CM600 and Suddenlink
I recently upgraded from an Arris SB6190 afte learning about the puma 6 issues while dealing with some inconsistent connectivity with my cable internet. Those connectivity issues resolved themselves ...
turns out the initial Suddenlink rep did not properly provision the CM600 with the 400mbps speed under my plan.
I am getting 400mbps now. Thanks for your help guys! I've learned a lot
You're power levels are low. The ideal range is -7dbmv to 7dbmv. Minimum acceptable ranges are -8/10 dbmv to +8/10 dbmv. some devices will work up to -15dbmv to +dbmv but can have issues/drops.
I'd try pulling that 4x splitter out of the line.
If you have to split, you should do a dual splitter with one line going to the modem and the other going to another splitter if needed for tv's. That way the modem is still getting the signal with only a slight reduction.
Also check for extended runs, kinked coax, loose connections, etc. this can cause issues to.
if you continue to have issues, have suddenlink check your line as your power levels are to low.
many people use the CM600 with my ISP=suddenlink with no issues whatsoever. In fact, it seems to be the most frequently recommended one. No one has confirmed reliable use with a CM1000 or greater.
I plugged the modem directly into the drop at the demarc today. This helped the signal levels tremendously. Will be switching the current four way to a two-way into a three-way . BUT this did not help the speeds. If anything, I was getting less than the typical 20mbps i had been getting at the end of the modem's RG6 run.
I'm thinking this confirms that either this particular modem is faulty or my ISP has not properly configured my modem. Will be giving them a call later today. If that does not solve anything, I will be getting a replacement CM600 and CM500 and trying those.Below are the signal levels of the CM600 plugged directly into the drop

Here are the signal levels of the Arris SB6190, plugged in where the modem normally lives in the house.https://i.imgur.com/i5JlwEw.png

Here is the speedtest of the Arris at its normal location, getting exactly 400mbps

Like FURRYe38 said, I'd check with the ISP on provisioning.
Its also a bit of going from a 32x8 (arris) modem to a 24x8 (netgear) modem.
that being said, you should hit faster than you are on the CM600.
You said the connectivity issues with the arris had fixed themselves? As much as I like netgear products, arris makes a pretty decent modem.
since you've got both devices, you could test them using dslreports modem testing. It works pretty well for showing issues. They have a specific puma6 test to check devices and see if firmware fixes helped.

The DSL report test confirms this SB6190 has the puma 6 latency issue. we've been having the intermittent connectivity issue with it since we got it. But 400mbps with periodic connectivity issues is almost better than 20mbps.
What specifically should I be asking suddenlink when I get them on the phone? I want to be as clear with them as possible, since a lot of their phone support staff seem to be not the most proficient at their jobs.
We also have a bear fence, whose wire I just noticed is run parallel to the coaxial cable. Turning the bear fence off increases the signal level by about .1 dB so it doesn't appear like it's a major issue, but I will also re-run the coax cable at least 12 inches away from that wire just to be safe. The coax cable is quad shielded but better safe than sorry.
