Why is the Amber Col LED blinking excessively on my NETGEAR EN104TP?

If the Amber Col LED blinks excessively on your NETGEAR Switch, it could be due to a busy network or defective devices that cannot detect network traffic. Ensure connected devices are operating in half-duplex mode, as the hub isn't compatible with full-duplex. Disconnect devices one by one to find any defective units. Consider segmenting the network with a NETGEAR Ethernet switch or upgrading to Fast Ethernet. Also, incorrect or miswired cables can cause this. Verify you're using the correct UTP cables, not home telephone cables.
