Frequently Asked Questions
In most cases, the DOCSIS 3.0 standard works fine. However, in case network congestion is commonplace in a particular area, DOCSIS 3.1 support helps increase the WiFi channel width and provides more speeds.
A combination of a modem and WiFi router is convenient but a separate modem and router offer better performance, stability, and flexibility. I'd personally go with separate devices.
IPv6 auto-configuration, allows you to set up the device easily. Plus, you get hold of the truest possible QoS functionality, which makes way for flow labeling and better network traffic prioritization.
Verdict
I hope the article was helpful in making an informed buying decision. Regardless of the device you like, the final decision eventually boils down to the subscribed service plan and the money you spend.
If you're still confused and unable to make a call, here are my final suggestions:
- Motorola MB8611 is the best option for higher speeds, lower latency, and top-tier performance.
- If you are only looking for a reliable modem router compatible with Cox, check out the Netgear CAX30S.
- If you're on a tight budget and need a reliable device, nothing beats the Hitron CODA.
