, etc.

Infrastructure mode can be used update the PSPs operating software (firmware),
browse the internet (operating software v2.0 or higher), listen to RSS
distributed content (operating software v2.6 or higher) or play some
multiplayer games online.

It is quite simple to create your own hotspot, all you need is a broadband
internet connection (depending upon your configuration dial-up may work, but
performance would not be adequate to play games) and either an Access Point +
Windows PC, a Wireless Router or a Router + Access Point.

Tunnelling
----------

Used for: playing multiplayer games which were not designed for internet play
on-line.

Tunnelling can be used to transport ad-hoc connections via the internet to other
PSPs.  This is totally different from an infrastructure connection because:

1) The PSP doesn't know its happening, as far as the PSP is aware, the ad-hoc
   connection is between two or more PSPs within normal operating range.
2) The PSP isn't connected to the internet.
3) Another device (in this case a PC running special software) is used to
   intercept he PSPs ad-hoc connection and relay it over the internet to the
   other players, who must have a similar setup.

Because the PSP doesn't know it's connection is being tunnelled, ANY
multiplayer PSP game can be played over the internet.  The downside of this is
that the PSP thinks the game is being played by users in the PSPs normal
operating range and therefore will not handle connection problems (i.e. Lag)
as well as a game that is designed to be played on-line.

- 2.1. Configuring Ad-hoc connections on the PSP                               -
--------------------------------------------------------------------------------

None.  PSP Ad-hoc connections by their very nature do not require any form of
setup by the user. 

The only setting of is the Wi-Fi channel number in Settings, Network Settings,
Ad-hoc Mode.  This should only be changed if you are experiencing interference
from other equipment or the channel you are using is not permitted in your
current location (different channels are permitted in different territories).

If you are wishing to play a multiplayer game on-online (tunnelling) an ad-hoc
connection, see section 4.
