WiFi 6 & WiFi 7 Explained

In New Zealand, we are lucky to have some of the best fiber infrastructure in the world. But here is a secret: your ultra-fast fiber plan is only as good as the WiFi router that distributes it. If you are paying for Gigabit or Hyperfibre but still seeing "buffering" icons in the bedroom, your WiFi standard is likely the bottleneck.

Today, the conversation is shifting from WiFi 6 (the current standard) to WiFi 7 (the future). In this guide, we’ll demystify these terms and help you decide if it’s time to upgrade your hardware or if your current setup is just fine.

WiFi Standards Demystified

Understanding WiFi standards used to require a degree in computer science. You might remember confusing labels like 802.11ac or 802.11n. Thankfully, the industry simplified things to help Kiwis compare broadband options more easily.

🧬 The Evolution: From WiFi 4 to WiFi 7

Each new generation of WiFi is designed to be faster, handle more devices simultaneously, and reach further through New Zealand’s often sturdy timber-framed or brick homes.

• WiFi 4 (802.11n): The old reliable, now mostly for basic smart home sensors.

• WiFi 5 (802.11ac): What most older NZ homes still use. It's "fine," but struggles when the whole family is streaming.

• WiFi 6 (802.11ax): The current "gold standard." It focuses on efficiency in busy households.

• WiFi 7 (802.11be): The newest arrival. It's built for "extreme" speeds and near-zero lag.

🏷️ Why the Naming Conventions Matter

The shift to simple numbers (6, 7) helps you identify compatibility at a glance. When you buy a new phone like an iPhone 16 or a Samsung Galaxy S24, you’ll see these symbols in your settings, telling you exactly which "engine" your connection is using. This is particularly important if you want to reach the average broadband speeds promised by your provider.

WiFi 6 (802.11ax): The Current Gold Standard

If you’ve upgraded your router or switched internet providers in the last 2–3 years, you likely have WiFi 6. It was a massive jump from WiFi 5 because it didn't just focus on top speed; it focused on congestion.

🚀 Key Improvements

• OFDMA: Imagine your WiFi data as a delivery truck. In older standards, one truck carried one package to one device. WiFi 6 allows one truck to carry packages for multiple devices at once.

• Target Wake Time: This helps your smartphones and smart home devices "sleep" when not transmitting, significantly improving battery life.

🏠 Real-World Benefits for NZ Homes

WiFi 6 is perfect for the "connected Kiwi home." If you have 20+ devices (smart TVs, laptops, phones, and a Ring doorbell), WiFi 6 ensures they aren't all fighting for the same "lane" on the digital highway. It provides a stable experience for standard Fibre 300 and Gigabit plans.

WiFi 7 (802.11be): The Future of Fast

WiFi 7 is the "Hyperfibre" of the wireless world. It is designed to handle speeds that seem impossible - up to 46Gbps in theory (though you'll see closer to 2-5Gbps in real-world NZ home conditions).

✨ What’s New?

• 320MHz Channels: WiFi 7 doubles the width of the data lanes compared to WiFi 6. Think of it as doubling the lanes on the Auckland Harbour Bridge.

• Multi-Link Operation (MLO): This is the "killer feature." Previously, your phone connected to either the 2.4GHz or 5GHz band. WiFi 7 allows a device to connect to both at the same time, using whichever is faster at that exact millisecond.

• 4K-QAM: This packs 20% more data into every signal pulse, making every "blink" of your WiFi more efficient.

💡 When to Consider WiFi 7

You should look at WiFi 7 if you are an early adopter using Hyperfibre 2, 4, or 8 plans. Without a WiFi 7 router, you simply cannot experience those multi-gigabit speeds wirelessly on your mobile devices. It's also the new benchmark for the best gaming broadband experience in NZ.

Do You Need to Upgrade?

The honest answer depends on your internet plan and your hardware.

✅ When WiFi 6 is Worth It

• You're still on WiFi 5: If your router is more than 4 years old, moving to WiFi 6 is the best "bang for your buck" upgrade you can make.

• You have a large family: If multiple people stream 4K or play games at once, WiFi 6 will solve your "lag" issues.

🛑 When WiFi 7 is Overkill

• You don't have WiFi 7 devices: To use WiFi 7 speeds, both the router and your phone/laptop must support it.

• Your plan is Fibre 300: If you aren't on a Gigabit or Hyperfibre plan, WiFi 7 is like buying a Ferrari to drive to the local dairy, it’s cool, but you can’t use its power.

WiFi 6 & WiFi 7 Routers in NZ

Ready to make the jump? Here are some of the best modems and routers available at major NZ retailers like PB Tech and Harvey Norman.

🇳🇿 Recommended Models for Kiwis

📞 ISP-Provided vs. Buying Your Own

Before buying, check with your broadband provider. Many major players like Spark, 2degrees, and One NZ now offer WiFi 6 routers for free on 12-month contracts, or allow you to "add-on" a WiFi 7 mesh system for a monthly fee.

Frequently Asked Questions (FAQ)

Q: Will WiFi 7 make my internet faster?

A: Only if your internet plan is faster than 1Gbps (like Hyperfibre) and your device supports WiFi 7. For most people, it will improve reliability more than raw speed.

Q: Is WiFi 7 backwards compatible?

A: Yes. Your old iPad or laptop will still connect to a WiFi 7 router, but they will only run at their original speeds (WiFi 4 or 5).

Q: Do I need new cables for WiFi 7?

A: To get the full 10Gbps potential, you should use Cat6a or Cat7 ethernet cables to connect your ONT setup to your router.
