CM400 slowed from 160 mbps to 5 mbps
This randomly started happening where my internet speed has dropped from the usual expected 160 mbps down to 5 mbps. I know the issue is with the CM400 and not my router because I get those speeds even when plugged directly into the CM400.
When I reboot the modem my speeds return to normal but only for a short time (minutes) before it drops back down again.
I've attached a screen capture of the modem logs.
Does anybody have any idea what could be going on?
This happened once before maybe a year ago and it magically resolved itself after a few days (I was about to pull the trigger and buy a new modem)

A very interesting and unusual development...
I am still getting slow speeds when testing at speedtest.net but when I download a game from Steam I'm getting about 140-150 mbps. Why is that download speed fast but everything else is so slow?
Sometimes capacity testing through a web browser can yield irregular results.
Have you tried the Ookla native applications from the Windows Store or Android Play Store?
Yes. When performing the speed test via the app on my cell phone I get the same slow results as the web browser version on my PC.
