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 
 
* 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

* 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 **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.
