I recently purchased a PS3. I use it only for one person games and do not do any online gaming so I never bothered hooking it up to the internet. Then one of my friends told me you can do a lot more than that on it and showed me how to connect it to the wireless router. All good.
One day my son comes over and he wants to play DC Universe online. I didn't want that happening over the wireless (too many devices in this house) so I moved the Ethernet cord from my PC to the PS3 and changed the settings. The PC is also wireless so he was able to play and I was able to browse. Again all good.
After he left I moved the wire from the PS3 back to the PC but when I went to change the settings on the PS3 back to wireless it won't go. It simply will not connect to the router. Does anyone know if there is anything special I have to do to get this to work again?
