CM1000 Xfinity New Firmware now Wan Light on Modem turns amber sometimes
My CM1000 starting having Wan Light issues after recent firmware upgrade by Xfinity. The old firmware was Firmware Version
V3.01.04. Around 9 days ago Xfinity changed it to Firmware Version V3.01.0...
Its happened a few times since the firmware was updated on the CM1000 to V3.01.06. I have never encountered this before so I wasn't looking for it. I just happened to glance up at the modem and saw the light had changed from the usual green to the amber. It happened once yesterday so I checked the statistics on the XR500 Router when it was amber and it said the Wan was at 100MB. I also did a speed test that showed the limitation by getting speeds of 90MBPS compared to my usual 302MBPS. Its a quick fix to get it back to Green Wan and 1GB buy unplugging and then replugging the wan patch cable. I knew the cable was good but tried a different one just to be sure. I also called support and had them provision it to see if that helps since it has this new firmware. On the XR500 the lights are facing the wall and turned off so I don't pay much attention to those. Its the CM1000 Internet light that goes from blinking actvity green to blinking activity amber.
100 Mbps vs 1000 Mbps Negotiation is done by both parties.
You may want to do one check. Power cycle CM1000 and connect CM1000 to a Gigabit capable laptop for few hours.
If it stays green, then it is XR500 swiching mode.
If it switches Amber, then it is CM1000 switch mode
I'm just plugged in directly with my Laptop right now testing this. It just started with the CM1000 upgrade to Fimware Version V3.01.06. I never had this happen before this upgrade and its never done this with the previous V3.01.04 which is the latest version showing on Xfinity's Website. This is so new its not even listed there yet and that's why I suspect it as the reason for the issue that I've never encountered before.
3.1.06 is not fully deployed yet. It will be very soon.
how are you checking FW version on Xfinity's website? Please post a screenshot.
Please let me know what happens after you check on Laptop test.
My mistake, its actually Netgears site.
Here is a screen shot of my CM1000. I will monitor connection directly from Modem to Laptop all day tomorrow as it can take a while for this to happen.
