Unable to connect to the Internet or a network, or the connection is slow

The Windows Vista operating system has the ability to use the new Internet Protocol Version 6 (IPv6). Most routers purchased before December 2006, however, are not capable of using IPv6. It may be necessary to disable IPv6 in order to establish wireless or wired communication with your router or Ethernet Local Area Network (LAN). Follow this procedure to disable IPv6.

NOTE: If any changes to this resolution become available, this solution will be updated and the information will also be posted to the Sony Support Web Site.
