What Is Wi-Fi 6?

Wi-Fi 6, officially known as 802.11ax, is the sixth generation of Wi-Fi technology. Released to consumers around 2019 and now widely available, it represents a significant leap forward — not just in raw speed, but in how efficiently it handles multiple devices at once.

If your home has a dozen or more connected devices — phones, laptops, smart TVs, tablets, smart speakers — Wi-Fi 6 was designed with you in mind.

Key Improvements Over Wi-Fi 5

  • Higher theoretical throughput: Wi-Fi 6 can reach peak speeds of up to 9.6 Gbps, compared to around 3.5 Gbps for Wi-Fi 5. In practice, real-world speeds depend on your ISP plan and device capabilities.
  • OFDMA (Orthogonal Frequency Division Multiple Access): This technology lets a single router communicate with multiple devices simultaneously rather than one at a time — reducing lag and improving efficiency in busy households.
  • MU-MIMO improvements: Wi-Fi 6 upgrades MU-MIMO to support up to 8 simultaneous device streams, up from 4 in Wi-Fi 5.
  • Target Wake Time (TWT): Devices can schedule when to wake up and communicate with the router, preserving battery life on smartphones and IoT gadgets.
  • Better performance in dense environments: BSS Coloring helps reduce interference from neighboring networks — a genuine benefit in apartments and dense neighborhoods.

Wi-Fi 6 vs. Wi-Fi 6E: What's the Difference?

Wi-Fi 6E extends the same standard into the 6 GHz band, which is a brand-new, less congested slice of spectrum. It offers lower latency and faster speeds but with reduced range. If you're buying a router today, Wi-Fi 6E is worth considering if your devices support it.

Feature Wi-Fi 5 Wi-Fi 6 Wi-Fi 6E
Max Speed (theoretical) 3.5 Gbps 9.6 Gbps 9.6 Gbps
Frequency Bands 2.4 / 5 GHz 2.4 / 5 GHz 2.4 / 5 / 6 GHz
OFDMA No Yes Yes
Target Wake Time No Yes Yes

Should You Upgrade?

Here's a practical breakdown to help you decide:

  1. You have many connected devices: If you have 10+ devices competing for bandwidth, a Wi-Fi 6 router will noticeably reduce congestion and lag.
  2. You're already buying a new router: At similar price points, there's little reason to choose Wi-Fi 5 anymore.
  3. Your devices support it: Most smartphones and laptops from 2020 onward are Wi-Fi 6 compatible. Check your specs before assuming compatibility.
  4. Your internet plan is fast enough: If you're on a slow broadband plan, a Wi-Fi 6 router won't magically speed up your internet — it only helps you make better use of the bandwidth you already have.

Bottom Line

Wi-Fi 6 is a meaningful upgrade for anyone with a modern, device-heavy home. It won't double your internet speed overnight, but it will make your network feel more responsive and reliable — especially during peak usage. If your current router is more than three or four years old, it's a sensible time to make the switch.
