Okay. My laptop is connected over wifi to my router. Then i plugged a ethernet cable from my laptop to my ps3. In debug settings I selected:
Release Check Mode: Development Mode
Boot Mode: System Software Mode
Network Settings for Debug: Single Settings.
Then I went to the target manager and searched for the PS3. I couldn't find it. Same on Dual Settings.
But I realized that, when I set up network bridge, that the wifi can't connect. How to fix that?

remove both from bridge, right click wifi go to properties and make sure you have sharing set up correctly.

also be sure to redo the network settings and test on your ps3

What are the correct settings?
btw: I'm on XP Pro

well, once you have internet sharing enable correctly, and you go to your internet connection settings on the ps3 you want to choose custom/wired/auto/auto/do not set/auto/auto/do not use/enable/ then hit X and test connection.

make sure you check your IP before you try to connect with target manager. after enabling internet sharing your ip will change.
