[Playstation 3] Unable to connect: DNS Error
How to restore a connection problem for your PS3
In most cases, simply go to the Settings Network Settings/Test internet connection.
Testing your connection (if it is fully configured in advance) can eliminate this problem.
If this does not work, review the configuration of your network (ps3, router, etc ...), make sure that everything is connected correctly and do not hesitate to ask your questions in the appropriate
forum.
