New modem technology has a way of making perfectly good hardware feel suddenly outdated. WiFi 7 modems are now widely available in Australia, and if you've been shopping around or noticed the spec sheets lately, you might be wondering whether it's time to upgrade or whether WiFi 6 is still doing the job just fine.
The honest answer? It depends on your household. This guide explains what's actually different between the two standards, who genuinely benefits from WiFi 7, and who can comfortably stick with what they have.
First, What Are We Actually Talking About?
Your nbn® connection brings the internet into your home, but it's your modem (sometimes called a router or modem-router) that takes that connection and distributes it wirelessly to every device in the house. The "WiFi 6" or "WiFi 7" label refers to the wireless standard the modem uses to do that job.
Think of it like the difference between a two-lane road and a four-lane motorway. The speed limit (your nbn® plan) stays the same, but a wider road can carry more traffic more smoothly, especially when things get busy.
WiFi 6 (802.11ax) has been the mainstream standard since around 2020. WiFi 7 (802.11be) is the latest generation, with hardware now widely available and device support growing rapidly.
What's Actually Different Between WiFi 6 and WiFi 7?
Speed
WiFi 6 supports theoretical maximum speeds of around 9.6 Gbps. WiFi 7 pushes that to a theoretical 46 Gbps, though in real-world home use, neither number is what you'll actually experience day-to-day. What matters is that WiFi 7 has significantly more headroom, which shows up as more consistent speeds when multiple devices are competing for bandwidth.
Multi-Link Operation (MLO)
This is WiFi 7's most meaningful new feature for home users. WiFi 6 devices connect to one frequency band at a time, either 2.4 GHz (longer range, slower) or 5 GHz (faster, shorter range). WiFi 7 introduces Multi-Link Operation, which lets a device connect across multiple bands simultaneously, pulling data from 2.4 GHz, 5 GHz, and 6 GHz at the same time. The result is faster speeds, lower latency, and a more stable connection, particularly in homes with a lot of competing wireless traffic.
Latency
Latency is the delay between your device sending a request and receiving a response. It's what makes online gaming feel snappy or laggy. WiFi 6 typically delivers around 10–20 ms of wireless latency. WiFi 7, thanks to MLO and improved signal processing, brings that closer to 5 ms or below in ideal conditions. For gaming, video calls, and real-time applications, that improvement is real and noticeable.
Channel Width
WiFi 7 supports wider 320 MHz channels in the 6 GHz band, compared to WiFi 6's maximum of 160 MHz. Wider channels mean more data can move at once, which is useful in demanding, high-device households. It's worth noting that Australia's 6 GHz spectrum regulations mean not all of this bandwidth is available locally, but there's still a meaningful performance benefit for households with newer devices.
Backward Compatibility
WiFi 7 modems work with all your existing WiFi 6, WiFi 5, and older devices so you don't need to replace anything else to benefit from the new hardware. Newer devices in the house will take full advantage of WiFi 7; older ones will simply connect as they always have.
Who Actually Benefits From Upgrading to WiFi 7?
You'll notice a real difference if:
You have a lot of devices. The average Aussie household already has 25 connected devices: phones, laptops, smart TVs, tablets, gaming consoles, smart speakers, security cameras, and more. WiFi 7's ability to handle more simultaneous connections without degrading performance is a tangible upgrade in a device-heavy home.
You game online. The latency reduction from WiFi 7 is most noticeable in fast-paced online games. If you're currently experiencing occasional lag spikes or inconsistent response times on WiFi, a WiFi 7 modem combined with MLO can deliver a noticeably more stable connection.
Multiple people work from home simultaneously. Video calls are sensitive to both speed and latency. If two or more people in your household are regularly on Zoom or Teams at the same time, WiFi 7's improved bandwidth management means everyone gets a more consistent experience with less pixelation and fewer freezes.
You're on a high-speed nbn® plan. If you're on nbn® 500/50 or above, a WiFi 6 modem can still handle those speeds, but a WiFi 7 modem gives you more headroom to actually use them across many devices at once without things slowing down under load.
You have a newer phone or laptop. Devices released from 2024 onwards increasingly include WiFi 7 chipsets. If your devices support the standard, you'll get a direct speed and stability benefit from pairing them with a WiFi 7 modem.
