How to resolve when "Connection status cannot be confirmed" message is displayed during the network upgrade?

Connection status cannot be confirmed message is displayed during the network upgrade.

There may be a problem with the network connection. Verify the network connection and settings if correct.

1. Check the Ethernet cable to make sure it is securely connected to the LAN (100) terminal on the unit and to the Internet source.
2. Check the Blu-ray Disc/DVD Home Theatre System network settings and confirm that the system has its own IP address.
   
   Note: If you use a proxy server, enter the IP address of the proxy server you use, instead of the proxy host name, in the Proxy Server input field.
   
3. Follow the Network Upgrade Instructions again.
