Possible Solution
Check the power cable connections at the
router and the power source.
Make sure that all cables are used correctly
and comply with the Ethernet specifications.
Check the crimp on the connectors and make
sure that the plug is properly inserted and
locked into the port at both the router and
the connecting device.
Make sure that all cables are used correctly
and comply with the Ethernet specifications.
Check for a defective port, cable, or module
by testing them in an alternate environment
where all products are functioning.
Break the loop by making sure that only one
path exists from any networked device to any
other networked device.
Verify that the cabling is correct.
Make sure that all connectors are securely
positioned in the required ports. It is possible
that equipment was accidentally
disconnected.
Break the loop by making sure that only one
path exists from any networked device to any
