Wi-Fi 6: What Is It and Is It Worth Upgrading?

Jun 09, 2026

Remember when Wi-Fi only had to deal with a laptop and someone watching YouTube? Simpler times.

Now your poor router’s managing:

Two people working from home
Three TVs streaming simultaneously
A PlayStation downloading updates the size of films
Smart speakers always one accidental wake word away from “sorry, I didn’t catch that”
Cameras uploading footage
Phones backing up photos

And despite all this, we still expect the Wi-Fi to behave flawlessly. Bold, really.

Wi-Fi 6 was introduced to handle exactly this kind of connected lifestyle. The older, more sophisticated sibling of Wi-Fi 5, it brings faster speeds, lower congestion and a much savvier way of managing busy networks.

So, let's get into what makes Wi-Fi 6 so great and why we include it as standard with every Fusion Fibre broadband package.

What Is Wi-Fi 6?

Wi-Fi 6 helps modern networks do what modern networks are constantly being asked to do: more. Officially known as 802.11ax, it sits alongside earlier generations like 802.11ac (Wi-Fi 5).

Wi-Fi 6 improves just about every part of your wireless connection.

It offers:

Faster speeds
Better reliability
Improved efficiency
Stronger performance on busy networks
Better handling of multiple connected devices

Which is wonderful news given that your house has likely got:

Phones endlessly refreshing apps
Laptops surviving back-to-back Teams calls
Smart TVs chewing through 4K box sets
Games consoles downloading updates larger than the games themselves
Tablets scattered around the house like a minor infestation
Smart speakers waiting patiently for someone to accidentally summon them
Security cameras keeping watch
Video doorbells keeping score
Streaming devices putting in overtime

Twenty years ago, that would've looked like a small office. Now? It's just another Tuesday evening.

How Fast Is Wi-Fi 6?

Wi-Fi 6 is significantly faster than Wi-Fi 5, at least on paper.

While Wi-Fi 5 tops out at a theoretical 3.5 Gbps, Wi-Fi 6 turns up with a considerably less modest 9.6 Gbps.

It’s important to remember though, that real-life Wi-Fi rarely behaves like the numbers on the box.

A theoretical speed is exactly that: theoretical. These figures are measured under ideal lab conditions, while real-world performance depends on things like:

Your broadband package
Router quality
Distance from the router
Wall thickness
Network congestion
How many devices are connected

So no, upgrading to Wi-Fi 6 won’t suddenly make your internet 10x faster overnight.

What it will do is help your Wi-Fi handle heavier workloads without slowing you down.

How Does Wi-Fi 6 Improve Your Internet?

Better Performance With Multiple Devices

Older Wi-Fi standards tend to start waving the white flag when too many devices jump online at once.

That's when the usual symptoms appear:

Buffering during streams
Lag in games and video calls
Slow downloads
Random connection dropouts
Video calls freezing on deeply unfortunate facial expressions

Wi-Fi 6 is far better equipped to handle the chaos of a modern home network.

Technologies like OFDMA allow the router to communicate with multiple devices simultaneously instead of forcing every phone, TV, laptop and smart gadget into a bandwidth waiting room.

So rather than performance taking a nosedive the moment everyone gets online, Wi-Fi 6 keeps things ticking along a lot more smoothly.

Exactly as good Wi-Fi should.

Faster, More Stable Speeds

Yes, Wi-Fi 6 is faster. But speed is an easy metric to ace when there's hardly anything happening on the network.

The real challenge is maintaining performance when multiple devices are all competing for attention at once.

Whether you're streaming in 4K, gaming online, downloading large files, backing up photos or working from home, Wi-Fi 6 helps keep performance consistent across the board.

Reduced Network Congestion

The more crowded your area, the harder your Wi-Fi has to work.

In flats, apartment blocks and densely populated streets, dozens of routers have to battle it out for the same wireless channels.

This interference

Slower speeds
Unstable connections
Dropouts
Poor performance during busy hours

Wi-Fi 6 helps bring order to the chaos with a feature called BSS Colouring.

It allows devices to recognise which Wi-Fi signals belong to their own network and which belong to the neighbours.

In other words, your Wi-Fi is less likely to get distracted by what the neighbours are doing.

Lower Latency

If speed is how fast your network can move, latency is how quickly it can react.

The lower the latency, the more responsive everything feels. The higher it gets, the more likely you are to experience the usual string of online headaches like lag and buffering.

Wi-Fi 6 was built with low latency in mind, which is a huge bonus for:

Gaming
Streaming
Video calls
Real-time apps
Smart home devices

Better Battery Life for Devices

Wi-Fi 6 is smarter with power usage too.

A nifty little feature called Target Wake Time (TWT) allows devices to schedule when they communicate with the router instead of constantly checking in.

Less background activity also means less power consumption and more time between charges. Which is fabulous news for your devices and the planet. Win-win.

Key Wi-Fi 6 Features Explained

Wi-Fi 6 introduces plenty of acronyms, none of which are particularly good at explaining themselves.

Fortunately, their job is much simpler than their names suggest: fixing common Wi-Fi frustrations like:

Lag
Buffering
Slowdowns
Congestion

OFDMA

One of the biggest challenges for older Wi-Fi standards is dealing with multiple requests at once.

They're often forced to handle network traffic in sequence, with each request politely waiting its turn.

OFDMA changes that by allowing routers to communicate with multiple devices simultaneously,

MU-MIMO

MU-MIMO stands for Multi-User, Multiple Input, Multiple Output. A name only an engineer could love.

In simple terms, it helps your router handle lots of simultaneous connections more efficiently. Which matters when your Wi-Fi’s juggling a house full of screens and streams.

Wi-Fi 6 improves MU-MIMO significantly, helping your network stay responsive even when everyone’s online at once. Which is increasingly every minute of every day.

1024-QAM

1024-QAM allows more data to be packed into each wireless signal, helping your router move information around faster and more efficiently.

That means:

Faster wireless speeds
Better efficiency
Improved overall performance

It’s one of the core reasons Wi-Fi 6 feels quicker and less overwhelmed than older Wi-Fi standards.

Target Wake Time (TWT)

Wi-Fi 6 gets smarter with battery life too.

A feature called Target Wake Time (TWT) allows devices to schedule when they communicate with the router instead of constantly checking in all day like older standards.

That means:

Less unnecessary background activity
Lower power usage
Better battery life for connected devices

Do You Need a Wi-Fi 6 Router?

Yep. To use Wi-Fi 6, you’ll need:

A Wi-Fi 6 router
Wi-Fi 6 compatible devices

The good news is that Wi-Fi 6 is fully backward compatible, so older devices still work perfectly fine. They just won’t benefit from the full set of Wi-Fi 6 features.
