Arris S33 vs Netgear CM2000 Reddit Answers

1. I recently acquired an S33. I’m not aware of any problems with it. Like the CM2000, it makes use of the BCM3390 chipset from Broadcom. I’m not sure if my router or modem truly need cooling because they are both set to run cooling fans by default. There isn’t likely to be any noticeable difference in actual performance between the devices; instead, I believe the router will have the most influence on network performance.

2. I really want to get things right since the modem makes up half of the home’s internet-providing hardware, which means that if the modem malfunctions, the router will too (whereas the modem will still function if the router malfunctions). I’m leaning toward the CM2000 as a modem that can fully unleash the full power of my ASUS ROG-Rapture GT-AX6000, but $300 is pricey (I can’t swear in this community).


3. First off, your worries are unfounded, according to my experience with the S33. By default, the S33 will supply the main service on the 2.5 GB port. You must contact Comcast to get the second port supplied with a second IP or service in order to use it, even if the 1.2 Gbps plan eliminates the requirement for this. If the 2.5 Gbps port is used for the main service, it will only function as a “true modem”.
