Start with client support
Wi-Fi 7 benefits are strongest when laptops, phones, or adapters can actually use the newer standard. Older devices can connect, but they do not magically become Wi-Fi 7 clients.
Check wired ports
A Wi-Fi 7 router with gigabit-only paths may still bottleneck a multi-gig internet plan. Look at WAN, LAN, switches, and backhaul together.
Coverage still beats speed class
A poorly placed Wi-Fi 7 router can perform worse than a well-placed Wi-Fi 6 mesh system. Layout comes first.
Buy for the next bottleneck
Upgrade when the current problem is coverage, device density, or wired speed. Skip it if the main problem is a bad router location.
