WiFi 7 is officially here, but routers are pricey. Do you need it yet

Original Article ↗ Hacker News Discussion ↗

Wi‑Fi 7 routers are arriving with high prices and headline speeds up to 11 Gbps, but many users argue they see little real-world benefit when their internet connections, client devices, or building construction are the actual bottlenecks. Commenters frequently say Wi‑Fi 5 or 6 is already sufficient for typical home use, especially when supplemented with wired Ethernet, and view Wi‑Fi 7 marketing as similar to overhyped 5G or 8K TV campaigns. Others note that features like the 6 GHz band, multi-link operation, and improved spectrum efficiency could meaningfully improve performance and reliability in dense environments or for high-speed local NAS access, making Wi‑Fi 7 more about long-term “future-proofing” than immediate necessity.

Do people need Wi‑Fi 7 yet?

  • Most commenters say no for now:
    • Home ISP speeds (e.g., 300–500 Mbps, even 1 Gbps) are already well served by Wi‑Fi 5/6.
    • Few client devices support Wi‑Fi 7; routers are expensive and will get cheaper.
    • Many are happy staying on Wi‑Fi 5, 6, or even 802.11n, especially with wired backbones.
  • Some early adopters are buying Wi‑Fi 7 APs to “skip a generation” and avoid upgrading again soon, especially with multi‑gig fiber and NAS use.

Real‑world Wi‑Fi performance

  • Multiple reports that Wi‑Fi 5 rarely reaches its advertised 866 Mbps, with common real‑world numbers around 200–500 Mbps.
  • Others report ~800 Mbps or near‑gigabit speeds in optimal conditions (good routers, wide channels, strong signal, multi‑stream clients).
  • One user demonstrates ~650/470 Mbps over Wi‑Fi 5 in a local test, challenging the idea that Wi‑Fi 5 is the bottleneck.
  • Consensus: theoretical rates are optimistic; environment, client radios, and configuration dominate real performance.

What Wi‑Fi 7 actually improves

  • Multi‑Link Operation (MLO) is seen as the standout feature:
    • Can use 2.4/5/6 GHz together and switch/bond links for better reliability and “snappiness.”
    • May fix devices getting “stuck” on congested 2.4 GHz.
  • 6 GHz spectrum and 320 MHz channels offer much higher local throughput, especially for NAS workloads, but penetrate walls poorly.
  • Higher‑order modulation (4096‑QAM) yields ~20% better spectral efficiency, though some feel engineering effort would be better spent on reliability than raw peak speed.

Wired vs wireless

  • Many have moved critical devices to Ethernet; Wi‑Fi is for convenience only.
  • Some argue Wi‑Fi now exceeds 1 Gbps and that consumer Ethernet has stagnated at 1 GbE; others counter that 2.5/10 GbE exists and reliability/latency still favor wires.
  • In old or thick‑walled houses, single‑AP coverage is unrealistic; multiple wired APs or powerline backhaul are common workarounds.

Spectrum, congestion, and environment

  • Dense apartments and limited 2.4/5 GHz channels cause interference; 6 GHz is welcomed to relieve congestion.
  • Higher speeds can indirectly improve reliability by shortening airtime per transmission.
  • Very old masonry or lath‑and‑plaster houses can defeat any Wi‑Fi generation; the limitation is the building, not the standard.
