2.5G WAN port: Choose a router with at least one 2.5GbE WAN port so a 1.5Gbps, 2Gbps, or faster internet plan is not bottlenecked at the modem connection.
10GbE WAN port: For 5Gbps or 10Gbps fiber, prioritize a 10GbE WAN port or SFP+ port; it provides necessary headroom beyond 2.5GbE.
2.5G LAN ports: Count wired devices before buying: gaming PCs, NAS drives, consoles, and switches benefit from dedicated 2.5GbE LAN ports.
10GbE LAN ports: A 10GbE LAN port is valuable for NAS transfers, high-speed workstations, or connecting a multi-gig switch; it is less essential for ordinary devices.
Wi-Fi 7 support:Wi-Fi 7 is worthwhile for multi-gig plans, many modern devices, and lower-latency Multi-Link Operation, especially when using the 6GHz band.
Tri-band design: Prefer tri-band Wi-Fi 7 with 2.4GHz, 5GHz, and 6GHz radios; it helps separate older devices from high-speed 6GHz traffic.
Wireless speed ratings:Treat advertised speeds as lab maximums, not guaranteed real-world rates; check independent tests and focus on consistent throughput at your usual distance.
Coverage and mesh: Large homes or rooms with thick walls may need a mesh system or wired access points; a powerful standalone router cannot fix every dead zone.
Processor and memory: A strong CPU, ample RAM, and quality QoS help maintain performance when many devices stream, game, download, or use smart-home services simultaneously.
