What does an amber, rather than usual white, light indicate on one of the device lights?

I currently have two computers connected to the routeer.  The indicator lights have always shown white for the respective two connections.  Now one is showing amber??

Amber means it's running at 100 Mbps instead of 1 Gbps. I'd try a new cable if you're sure your PC is capable of 1 Gbps speed

I followed the sleeping computer suggestion and "woke up" the one sleeping computer - router light still amber??

You didn't mention you had a "sleeping PC". If a PC sleeps and WoL (Wake on LAN) is enabled, it runs at 10 Mbps and the router reflects this. If the PC is then fully booted and the router still shows amber light, either it's negotiating at 100 Mbps or you may need to try a different cable for 1 Gbps white light

Well .. The simple "wake up" didn't solve the issue, but a reboot did.  As the computer came back up, the router saw it and displayed a white indicator light.  At least in this instance, question solved.

Thanks for all who offered suggestions.
