Ethernet port lights turn amber


Ethernet port lights turn amber


For some reason white lights on ethernet ports (ports that connect to PCs) on my router turn amber.  I have  to unplug ethernet cables and reconnect then  lights turn white again. A day later back to amber. So instead of 1 Gbit speeds I get only 100 Mbit.  So my download speeds go from 200Mb  to 90Mb.  Anyway to prevent the router ethernent ports turning amber.  Thanks

First thing I'd do is replace with proper cables (which do go bad from time to time). Get minimim CAT5e, preferrably CAT6. If that doesn't work, do a factory reset and configure manually

I would also check the other end of these Ethernet links, the PC bit.


Maybe a Windows setting is sending the LAN to sleep or something like that.

Thanks.  These are cat7.  I think there is a problem with netgear and cat7 cables.  Not sure why

Would not think cat7 cable would be a problem. Can find out real quick by trying a  cat5e or cat6 cable and see it problem goes way with that PC. Major differences are how tight the twists are in the cable and shield on end. Pin layout is same.

Since when the connection is reistablished, you are running at 100 mbps rather then gig, that would say the connection is good, but for some reason the Ethernet connection is not negotiating properly. I would check and make sure the Network adapters in the PC's are set to Auto Negotiate. Have seen folks try to get clever and set their NIC to the speed they want rather then auto and then have connection issues as the far end is still trying to negotiate and the other end is not talking to it.