You're probably fine staying on WiFi 6 if:
Your current setup works well. If you rarely notice WiFi issues — no dead spots, no buffering, no lag — then there's no urgent reason to upgrade. WiFi 6 is a capable, mature standard that handles everyday household internet use very comfortably.
Most of your devices are older. The full benefits of WiFi 7 require devices that support it. If the majority of hardware in your home is a few years old, much of the upgrade will be wasted on hardware that can't take advantage of it.
You're on nbn® 50/20 or below. On lower-speed plans, your nbn® connection is the limiting factor, not your WiFi hardware. A faster modem won't meaningfully change your experience until the connection coming into your home is faster.
You've recently bought a WiFi 6 modem. WiFi 6 is not obsolete. It will remain a perfectly capable standard for years to come, and there's no practical reason to replace a recent, working modem simply because a newer generation exists.
A Note on the 6 GHz Band in Australia
WiFi 7's most powerful features rely on the 6 GHz frequency band. Australia has opened up part of the 6 GHz spectrum for indoor WiFi use, which is enough to deliver meaningful performance gains over WiFi 6 but not the full bandwidth available in the United States. In practice, this means Australian WiFi 7 users still see real improvements in speed and latency, though the absolute ceiling is slightly lower than international benchmarks suggest. It's not a reason to avoid WiFi 7, just worth knowing so you can calibrate your expectations.
What About Your nbn® Plan?
One thing to keep in mind: your modem and your nbn® plan work together. Upgrading your modem to WiFi 7 won't make a slow nbn® plan faster; the speed coming into your home is determined by your plan tier and connection type. But if you're on a fast nbn® plan and finding that speeds don't feel as quick as they should on certain devices, your modem could well be the bottleneck.

Our Pick for WiFi 7: The TP-Link HB210 Pro
If you've decided it's time to upgrade, we'll save you the hours of research. The TP-Link HB210 Pro is the modem we recommend for households on our higher-speed nbn® plans, and it's the exact reason it's the modem we stock and sell directly.
Here's why it stands out:
Built for fast nbn® speeds. The HB210 Pro comes with dual 2.5 GbE ports: one WAN and one LAN, which means it can actually handle the throughput of nbn® 500/50 and above without the port becoming a bottleneck. Many older modems max out at 1 Gbps on their Ethernet port, which quietly limits your wired speeds even on a faster plan.
Full WiFi 7 feature set. It supports Multi-Link Operation (MLO), 4K-QAM, OFDMA, MU-MIMO, and beamforming — the full suite of WiFi 7 technologies that make a real difference in device-heavy homes. Combined, these features allow it to handle 200+ connected devices simultaneously without the network grinding to a halt.
Dual-band speeds up to 3.6 Gbps. The HB210 Pro delivers up to 2880 Mbps on the 5 GHz band and 688 Mbps on 2.4 GHz. Well ahead of what your nbn® plan will ever push through, which means the modem is never the weak link in your setup.
Mesh-ready out of the box. One of the HB210 Pro's most practical features is its EasyMesh compatibility. If you have a larger home with dead spots or weak signal in certain rooms, you can simply add a second or third unit and they'll work together as a seamless mesh network — one network name, automatic handoff as you move around the house, no separate app or complicated setup required.
Simple setup, smart management. The HB210 Pro can be configured via the Aginet app on your phone or through a standard web interface — whichever you prefer. For Ezi Broadband customers, it also supports remote diagnostics, which means if you ever have a connection issue our support team can investigate without needing to walk you through technical steps over the phone.
It's available as a single unit, a 2-pack, or a 3-pack depending on the size of your home. Shop the TP-Link HB210 Pro here.
WiFi 7 is a genuine step forward, not just a marketing bump. But whether it's worth upgrading right now depends on your household.
Upgrade to WiFi 7 if you have a device-heavy home, you game online, multiple people work from home simultaneously, or you're on a high-speed nbn® plan and want to make the most of it.
Stick with WiFi 6 if your current setup works well, your devices are older, or you're on a lower-speed plan where the modem isn't the limiting factor.
If you are going to upgrade, look for a modem that supports MLO, has at least one 2.5 Gbps Ethernet port (to handle faster nbn® speeds), and is compatible with your nbn® connection type.
