WIRED NETWORK ERRORS
This is usually the result of a lost connection to the home network and can often be corrected by performing a few troubleshooting steps.
Note: If this is your first time connecting to your wired network, see Wired Network Setup.
Check the connection
Verify that the LAN cable is routed properly. A LAN cable is required from the modem to the router in order for the router to receive a network signal.
Access the Network or Connection Status screen in the setup menu of the device and run a status test. If the Wired Network Settings have not yet been configured, this option may be grayed out. See Wired Network Setup.
Is the Network/Connection Status Test successful?
