Slow download speed/Amber modem light

Xfinity performed network maintenance in my area a week ago. Immediately after the maintenance ended and ever since my modem will not connect to the 1000mbps network and instead of the green light on the modem I now am getting the amber light meaning the modem is connecting to the 100mbps network. I subscribe to the 100mbps plan and was receiving around 110mpbs provisioned speed before the maintenance and now I'm receiving around 93mbps. I also tried removing my router and still am receiving the slower speeds. As I said this all started the same day as the network maintained in my area.

Which light. Not sure what you mean by the "100 or 1000 network" ? The color of the light typically means whether or not the modem is locked on to multiple bonded channels. What you posted shows that it is and everything is normal / in spec.

The light used to be green. This is what my cable modem documentation says.

This notice in the modem event log appears ever since my slower speeds began.

O/k that's an ethernet port / LAN light. It's on your network / LAN and has nothing to do with the Comcast connection / system. 

 

So what ever device it is that you have connected to that port is not negotiating a gigabit connection. Does the device have a 10/100/1000 gigabit capable NIC / network adapter ? Check the integrity of the ethernet cable as well.

I tried connecting the modem directly to my other devices and still I was getting the amber light. I tried different CAT 6 ethernet cables. I'm able to get a green light for a few minutes and run speed tests and I get the proper speeds and then it goes back to amber on the modem. Now at 4am I'm not having any issue at all with my light being amber.....it is staying solid green. This sounds like an Xfinity issue, doesn't it? I'm wondering if Xfinity is slowing me down at certain times of the day. This issue only began 9 days ago. Am I being throttled? As I said all is remaining green and faster speedtests at 4am.

FWIW, they can not change the port negotiation speed / color of that light on your LAN / computer remotely. Something else is going on. Perhaps that port / gateway device is malfunctioning. Have you tried another port on the gateway ? No joy ? Get it swapped out for another. There could also be something intermittent going on with your computer's NIC / network adapter / ethernet port.

 

Good luck with it !

I have a theory right now. This seems to happen when I have my stereo turned on at the same time and the speaker wires are close to the ethernet cable. I believe my ethernet cable is the UNshielded type. I turned the stereo off and the amber modem light turned green when I unplugged it and plugged back in! Do I simply need to purchase a shielded ethernet cable? I'm thinking there's interference from the speaker wire when I occasionally have my stereo on when the TV is also turned on and I'm streaming through the internet to the TV.
