CM500 Slow Download Speeds and Download light blinking green
Firmware Version V1.01.05 For the last few days, download speeds have been painfully slow and only the download light is steadily blinking green. All other lights are solid as they should be. ...
My CM500 has recently started the same thing(upstream light blinking). Connectivity/speeds don't SEEM to be affected, and a reboot always temporarily stops it.
Hello rightintel
I would contact your ISP have them check the levels and connection of the modem also if you have any cable splitters on your cable line try to remove them and connect directly to the wall.

No splitters, connections are tight.
Here's the modem log:
