Wi-Fi 6, 6E and 7 explained: do you need to upgrade?

By E11 Apps, the developer of CellRadar. Updated . 5 min read.

Wi-Fi 6 copes better with many devices at once, Wi-Fi 6E adds the less crowded 6 GHz band, and Wi-Fi 7 adds very wide channels and the ability to use several bands together. When weighing Wi-Fi 6 vs Wi-Fi 7, the honest answer is that an upgrade only helps if your devices support the new standard and your current Wi-Fi, not your broadband, is the bottleneck.

What the numbers mean

Wi-Fi standards used to have technical names like 802.11n and 802.11ac. The Wi-Fi Alliance, the industry group behind Wi-Fi certification, later gave them simple numbers:

  • Wi-Fi 4 is 802.11n.
  • Wi-Fi 5 is 802.11ac.
  • Wi-Fi 6 is 802.11ax.
  • Wi-Fi 6E is 802.11ax extended to the 6 GHz band.
  • Wi-Fi 7 is 802.11be.

Each new standard works with older devices. A Wi-Fi 5 laptop connects to a Wi-Fi 7 router fine; it just uses Wi-Fi 5 features.

Wi-Fi 6: built for busy homes

Wi-Fi 6 focused less on peak speed and more on handling many devices at once, which suits homes full of phones, laptops, TVs and smart gadgets. The main changes:

  • OFDMA lets the router split a channel into smaller pieces and serve several devices in a single transmission, instead of making each one wait its turn.
  • Better MU-MIMO allows the router to send to more devices at the same time.
  • Target wake time lets devices schedule when they wake to talk to the router, which can save battery on phones and smart devices.

Wi-Fi 6 works on 2.4 GHz and 5 GHz.

Wi-Fi 6E: a new, quieter band

Wi-Fi 6E is Wi-Fi 6 with access to the 6 GHz band. That band is far less crowded because only 6E and newer devices can use it, and it has room for many wide channels. The trade-off is range: 6 GHz fades faster through walls than 5 GHz. How much of the 6 GHz band is available depends on your country.

For a side-by-side look at the three bands, see 2.4 GHz vs 5 GHz vs 6 GHz Wi-Fi.

Wi-Fi 7 builds on Wi-Fi 6 and 6E with a few big changes:

  • 320 MHz channels in the 6 GHz band, double the widest channel Wi-Fi 6E allows, for higher peak speeds.
  • Multi-link operation (MLO), which lets a device connect over more than one band at the same time. It can send data on whichever link is clearest, or on several at once, which helps with steadiness and delay.
  • 4096-QAM, a denser way of packing data into the signal that raises speed when the signal is very strong.

Wi-Fi 7 also works on 2.4 GHz and 5 GHz, so older devices are still covered.

Wi-Fi 6 vs Wi-Fi 7: what changes for you

On paper, Wi-Fi 7 is far faster. In a real home, the difference depends on three things.

  1. Your devices. You only get Wi-Fi 7 features on devices that support Wi-Fi 7. A house of older phones and laptops sees little change.
  2. Your broadband. If your internet plan is slower than what Wi-Fi 6 already delivers in your rooms, a Wi-Fi 7 router cannot make the internet itself faster. It may still help with transfers inside the home, such as backups to a network drive.
  3. Your coverage. A new standard does not fix walls and distance. If the problem is a weak signal in far rooms, mesh Wi-Fi or an extender or better router placement matters more.

When an upgrade makes sense

The Wi-Fi 6 vs Wi-Fi 7 choice only matters once you have decided your router is holding you back. Upgrading is worth considering if:

  • your router only supports Wi-Fi 5 or older and you have many devices
  • you have fast broadband and your speed tests on Wi-Fi are well below what you get on a cable
  • you live in a crowded area and your phones and laptops support 6 GHz
  • you need low, steady delay for gaming or video calls and your devices support Wi-Fi 7

When it does not

Hold off if:

  • your devices are mostly older and do not support the newer standards
  • a cable test gives the same speed as Wi-Fi, which means the broadband line is your limit
  • your problem is a single far room, which is a coverage issue

How to check what you have

Your router's label or settings page usually names its Wi-Fi standard. For your phone, check the maker's specifications. A Wi-Fi analyzer can also show which standard nearby networks use, including your own.

Then, before you weigh up Wi-Fi 6 vs Wi-Fi 7, compare a speed test over Wi-Fi near the router with your broadband plan's speed. If they are close, your Wi-Fi is already keeping up.

How CellRadar helps

CellRadar's Wi-Fi Analyzer shows nearby networks with Wi-Fi 6, 6E and 7 support, along with band, channel and signal, so you can see what your router and neighbours are running. The speed test measures download, upload, ping and jitter, which helps you judge whether your Wi-Fi or your broadband is the limit before you spend money.

Frequently asked questions

Will a Wi-Fi 7 router make my internet faster?

Only if your Wi-Fi is currently slower than your broadband. It cannot raise the speed of the line coming into your home.

Do my old devices work with Wi-Fi 7?

Yes. Wi-Fi 7 routers support older devices, which connect using their own standard.

Is Wi-Fi 6E worth it over Wi-Fi 6?

It can be in busy areas, if your devices support 6 GHz and you use them near the router. In quieter areas or with older devices, the gain is smaller.

Is Wi-Fi 7 better than Wi-Fi 6 for gaming?

Wi-Fi 7 can offer steadier delay through multi-link operation, but only on supported devices. A cable is still the most reliable option for gaming.
