Routers

Compare support for the devices you already own, not only the latest Wi-Fi name. Higher-frequency bands can offer useful capacity under suitable conditions but are not a universal coverage improvement. Walls and interference change results. Place the router where it can serve your rooms rather than hiding it behind large furniture.

Check WAN and LAN port speeds, how many wired devices can connect, and whether a port changes role in a particular mode. Mesh expansion usually needs explicitly compatible hardware. For a larger home, wired backhaul can be worth more than a higher headline wireless total. Confirm Ethernet cabling and supported operating modes.

Look for security updates, a usable administration interface and clear guest-network controls. Establish which features require an account or paid service and what remains available without them. Save setup details and review default credentials. A device with limited future support can be a poor long-term purchase despite a low initial price.
