Wi-Fi 6 vs Wi-Fi 6E vs Wi-Fi 7: What Changes and Should You Upgrade?

Router boxes now shout Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7, with speed numbers in the tens of gigabits. Those numbers describe laboratory maximums that no home ever sees. What matters is what each generation changes in a real apartment or house, and whether your phones and laptops can use it. Here is the difference in plain words, and a simple way to decide whether to upgrade.

At a Glance

All three are backward compatible: an older laptop connects to a Wi-Fi 7 router, just at its own older speed.

Wi-Fi 6: Better in Busy Homes

Wi-Fi 6 was less about top speed and more about efficiency. Technologies such as OFDMA and target wake time let the router serve many devices at once in smaller slices and let battery devices sleep longer. In a home full of phones, TVs, cameras and smart plugs, that means fewer slowdowns when everyone is online. Wi-Fi 6 also brought 1024-QAM, which squeezes more data into each transmission when the signal is strong.

For many homes, a good Wi-Fi 6 router is still all they need: it delivers several hundred megabits per second to a modern device in the same room, which covers most internet plans.

Wi-Fi 6E: A New, Empty Band

Wi-Fi 6E is Wi-Fi 6 extended into the 6 GHz band. That band has far more room for wide channels than 5 GHz and, crucially, almost no older devices or neighbors using it yet. In apartment buildings, where 2.4 and 5 GHz are crowded, moving to 6 GHz can make a bigger difference than any other upgrade.

The trade-off is range. Higher frequencies pass through walls and floors less well, so 6 GHz is at its best in the same room or the next one. Which parts of the 6 GHz band are allowed also depends on the country, so availability varies.

Wi-Fi 7: Wider Channels and Multi-Link

According to the Wi-Fi Alliance, which certifies devices, Wi-Fi 7 brings three main improvements:

• 320 MHz channels in the 6 GHz band, twice as wide as Wi-Fi 6’s widest, which roughly doubles the possible throughput.
• 4K QAM, which carries about 20% more data per transmission than Wi-Fi 6’s 1024-QAM when the signal is strong.
• Multi-Link Operation (MLO), which lets a device use more than one band at the same time or switch between them instantly, improving speed and reliability.

In practice, Wi-Fi 7 shines close to the router with Wi-Fi 7 devices: very fast local transfers, lower and steadier latency, and faster connections on multi-gigabit internet plans. Multi-Link Operation also helps consistency, which matters for gaming and video calls. Wi-Fi 7 routers often come with 2.5 Gbps or faster wired ports, which you need to pass a fast plan through at all.

Your Devices Decide What You Get

A new router only helps devices that support the new features. A Wi-Fi 5 laptop on a Wi-Fi 7 router stays a Wi-Fi 5 laptop; it may connect a bit better thanks to the router’s stronger hardware, but it cannot use 6 GHz, 320 MHz channels or MLO.

Most phones and laptops from the last few years support Wi-Fi 6, recent flagship phones and laptops add 6E or 7, and smart-home gadgets mostly stay on 2.4 GHz Wi-Fi 4 because they need range, not speed. Before paying for Wi-Fi 7, check the devices you use most.

How to Check Your Wi-Fi Version

Windows: open Command Prompt and run netsh wlan show interfaces. The “Radio type” line shows the standard in use: 802.11ac is Wi-Fi 5, 802.11ax is Wi-Fi 6 or 6E, 802.11be is Wi-Fi 7. The “Band” line shows whether you are on 2.4, 5 or 6 GHz.

Mac: hold the Option key and click the Wi-Fi icon in the menu bar. The PHY Mode line shows the standard (802.11ax and so on) and the Channel line shows the band.

Router: the model name on the label tells you the generation; look it up on the maker’s site. Our router brand pages list models and their default login details.

Should You Upgrade?

Stay with Wi-Fi 6 if your router is Wi-Fi 6, your plan is under about 1 Gbps, your home is not crowded with neighbors’ networks and your devices are mostly Wi-Fi 6 or older. Better placement or a mesh system will help more than a new generation. See how to boost your Wi-Fi signal.

Consider Wi-Fi 6E or 7 if you live in an apartment building with crowded 5 GHz, have several 6E or Wi-Fi 7 devices, or work and game in rooms close to the router.

Choose Wi-Fi 7 if you have, or plan to get, a multi-gigabit internet plan, you are replacing a router older than Wi-Fi 6 anyway, or you are buying a mesh system for a large home, where Multi-Link Operation and 6 GHz backhaul between units make a real difference.

Replace anything older than Wi-Fi 5. A Wi-Fi 4 router limits every device and often no longer gets security updates; check whether yours still receives firmware updates. When you replace it, our guide on how to set up a new router helps your devices move over without trouble.
