Wi-Fi 7 arrives at home: is it worth upgrading?

What Wi-Fi 7 is

Wi-Fi standards are numbered by generation. Wi-Fi 5 and Wi-Fi 6 are in most homes today. Wi-Fi 7 is the newest. The Wi-Fi Alliance, the industry group that tests devices so they work together, began certifying Wi-Fi 7 products in January 2024, and by 2026 Wi-Fi 7 routers, mesh systems, phones and laptops are widely sold.

What it improves

• Multi-Link Operation (MLO): a device can use more than one band at once, for example 5 GHz and 6 GHz together. If one is busy, traffic flows on the other. Think of a car that can use two motorway lanes at the same time.
• Wider channels: up to 320 MHz in the 6 GHz band, double Wi-Fi 6E's maximum, which means more data at once where there is space.
• Denser signals: a technique called 4K-QAM packs more data into each radio wave when the signal is strong.
• Lower and steadier delay: useful for video calls, gaming and virtual reality.

The catch: both ends must support it

A Wi-Fi 7 router talks to older devices using their older standards, so it will not make an old laptop faster on its own. You see the gains when the phone or laptop also supports Wi-Fi 7. The 6 GHz band also does not travel through walls as well as 2.4 GHz, so coverage still depends on where the router sits. In some countries, use of the 6 GHz band is still restricted or limited.

Should you upgrade?

• Probably not yet if your current router is Wi-Fi 6, coverage is good and your broadband is under a few hundred Mbps.
• Consider it if you are buying a new router anyway, have gigabit broadband, a busy household with many devices, or new phones and laptops that support Wi-Fi 7.
• Fix coverage first: a mesh system or a better router position often helps more than a new standard. See Wi-Fi vs Ethernet.

Tip: If you upgrade, turn on WPA3 security, which Wi-Fi 6E and Wi-Fi 7 require on the 6 GHz band.

What comes next

Work on the next generation, often called Wi-Fi 8, is focused less on top speed and more on reliability: keeping connections steady as you move around and in crowded places. For most people, though, Wi-Fi 7 will be the standard they meet in new devices over the next few years.

Reading the box

Router boxes are full of big numbers, such as "BE19000". These add up the theoretical maximum of every band together, a speed no single device will ever see. Look instead for the things that affect you: the Wi-Fi generation (Wi-Fi 7, sometimes written 802.11be), whether it supports the 6 GHz band in your country, how many years of security updates the maker promises, and whether it can be expanded into a mesh system later. For a large or awkward home, two or three mid-range mesh units usually beat one expensive router in the hallway.
