You can also try to bridged network on the WinXP machine

Go to Control Panel, Network connections. Highlight the Local Area Connection and the Wireless Network Connection, right click, and then choose Bridge Connection. This will allow you to use the Win XP machine to bridge the network between the PS2 and the router. Then, you'll need to connect a crossover cable between the PS2 and the WinXP machine.

hi maldita,

for wired connection
* connect a cable between the router and ps2
* make sure that ps2 set to obtain an ip automatically

if your PS2 still not capable to have a wireless connection, kindly check this link http://www.broadband-for-ps2.co.uk/ps2_ ... etwork.htm for suggested wireless game adapter.

for wireless connection
* configure your ps2 with the same wireless settings of your router, such as SSID, CHANNEL and wireless security if enabled
* make sure that ps2 set to obtain an ip automatically
* then test the connection

some tips from Sony

1. Check your cables:
Wrong type of cable?
You might have accidentally used the wrong type of network cable to connect your PlayStation®2's Network Adaptor to your router. Make sure that you're using a straight through, or CAT5 network cable and not a crossover cable. For more information about the different types of network cables, see our related articles.
Cables not plugged in correctly, or faulty?
Check the ports that you've plugged the cables into. You should see two small lights above each port. If the cables are plugged in correctly, and everything is switched on, the left hand light should light up indicating that the cable is connected properly. If the light does not light up, double check that your PlayStation®2 and router are switched on, then check that you're using a straight through cable to connect the two. If you still have problems, it could be that your network cable is faulty, and you should try a different cable.

2. Check your Internet connection:
Can you access the Internet using your computer?
Connect your computer to the router, and try to access the Internet. If you can access the Internet, move on to step 4, below. If you can't access the Internet, then your broadband ISP may be experiencing network difficulties. Contact your ISP to check if there are network difficulties.
Are your username and password details correct?
Usernames and passwords are tricky things - it could be that you accidentally missed out a character, or that your case is incorrect, which would prevent you connecting. You can alter your network settings, including your username and password, using your Network Access Disc.

3. Check your router:
Is the router switched on and connected correctly?
It's obvious, we know, but it's the simplest things that sometimes trip us up. Make sure your router is plugged in and switched on, and that you have your straight through cables plugged in from it to your PlayStation®2's Network Adaptor, and to your cable or ADSL modem.
Does your router use NAT, port forwarding, or have an internal firewall?
Take a look at your router's manual; this should tell you how to use your computer to connect to your router via a web interface. Make sure that your router is correctly configured for your PlayStation®2. For more information, see our Advanced Networking FAQ in related articles.
Does your router use DHCP to set your IP address, gateway and netmask?
DHCP needs to be configured correctly, otherwise your computer, and PlayStation®2, will have problems getting an IP address, gateway and netmask. The manuals supplied with your router should explain how to configure DHCP.

4. Check your Network Adaptor settings:
Have your network configuration settings been updated?
After checking your router and ISP settings you may need to change your network configuration settings. To do this, put your SOCOM Disc back into your PlayStation®2. From here you can alter settings such as PPPoE, DHCP, IP address, gateway, netmask, and DNS servers. If you have any difficulties, see our related articles on setting up your Network Adaptor.
Are you using a manual or automatic configuration for your Network Adaptor?
If you previously configured your network settings manually, it might be a good idea to let your PlayStation®2 have another go at configuring things after fixing problems described above, instead of changing a lot of confusing settings. Put your Network Access Disc (NAD) back into your PlayStation®2. Select the Setup menu option, select your country, and then choose your broadband ISP from the list; enter in your settings and your network settings should be configured. You can save these with a different name to stop confusion.

tohru is right you need a game adapter to connect it wirelessly to the router because a usb wireless adapter will not work with it since it needs drivers installed in a system for it to work.. you can also use a wireless ethernet adapter to connect the ps2..

I go for wireless gaming adapters as I think it would be cheaper than a wireless bridge. They have the same configuration though. You may go to this link for a list of wireless gaming adapters that you may try.

There are 3 ways to connect your PlayStation 2:

1. Direct Connection
The fast and simple way to connect your PS2.

Please note, you cannot connect your PC to the Internet when using a direct connection.

2. Router Connection
Play your PS2 online and connect your PC to the Internet at the same time.

3. Internet Connection Sharing (ICS)
Connect your PS2 to the Internet through your PC. ICS is ideal for USB and PCI modems and cheaper than buying a broadband router.

Attention: Not all PS2s are ready to connect to the Internet. If you don't have the new slimline PS2, you will need to buy a PS2 Network Adapter. See your PS2’s documentation for more information.

Although PS2s have inbuilt USB ports, USB broadband modem and routers cannot be directly connected. See connection methods below for options.
