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.

- 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.


--------------------------------------------------------------------------------
- 2.2. Configuring Infrastructure connections on the PSP                       -
--------------------------------------------------------------------------------

The PSP can support multiple Infrastructure connections, so you can have one
for home, work, etc.

To configure a new Infrastructure connection on your PSP, go to Settings,
Network Settings, Infrastructure Mode and select "-New Connection-".  A wizard
will appear that will walk you through the set up (use Left/Right on the d-pad
to move back/forward through the steps).

The following table contains some of the things you may be asked and what they
refer to.  Some of these settings may look daunting, but you can ignore them
in most cases, unless you have been told what to enter in them by the hotspot
provider or network administrator:

+------------------------------------------------------------------------------+
| Setting                         | Description                                |
+------------------------------------------------------------------------------+
| Connection Name                 | Enter the name that you wish the           |
|                                 | connection to be known by.  This has no    |
|                                 | relationship to the connection itself, but |
|                                 | simply exists so that you know what the    |
|                                 | connection was created for.                |
|                                 |                                            |
| SSID/Encryption/WEP Key         | Many Wireless LANs transmit their SSID     |
|                                 | (network ID) to identify themselves,       |
|                                 | others do not.  If you select "Scan", your |
|                                 | PSP will list all the SSIDs it can find    |
|                                 | for you to select.  If not, enter the SSID |
|                                 | of the Wireless LAN you wish to connect to |
|                                 | in the SSID field.                         |
|                                 |                                            |
|                                 | In the Encryption field, either select     |
|                                 | "None" or "WEP" depending on whether the   |
|                                 | Wireless LAN you wish to connect to is     |
|                                 | using WEP encryption.                      |
|                                 |                                            |
|                                 | If you selected WEP encryption, then you   |
|                                 | will be prompted for the WEP key.  Simply  |
|                                 | enter the WEP key of the Access Point or   |
|                                 | Router you wish to connect to.             |
|                                 |                                            |
| Address Settings/IP Address/    | Select "Easy" if you wish your PSP to      |

|                                 | TCP/IP networking settings.  "Easy" should |
|                                 | be chosen in most cases.  Select "Custom"  |
|                                 | if you wish to manually configure the      |
|                                 | the PSP's TCP/IP settings.                 |
|                                 |                                            |
|                                 | If you selected "Custom" in "Address       |
|                                 | Settings", you will be asked if you want   |
|                                 | to get a IP Address automatically,         |
|                                 | manually or via PPPoE.  Select "Automatic" |
|                                 | to let the PSP automatically get an        |
|                                 | address (if possible), or "Manual" if you  |
|                                 | want to assign the PSPs address manually.  |
|                                 | If you select "Automatic", then you will   |
|                                 | be asked if you wish to get DNS settings   |
|                                 | Automatically or Manually.                 |
|                                 |                                            |
|                                 | If you opted for Manual addresses then you |
|                                 | will be asked for the PSPs IP Address, Net |
|                                 | Mask, Default Router, Primary and          |
|                                 | Secondary DNS Servers.  If you opted for   |
|                                 | Manual DNS then you will be asked for the  |
|                                 | Primary and Secondary DNS Servers.  Note,  |
|                                 | you do not have to specify both Primary    |
|                                 | and Secondary DNS Servers, just Primary    |
|                                 | will do if you only have one DNS server    |
|                                 | address.                                   |
|                                 |                                            |
| Proxy Server                    | If you are behind a proxy server or        |
|                                 | firewall, you may need to enter the IP     |
|                                 | address of the Proxy server or hardware    |
|                                 | firewall, as well as the Port number it    |
|                                 | requires requests addressed to.  If you    |
|                                 | are not behind a Proxy, then you can       |
|                                 | select "Do Not Use".                       |
+------------------------------------------------------------------------------+

You will be presented with a settings list for you to check.  Simply press
Right one more time, then Circle to save your connection.

After the connection has been saved, you will be offered the option of testing
it.  Select Test Connection to let the PSP attempt to connect to the network
and access the internet.

