I need to open my router ports

If you connect the computer directly to the modem, does it work?
If that works then the modem is working.
Now connect the computer to the router and the modem to the router.
You will need to open the set up page of the router to check the settings of the router.
You can set up the router without the CD also.
It is very easy.

Yes you can connect wirelessly to the internet with your ps3.

Minimum Requirements

• PlayStation®3 computer entertainment system
  Note: PlayStation 3 40GB / 60GB / 80GB / 160GB models ONLY (20GB model does not have built-in Wi-Fi connectivity)
  
• SIXAXIS™ wireless controller (and USB cable)
• AC power cord
• A high-speed Internet account (cable or DSL) with an Internet Service Provider (ISP)
• Router
  
  
  • Wireless router compatible with 802.11b or 802.11g Wi-Fi standards
  • Or an Ethernet (wired) router with a Wireless Access Point (WAP)
    You may need to open firewall port numberson your router to connect to the Internet.
    The PlayStation 3 will not connect to the Internet through the USB ports.
    
  //
• Updated system software installed on your PlayStation 3
  Visit PlayStation 3 System Software Update to download and install the most recent version.
• Your Wireless Network Settings
  
  
  • SSID
    You will need to know the Service Set Identifier (SSID) of your wireless network. Also make sure the WAP or wireless router is set to broadcast the SSID; otherwise, the SSID will NOT appear on the PlayStation 3 scan results.
    If you do not know this information, speak to the person who configured your home network (i.e., wireless router) settings.
    
  • WEP or WPA Security Key
    If your wireless network access is security-enabled (encrypted) from open access, you will need to know your WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) security key or password
    If you do not know this information, speak to the person who configured your home network settings.
  • MAC address
    You may need to enter the Media Access Control address (MAC address) of your PlayStation 3 into your WAP if it is required by your network settings.
    

Playing Online Games Behind The Router

A router uses a combination of hardware and software to prevent unauthorized users or internet traffic from accessing your private local area network (LAN). If your game console, such as Playstation is behind the router, you will need to configure routers Port Forwarding feature in order to play online games.

Note: You will need to get the ports and service type for your games. This is usually available from the games website.

Steps how to configure router to play online games:

1. Open a browser and type in the following URL: http://www.routerlogin.com or http://192.168.1.1 (depending on the model number of the router)
2. Type the Username as admin and the Password as password and click OK.
3. Click on Port Forwarding under Advanced menu.
4. Then click on Add Custom Service

5. Under Service Name, type the name of the game.

Select the Service Type from the drop down menu (depending on the game).

Type the Starting Port and Ending Port numbers (depending on the game).

Type the IP address of your PlayStation in the Server IP Address box and click Apply.

Click on WAN Setup under ADVANCED menu.

• Check the Disable SPI firewall box
• Change MTU size from 1500 (which is the default) to 1300 and click Apply.

Now the Playstation is ready to use.

I hope this helps...

so your trying to use a dsl router as just a router -dsl with dialup?

you need to change the IP address of the router. Plug just the router into the computer. Open Internet Explorer and go to 192.168.1.1. user: admin password:password. On the main page it allows you to change the LAN IP. Make it 192.168.2.1. Now unplug everything and rewire it correctly. This should fix the issue. Verizon uses 192.168.1.1 for the modem well so does Netgear and this causes the network to not function. So changing the IP of the router should fix this issue and has worked for me many times that I have done that set up.

Actually you need to open the port on the cable modem / router. Switches just pass the packets along.

with the router connected, open Internet Explorer and type http://192.168.1.1 after you log in there is a option on the left for firewall and you can turn it off. If it were me I would use the routers firewall over a software firewall though. By the time a software firewall detects a hack, its already in the PC.

Make sure your Netgear router is working correctly and is allowing the PS3 access to it. I suggest visiting the Netgear website (www.netgear.com) and searching for the Router you have. Also try taking down any firewalls that are set up on your computer this will allow the PS3 unlimited access to the connection.

The question is how do you want to cable the netgear and what do you want to do with it.

If you cable a lan port of the DLink to the Netgear WAN port you will have two subnets that must be addressed differently. Opening up and forwarding the ports for XBox could be difficult.

I believe cabling the Netgear as an access point makes more sense. CONFIGURE THE NETGEAR BEFORE CABLING. This is achieved by wiring a lan port on the DLINK to a lan port on the netgear and ignoring the wan port on the netgear. This will involve configuring several router items that should be completed before the devices are cabled together. You will need to remember the Netgear's new network address and probably use a static IP address from a computer to configure it back into being a router after these changes, if required. Or reset the configuration to factory default following the users guide.

First the Netgear needs DHCP turned off as it will be part of the DLink's network and not a separate subnet - the DLink will perform the DHCP services.

Second the LAN side of the Netgear will need a static IP address in the DLink's network. This is where it may get tricky for you. Verify the DLink has an IP Address like 192.168.0.1 and a subnet mask like 255.255.255.0. That means all IP Addresses in your network start 192.168.0.??? where ??? is unique for your network. Verify your DLink router has a set of addresses reserved in the DHCP setup for dynamic address assignment these addresses like 192.168.0.100 to 192.168.0.199. If the above is true or with the information you extract from you DLink router you need to determine where you can create static IP addresses -- in the above case 192.168.0.2 to 192.168.0.99 are available. You need to assign one of those like 192.168.0.2 to the LAN side of the NetGear Router. You will probably want to assign another to the XBox == like 192.168.0.20. You will probably need to deal with opening ports or placing the XBox into the DMZ of the DLINK router which will require a static IP Address.

Now cable the devices

When considering the XBox Configuration below the DLink is the router that must be configured to allow the open ports or DMZ access to the Xbox == the netgear is not functioning as a router in this configuration.


Check out the following links on XBox Configuration if required.

The second link may be the best to start with.

This is a good description of possible router options.
