Upstream Light on CM2000 Blinks Constantly
Just installed new CM2000 to replace an old CM1000. The installation through Xfinity went smoothly except for the fact that the Upstream light is constantly blinking. The old CM1000 never did this. The firmware shows as V8.01.02.
Just to let everyone know Xfinity tech came to house today and determined that the outside cable (been in the ground for 18 years) was damaged and replaced the cable. This resolved the issue as internet now works properly.

Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
What is the brand and model of the host wifi router connected to the modemWiFi router is Netgear Nighthawk X6S AC4000 TriBand Router. No other changes were made. All I did was unhook the old modem and attached the coax and plugged it back in then went through the Xfinity app to setup. As an experiment I reinstalled the old CM1000 and it worked fine.
Will need to see the requested logs from the CM2000 modem being online so we can take a look to see what maybe going on there.
I also noticed that I now get a send/receive error in my Outlook email although the mail comes through and Outlook shows as being connected.
Something to contact Microsoft support about regarding there product.