--------------------------------------------------------------------------------
- 3.1. Configuring your PC with an access point as a hotspot                   -
--------------------------------------------------------------------------------

Requirements
------------

* Windows 2000 or XP PC with a broadband internet connection.  
* Available network adapter to plug access point into.
* 802.11b/g Access Point.  I recommend the Linksys WAP54G Access Point
  (http://www.linksys.com/products/product.asp?grid=33&scid=35&prid=608)
* Ethernet crossover cable long enough to reach from your PC to the 
  access point.  This may come supplied with your access point.

Administrative rights are required to perform this procedure.

WARNING: This method should not be used if your PC is connecting to a router or
other residential gateway.  If you are using a router then you should see
section 3.2 for how to configure either a wireless router or router + access
point.

WARNING: This method should not be used if your PC is connected to a Domain as
the wizard will break your connection with the domain.  Domains are only used if
you have one or more Windows NT/2000/2003 servers, therefore this should only
apply to business laptops or business networks.  You can check whether your PC
is connected to a domain by looking at the Computer Name tab of System 
Properties (Control Panel, System).


Setup the hardware
------------------

Connect one end of the crossover cable into the PCs available network card and
the other end into the access point.


Configuring Windows
-------------------

Run the Network Setup Wizard on the Windows PC to configure it as a software
router. This wizard can be found in Control Panel, Network Connections and is
accessed either by selecting “Set up a home or small office network” from the
task panel, or by selecting File, Network Setup Wizard.  

Technical note: The "Network Setup Wizard" in Windows will configure the network
card with the access point connected to the address 192.168.0.1, subnet 
255.255.255.0 and will provide internet access, DHCP and DNS services to any 
devices that attaches to it (via cabled or wireless network).

The following table contains an overview of the steps of the wizard, as well as
the answers I recommend choosing:

+------------------------------------------------------------------------------+

| Step 1-2                        | The first two steps of the wizard will     |
|                                 | describe the wizard’s purpose and show a   |

|                                 | before continuing. It is possible that     |
|                                 | that you will be warned about network      |
|                                 | adapters that have the cable disconnected  |
|                                 | at this point - if so, then ignore the     |
|                                 | warning and continue.                      |

You are shown a list of the selections you’ve made, simply confirm your 
selections to finish the wizard.  You may be asked if you wish to create a 
network setup disk, you can create one if you wish, but you do not need one.


Configuring the access point
----------------------------

Following the manufacturer's instructions, configure your access point as 
follows:  

Note: The names of options may not be exactly the same on your access point and
the steps for configuring your chosen brand of access point will be documented
in its manual.  Options not listed in the following table may be optional or
specific to your access point.

|                                 | for wireless networks, however that makes  |
|                                 | it a bit harder to connect to it from your |
|                                 | PSP (since you can’t just scan for it).    |
|                                 | Some people recommend turning SSID         |
|                                 | Broadcast off since it adds a little bit   |
|                                 | more security.                             |

|                                 | will be assigned to your home network by   |

|                                 | WEP is preferable since it provides a      |
|                                 | higher level of security.  Note: WPA is    |
|                                 | not supported by the PSP at the time of    |
|                                 | writing.                                   |

Testing
-------

If you have configured everything properly, you should be able to follow the
instructions in section 7.3 to configure your PSP to connect to your new
hotspot.


--------------------------------------------------------------------------------
- 3.2. Configuring your wireless router as a hotspot                           -
--------------------------------------------------------------------------------

Requirements
------------

* Broadband internet connection.
* Wireless 802.11b/802.11g Router compatible with your internet connection. I
  recommend the Linksys WRT54GS Wireless Router with Speedbooster if you have a
  cable or DSL internet connection that uses an Ethernet connection to your PC
  (http://www.linksys.com/products/product.asp?grid=33&scid=35&prid=610).
* PC/Mac to use to configure your router.
* Ethernet patch cables to connect any wired devices (PC, etc) to the router.  
  Note: you may need to change the Ethernet cable from your cable/DSL box for a 
  patch cable before you are able to get on-line, since in some cases crossover
  cables are supplied by the ISP.

Note: If you are using a router and a separate access point, the setup is much
the same except some settings will be on or duplicated on the access point.  
Simply connect the access point to one of the wired sockets on the router.
 
WARNING: It is crucial that you purchase a router that is suitable for your
internet connection, make sure when buying a wireless router that the router
supports the type of internet connection you are using (type of cable, type of 
internet connection).  If in doubt, check with your ISP before buying.


