super slow internt speed / modem has DS blinking light
I have the 1 Gigabit plan, and my speed was great but recently in the past couple days I notice that my speed was super slow and when I do speed test, I get as low as 6 Mbps and up to 140 Mbps through out the day. both via wifi and Ethernet connection to my PC.
I also notice that my modem has the downstream light blinking, used to be solid all the time. but now is just blinking.
I only have internet service nothing else. modem is connected straight to cable that comes outside. so no splitter.
my modem is a Netgear CM700, here is a photo my downstream channel info.

Get a tech out to investigate. Your modem is only locking in 24 of a potential 32 downstream channels. And many of them have SNR values that are too low / out of spec. And there are many uncorrected bit errors. Noise ingress causes these symptoms. There is noise leaking into the line(s) somewhere. Good luck !

It's a line / signal impairment. Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it up to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.
Good luck !

99% it's not the modem.
