Spectrum Gig Internet Problem with CM1200
So, since September 8th, 2020, I've had nothing but problems with my internet. At the time it began, I had 400Mbps service, and was using my CM600 modem, and an Asus RT-AC3200 router. At the point tha...
Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
The dummies at Spectrum are lazy. Over the years, even prior to my ownership, there's been time Warner, directv, dish, etc. My drop ceiling looks like spaghetti. They will not remove all the lines and start 100% fresh, without charge, and I honestly don't trust them anymore. I'd rather pay a local home theater, A/V contractor to re-run everything after it enters the house. Spectrum also always takes the easy way out. They said, "it's common practice to run one line to the TV closest to the modem, and split it for connecting the modem" (because drilling one more hole and running another 20 feet of line is soooooo time consuming... The drop is replaced. They did say somewhere there were plate/plant issues, but only God knows when the F anything will be done on that. So, basically the line comes into the house, gets amped to a 4-way, with a -10db filter, up to the living room, where a -3db splitter goes to the cable box and modem. They have no idea what they are doing. As long as their stupid meter shows "all green", they DGAF. I'm no tech, but it seems to me, there should be a 2-way line split at entry; one only to the modem, with full signal pass through (maybe even amped), then the other side to everything else. I don't think boxes require much, especially since the pole/plate are less than 90 feet away.
Again, hook up directly where the line comes in. put a splitter prior to the 4 way and amp and run the 1 leg to the modem. If everything looks good and works, then it is indeed the wiring in the home.
Amps in my experience only create issues when they're inline with the modem. If the signal isn't good enough to the point they need an amp prior to the mode, then the signal they're amplify tends to be bad.
- I don't honestly know where the line comes in at this point. In my drop ceiling, there's old black coax, both thicker and thinner, white coax, and then new-er black coax. I have no way to know what goes to what/where, unless someone pulls all of it out and starts over.
they make some pretty cheap coax tracers.

easy way to see where each cable goes and label them
