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

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.

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

IF the ISP sets the modem correctly and it doesn't work, modem could be faulty. Hopefully the ISP can help check all this.
