How To Connect PS3 or Xbox Via A Laptop (Bridge Connection) To Access The Internet

You need a Crossover Ethernet Cable to perform this task because you are connecting two NICs together directly rather than through a switch/hub or router. Essentially there are three ways to connect this, but two of them I will combine into the first one:

1) Connect PS3 -> Switch/Hub/Router -> Laptop -> Internet
What you would need is two RJ-45 Ethernet cables and either a switch, hub or router. You'll then have to setup the switch, hub or router so that the PS3 and laptop can see each other in that network. Once you can see the PS3 from your laptop in Network Neighbourhood (I believe that's where all your networks appear in Windows) then you can right click on one of the connections and select Bridge to bridge the connection between that and the network to the Internet.

2) Connect PS3 -> Laptop -> Internet
For this setup all you need is a Crossover Ethernet Cable. Connect one end to the PS3's ethernet port and the other to your laptop's. Then in your laptop, you'll have to configure the laptop's NIC TCP/IPv4 settings to have a static IP address. Set your laptop's setting as so:

Laptop IP Address: 192.168.3.1
Laptop Subnet Mask: 255.255.255.0
Laptop DNS: 0.0.0.0 (I don't think this matters, leave it blank if you can)
Laptop Default Gateway: 192.168.3.2

Now on your PS3 you have to set the IP Address to static too and set it up as follows:

PS3 IP Address: 192.168.3.2
PS3 Subnet Mask: 255.255.255.0
PS3 Default Gateway: 192.168.3.1

After you made those changes and save them, you'll need to disconnect, wait a few seconds then reconnect the crossover cable. Now when you go to Network Neighbourhood (Again I think this is where you see your networks in Windows) on your laptop and you should see two networks. One is the network that you were connected to before for the Internet and the other is the one you just created to the PS3. Just highlight both networks, right click and there should be an option to Bridge Connections. After that you can run the Test Connection check on the PS3 and it should be able to find the Internet.
