Factors to Consider
Compatibility is limited to major cable providers like Comcast Xfinity, Time Warner Cable, Charter, Cox, and Cablevision, but is not compatible with Verizon, AT&T, or CenturyLink, requiring verification with your ISP before purchase.
The modem supports internet plans capped at 100 Mbps but can handle higher technical download speeds up to 343 Mbps and upload speeds up to 131 Mbps due to DOCSIS 3.0 technology, which gives headroom for stable performance in typical home use.
This device integrates both a DOCSIS 3.0 cable modem and an N300 dual-band Wi-Fi router (2.4GHz + 5GHz) in one package, simplifying setup and reducing clutter, but the router uses 802.11n Wi-Fi standard rather than newer Wi-Fi 5 or Wi-Fi 6 protocols.
The router portion includes a 4-port Gigabit Ethernet switch allowing multiple wired device connections, ensuring reliable and fast local network connections where Wi-Fi may be limited.
While supporting both IPv4 and IPv6 internet protocols enhances forward compatibility and security, the retail packaging and device aesthetics are simple and functional without premium design features.
At its price point, this ARRIS device offers strong value by combining a cable modem and dual-band router into one reliable unit, ideal for users with cable plans up to 100 Mbps who want to avoid separate device setups.
With DOCSIS 3.0 technology, 8x faster than older standards, dual-band Wi-Fi N300, and gigabit Ethernet ports, it delivers solid performance that meets everyday internet and networking needs efficiently.
Customers benefit from a straightforward all-in-one setup, stable internet connectivity, and adequate wireless coverage, making the device easy to use and dependable for typical household internet requirements.
