CM700 flashing Ethernet light

I’m having issues with my cm700 and connections to my ISP. My isp (mediacom) says they can see that the line is live to the house. Here’s where it gets odd. I unplug the co-ax and connect to the modems web gui after a reboot and it stays stable until I reboot it again (10min tested stable). I plug the coax back in (after I had already unplugged it), plugged power back in, plugged the Ethernet in and I can get maybe 15 pings on it, and can get to the web gui for maybe 10seconds. Then after that 10seconds, bam, the ping dies, I can’t get in the gui anymore, my computer says it’s connected but the Ethernet light starts flashing green at a consistent speed. I unplug the co-ax and then it starts back up on the ping, I can get into the gui, and the Ethernet light is solid green.
  • the ISP did not provision the modem correctly 😐
