Buying Guide

DOCSIS version matters

Choose a modem with the DOCSIS version your ISP supports—many reliable budget units use DOCSIS 3.0 with 16x4 channel bonding for common cable plans

Check channel bonding (downstream x upstream)

Higher downstream/upstream channel counts (e.g., 16x4) improve throughput and stability on shared cable networks, important for streaming and gaming

Look for a gigabit Ethernet port

A single Gigabit Ethernet port ensures you can reach multi-hundred Mbps plans when paired with a capable router or gateway

Consider modem-router combos vs standalone modems

Combo units include Wi‑Fi but may offer lower wireless features than a dedicated router; standalone modems pair with separate routers for more flexibility

Confirm ISP compatibility

Verify the modem model is supported by your cable provider (commonly listed for major ISPs) to avoid provisioning issues
