Do you actually need a mesh WiFi system? (Usually, no)

The short answer: probably not

Mesh WiFi is sold as something every modern home needs. It usually isn't. For most houses a single decent router already covers the place — and a mesh system is more boxes, more wall-wart power, more firmware to keep updated, and more to go wrong.

What the evidence says

Wirecutter tested a single router against an expensive mesh kit in a 2,300 square-foot home and found the single router performed as well. That is the result most people will see: one good router, centrally placed, covers a typical home.

When mesh IS worth it

• Thick walls, long ranges, or multi-floor layouts where one router genuinely cannot reach.
• You have confirmed the gap — by testing, not by assuming — and a higher-gain router or a powerline backhaul will not do.
• You want seamless handoff as you walk around (genuinely nice, rarely essential).

When it is just more stuff

• Your home is small or medium and the current router is just old or badly placed. Move it. Buy one better router. Done.
• You were told you "need" mesh by someone selling mesh. Test first.
• You are chasing speed you will never use — most UK lines are the bottleneck, not the WiFi.

The minimalist call

Buy one good router. If, and only if, you measure a dead spot, add a single mesh node or a wired access point. Resist the three-pack by default — it is usually solving a problem you do not have.
