Overview
A cable internet home with streaming, gaming and a few wired devices is where this ARRIS unit fits, combining a cable modem and dual-band router in one box. Setup runs through the SURFboard Central app, which also handles parental controls and device monitoring.
Two devices in one shell means fewer cables and one app for the whole network. Compatibility is the limit: cable providers only, and anyone with a phone line through the cable company needs a voice capable modem.
Who it's for
Cable internet households on plans within its rated speed get a single box with app setup and parental controls. Homes on fiber or DSL, or those using cable digital voice, should look elsewhere.
Pros and cons
- Modem and router in one box
- Four gigabit Ethernet ports
- App setup and monitoring
- Parental controls with time limits
- Cable internet only
- No cable voice support
- Needs ISP approval and activation
- Listing bullet contradicts its own Wi-Fi
Performance notes
Download speed is capped by the DOCSIS standard and your plan, while Wi-Fi reach depends on placement in the home. Dual-band radios split devices between bands to spread load. The app shows connected devices in real time for troubleshooting.
