What is Wi-Fi 7, and do you need a new router?

Wi-Fi 7 is the newest Wi-Fi standard. It is faster and steadier than Wi-Fi 6, but only if your router and your devices both support it. For most homes there is no rush.

Technical name: IEEE 802.11be
Certified since: January 2024
Bands: 2.4 GHz, 5 GHz and 6 GHz
Widest channel: 320 MHz (in the 6 GHz band)

Wi-Fi comes in generations, like mobile networks. Wi-Fi 5 arrived in 2013, Wi-Fi 6 in 2019, Wi-Fi 6E added a new band in 2020, and Wi-Fi 7 has been certified by the Wi-Fi Alliance since January 2024. New phones, laptops and routers increasingly carry the Wi-Fi 7 label.

What Wi-Fi 7 changes

Wider channels

A wider channel carries more data at once, like a road with more lanes. Diagram: How To, Simply.

Think of a channel as a road. Wi-Fi 6 roads are up to 160 MHz wide. Wi-Fi 7 allows 320 MHz in the 6 GHz band, so twice as much data can travel at once.

More data per signal

Wi-Fi 7 packs more information into each radio signal, using a method called 4096-QAM (Wi-Fi 6 uses 1024-QAM). In good conditions close to the router this adds roughly 20% more speed.

Multi-Link Operation

This is the change you are most likely to notice. Older Wi-Fi connects a device on one band at a time: 2.4, 5 or 6 GHz. With Multi-Link Operation, or MLO, a device can use two or more bands together. If one band is busy or blocked by a wall, traffic moves to another without a pause. That means steadier video calls and games, not only higher top speeds.

What you need to use it

A Wi-Fi 7 router, and
a Wi-Fi 7 device. A Wi-Fi 6 phone connected to a Wi-Fi 7 router still works, but at Wi-Fi 6 speeds.

Wi-Fi 7 routers work with all your older devices. Nothing stops working when you upgrade.

The 6 GHz band, where the widest channels live, is not allowed in the same way in every country. Where it is restricted, Wi-Fi 7 still brings MLO and the other improvements on 2.4 and 5 GHz.

Will it make your internet faster?

Only up to the speed you pay for. Wi-Fi is the link between your devices and the router. Your internet plan is the link between the router and the outside world. If your plan is 100 Mbit/s, a Wi-Fi 6 router already delivers all of it, and Wi-Fi 7 cannot add more. The gains show up with very fast fibre plans, when moving large files between devices at home, and in crowded homes with many devices online at once.

Should you buy a Wi-Fi 7 router?

Buy now if your router is Wi-Fi 5 or older, you are replacing it anyway, and the price difference to Wi-Fi 6 is small where you live.
Wait if you have a working Wi-Fi 6 or 6E router and an internet plan under about 500 Mbit/s. You would see little difference.
Fix the basics first if your problem is weak signal in some rooms. Router position matters more than the Wi-Fi generation: place it high, in the open and near the middle of the home, or add a mesh point.

How to check what you have

The router's label or its settings page lists the standard as Wi-Fi 6, Wi-Fi 7, or as 802.11ax (Wi-Fi 6) and 802.11be (Wi-Fi 7). For a phone or laptop, look up the model's technical specifications on the maker's website.

Questions readers ask

Will Wi-Fi 7 work with my old devices?

Yes. A Wi-Fi 7 router works with older phones, laptops and smart home devices. They connect at their own, older speeds.

Does Wi-Fi 7 make my internet faster?

Only up to the speed of your internet plan. It makes the wireless link inside your home faster and steadier, not the line coming into it.

What is the difference between Wi-Fi 6E and Wi-Fi 7?

Both can use the 6 GHz band. Wi-Fi 7 adds channels twice as wide and lets a device use several bands at the same time.

Do I need a new phone for Wi-Fi 7?

To get Wi-Fi 7 speeds, yes: both the router and the device must support it. Check the technical specifications of your model.