Setup the hardware
------------------

Connect your internet connection into your router and use Ethernet patch cables
to connect any wired devices to the router.


Configuring the router
----------------------

Following the manufacturer's instructions, configure your router as shown in 
the following tables.

Note: The names of options may not be exactly the same on your router and the
steps for configuring your chosen brand of router will be documented in it's
manual.  Options not listed in the following table may be optional or specific
to your router.

|                                 | for wireless networks, however that makes  |
|                                 | it a bit harder to connect to it from your |
|                                 | PSP (since you can’t just scan for it).    |
|                                 | Some people recommend turning SSID         |
|                                 | Broadcast off since it adds a little bit   |
|                                 | more security.                             |

|                                 | the letters 0-9 and A-F and write it down  |
|                                 | safely.  This key is required to connect   |
|                                 | to your hotspot with other devices. 128bit |
|                                 | WEP is preferable since it provides a      |
|                                 | higher level of security.  Note: WPA is    |
|                                 | not supported by the PSP at the time of    |
|                                 | writing.                                   |

|                                 | that you will allow to connect to this     |
|                                 | router. I recommend testing your hotspot   |
|                                 | before enabling this feature.              |

Testing
-------

If you have configured everything properly, you should be able to follow the
instructions in section 2.2 to configure your PSP to connect to your new
hotspot.

================================================================================

--------------------------------------------------------------------------------
- 4.2. Configuring your PC for playing multiplayer PSP games on-line           -
--------------------------------------------------------------------------------

Requirements
------------

* Windows PC with a broadband internet connection.  Windows XP with Service Pack
  2 strongly recommended.
* SUPPORTED 802.11b/g wireless network card.  I recommend the Linksys WPC54G 
  PCMCIA Card for laptops or the Linksys WMP54GS for desktop PCs 
  (http://www.linksys.com/products/product.asp?grid=33&scid=36&prid=611) and
  (http://www.linksys.com/products/product.asp?grid=33&scid=36&prid=621).
* Tunnelling software

Administrative rights are required to perform this procedure.

Note: Tunneling does not work at present with wireless routers or access points.
Don’t even bother trying to get tunnelling working with these configurations as
you’ll be wasting your time.

Note: Tunnelling requires fooling your PSP into thinking it’s communicating with
another PSP, not your PC.  Any wireless hardware MUST support Promiscuous Mode
(which allows a device to intercept packets not actually addressed to it), check
with your hardware supplier if you are not sure.  


Configuring Windows
-------------------

Note: For this walkthrough, I am using Windows XP Professional Service Pack 2.

* In Control Panel, Networks, select your wireless network adapter, right-click
  on it and select Properties.
* On the General tab, put a checkmark in “Client for Microsoft Networks” and
  “Internet Protocol (TCP/IP)”
* On the Wireless Networks tab, select “Use Windows to configure my wireless
  network settings”
* Press the Advanced button (not the Advanced tab)
* Select “Computer-to-computer (ad-hoc) networks only”
* Put a checkmark in the “Automatically connect to non-preferred networks”
  checkbox
* Press OK to close Advanced.

The next five steps may not be required, depending on your configuration.

* Click the General tab.
* Click on “Internet Protocol (TCP/IP)” and press the Properties button.
* Click “Use the following IP Address”.
* Enter “10.0.0.1” in the “IP Address” field and 255.255.255.0 in the “Subnet
  Mask” field.  
* Press OK to close Internet Protocol (TCP/IP) Properties

Finally press the OK button to save your changes.

If you turn on your PSP’s WLAN switch, load a multiplayer game and attempt to
host a multiplayer session, your PC should detect your PSP and show that it is
trying to connect to a network (SSID usually starts with PSP for PSP ad-hoc
connections)


Setup Tunnelling Software
-------------------------

Note: For this walkthrough, I am using Xlink Kai, available from 
www.teamxlink.co.uk

* Install Xlink Kai and register for a XTag username from the teamxlink website.
* Start the Kai Config Tool from the Xlink Kai Evolution 7 program group in your
  start menu.
* Select your wireless network adapter in the Network Adapter list.  If your
  network adaptor is not listed, you may need to put a checkmark in the “Show
  Dangerous NICs” checkbox.
* Enter your username and password in the “Default XTag” and “Default Password”
  fields and ensure the “Auto Login” checkbox has a checkmark in it.
* Ensure that the “Accept UI Connections From” list is set to “Any IP Address”
* You may find that setting the “Kai Port” and “Kai Deep Port” fields to “30000”
  may help, depending on your configuration.
* You may find that putting a checkmark in the “Enable PAT” checkbox may help,
  depending on your configuration.

