The connection is still established, and data packets are being transmitted or received at a lower speed than possible.įor example, if you have a Ethernet card with gigabit support installed on your computer but the router only supports 100Mbps, the LED light will be yellow instead of green. This color appears on the ethernet port to indicate a slower speed connection. The specific rates might differ from brand to brand but are generally in the 10/100Mbps range for fast Ethernet or 100Mbps for Gigabit Ethernet. It indicates that the connection is good and data packets are being transmitted or received at an average speed. Green is practically the most common color on the ethernet port.
