Question Need advice on which DOCSIS 3.1 cable modem

[mscifiwriter]

Hey everyone,

I apologize in advance for being a little to wordy here, I'm just trying to provide the best information possible to get the best feedback possible. And I really could use feedback on which DOCSIS 3.1 cable modem to get. As I've been trying to figure this out for a week. Also a quick side note, I've verified with my ISP that they support the cable modems I'm considering. Does anyone here have experience whether good or bad, with the Arris SB8200 or Netgear Nighthawk CM1200 cable model? Or if there's a different cable modem you'd suggest?

Also something I'm trying to understand, my ISP said to make certain the modem I choose is able to support 16 or more downstream channels. which itself is clear cut. But when I looked at the Arris product page it gets confusing, as for the downstream for the SB8200 it says:

"32 downstream DOCSIS 3.0 bonded channels, OR 2 downstream OFDM DOCSIS 3.1 channels"

So does that mean for the DOCSIS 3.1 protocol there are in fact only 2 downstream channel?

Where as the Netgear product page for its Nighthawk CM1200 cable modem, it says:

DOCSIS 3.1 Cable Modem Up to 10X faster download speeds than the DOCSIS 3.0 standard. Fully backwards compatible with previous DOCSIS standards. Supports 32 downstream and 8 upstream channels.

So does that mean the Netgear is indeed better on the DOCSIS 3.1 protocol, or is the Arris information just worded more confusingly?

Most people didn't know about the issue, including ISPs or at least their ground level techs until late 2017/18. Its been slow going getting the word out. Intel denied the problems for a year along with the normal blame game. Some modems/ISPs got firmware fixes that mitigated some of the problems.

The problem is that I could not confirm a single thing alleged about these issues. Even when comparing side-by-side with other modems including the isp ones. None. Zero. Nada. And both modems even passed the dslreports test that was supposed to reveal any issues with a modem.

Now, I think you are really dead-on about the fixes, which when an isp pushes their firmware and exact config to a user modem, would have provided a workaround/fix to any issues--hence most people wouldn't even see any problems--like I did.