If your PC is behind a hardware firewall or router, additional settings may be
required on your firewall or router, see www.teamxlink.co.uk for more 
information.


Hosting your first game
-----------------------

The first two steps may not be required by some titles, however some titles
(Ridge Racers particularly) refuse to host if your PC is connected to the PSP's
wireless connection when you select to host a game.

* Ensure Xlink Kai is closed.
* Disable your wireless network connection from Control Panel, Network 
  Connections.

* Start your PSP and ensure the WLAN switch is on.
* Launch the game of your choice and select to host a new game.
* Enable your wireless network connection from Control Panel, Network 
  Connections and ensure that it connects to your PSP.  This is simply a case
  of following the prompts Windows offers (it will tell you when connected or
  if it can see the PSP but isn’t connected yet).
* Start Xlink Kai and browse the lobby you require.
* Wait for other users.


Joining your first game
-----------------------

Joining a game is exactly the same as hosting, except you don’t need to close
and reopen Xlink Kai and disable/enable your wireless network connection.

- 5.1. Glossary of common wireless networking terms                            -
--------------------------------------------------------------------------------

As well as the terms mentioned in the Overview, the following table contains
some common networking terms you may encounter whilst setting up your PSP or
setting up your own wireless network.  Some of the later items (TCP/IP, Net
Mask, Gateway/Router, DNS, etc) are often provided for you if you are connecting
to another providers network, and are only required when setting up your own
wireless network.  Even then, many Routers, Access Points and similar provide
wizards to deal with many of the technicalities.

|                                | for wireless devices to a wired network.    |
|                                | Used to allow wireless devices access to a  |
|                                | wired network, and usually internet access. |
|                                |                                             |
| Router                         | A device that routes data between two       |
|                                | networks.  Useful for allowing multiple     |
|                                | devices to shared an internet connection.   |

| Wireless Router                | A Router that has an Access Point built in. |
|                                |                                             |
| Transmission Control Protocol  | A common format for transmitting data       |
| /Internet Protocol (TCP/IP)    | between devices.  As the name implies,      |
|                                | TCP/IP is the most common protocol for      |
|                                | internet connections.                       |
|                                |                                             |
| IP Address                     | On a TCP/IP network, each device is given   |
|                                | an IP Address to uniquely identify it.      |
|                                |                                             |
| Subnet Mask/Net Mask           | The Subnet Mask/Net Mask is used to         |
|                                | identify which part of an IP Address is the |
|                                | network ID (known as subnet), and which is  |
|                                | the devices address.  One of the most       |
|                                | common Subnet Masks is 255.255.255.0, which |
|                                | indicates that the first three numbers of   |
|                                | the IP Address are the Subnet ID and the    |
|                                | last number is the Host/device ID.          |
|                                |                                             |
| Default Gateway/Router         | When a piece of data needs transmitting to  |
|                                | a different subnet, the data is sent to     |
|                                | this address instead.  At the specified IP  |
|                                | address there should be a Router that has   |
|                                | been set up with rules how to reach the     |
|                                | desired subnet and will route the data for  |
|                                | you.                                        |
|                                |                                             |
| Automatic IP/Dynamic Host      | Many networks operate a DHCP server which   |
| Configuration Protocol (DHCP)  | will automatically handle the IP address,   |
|                                | subnet, gateway, DNS settings for you.  If  |
|                                | the network you wish to connect to supports |
|                                | this service, then you can simply set all   |
|                                | your IP settings to Automatic/DHCP and the  |
|                                | network you are connecting to will handle   |
|                                | the rest.                                   |
|                                |                                             |
| Domain Name Service (DNS)      | DNS servers handle translation of domain    |
|                                | names (i.e. microsoft.com) into their       |
|                                | corresponding IP address.  Without a DNS    |
|                                | server, it is very difficult to find any    |
