Why are you doing this when you clearly have a wireless Internet connection already, and all PS3 models, save the original 20GB, come with built-in wireless support? Unless you have one of those original 20GB models and forgot to mention it, it'd be far more efficient to just connect the PS3 directly to the wireless connection.
If you have that lone model without wireless support, then what you want is Internet Connection Sharing, not network bridging. However, unless things have improved significantly since XP, which I doubt very much given the plethora of cheap routers out there, ICS is fickle and fragile at the best of times. It will invariably stop working one day, completely out of the blue, and be nigh impossible to fix short of reinstalling Windows. You'd be far better off just getting a wireless ethernet bridge device which you can then use to add wireless support to the PS3, assuming you have the one and only PS3 model that lacks native wireless support.
I have created a network bridge connection on my laptop so I can just use a cord to connect my ps3 online. unforunatly whenever I plug the cord into the game system it can't find the ip address for the connection. can someoen tell me what's wrong with the connection that the game system can't find the ip address.
heres a run down on what I did to create the connection:
. open network connections by right clicking on your wireless icon in the tray or clicking on start then connect to then show all connections.
2. Highlight both your Ethernet and Wireless connections. Right click and choose bridge connections.
4. Open command prompt and type in "netsh bridge show adapter" with out the quotes. Find which number your wireless connection has in front of it and type "netsh bridge set adapter (what ever your number is) enable.
