Ethernet light on modem flashing amber

Hey all,

 

My ethernet light on the CM1000 modem started blinking amber overnight. It's been a solid green ever since I bought it a few months ago. My router (TP-LINK Archer C7 V2) has been at the latest firmware. Internet and wireless works. It is a little slower; I'm supposed to get 500 mbps but am getting around 100 wireless. I usually get around 300. 

 

I've read the manual and it says that a blinking amber light means processing traffic, but it's always been solid green before. Anyone know what I can do, if anything? I've unplugged and replugged the router. I've also restated the router and modem to no avail. 

 

Thanks!

    you're getting 100mbps (max) and not gigabit for the connection/link speed (actual throughput will always be less). For Netgear, orange means 10/100mbps, and white means 1gbps. I had a similar problem and it turned out to be the Ethernet cable. You've already done most of the troubleshooting, so I just wanted to add extra confirmation for you that it is in fact the Linksys router you've plugged into it.

    to add to that, it might be the router, it might be the modem, it might be the cable. 

    Start with the replacing the cable.

    Then you'd want to try plugging a pc/device that is gigabit directly into the modem to see if it is indeed on the modem or router side that's causing issues.
