- Stable connection for everyday use.
✖ Cons:
- Not future-proof (no Wi-Fi 6 or DOCSIS 3.1).
- No advanced security features.
- MU-MIMO missing for multi-device efficiency.
Alternatives:
- Motorola MB8611 + TP-Link Archer AX50 (~$300) – Better for gigabit speeds & Wi-Fi 6.
- ARRIS Surfboard SB8200 + ASUS RT-AX86U (~$400) – Premium DOCSIS 3.1 + gaming router.
- Netgear Nighthawk CAX80 ($399) – DOCSIS 3.1 + Wi-Fi 6 in one device.
Bottom Line: If you’re on a cable plan ≤ 600 Mbps and want to stop renting equipment, the Nighthawk AC1900 is a smart buy. For faster speeds or future-proofing, consider DOCSIS 3.1 + Wi-Fi 6 setups.
