WiFi 6, 6E & 7 Explained for Canadians
WiFi standards are confusing. This guide explains each generation in plain language, compares them honestly, and helps you decide what to buy in 2026.
The Quick Overview
WiFi has gone through several generations, each with a confusing technical name. The WiFi Alliance simplified things by giving each generation a number. Here are the four you will encounter in 2026:
Important context: Those “max speed” numbers are theoretical maximums under perfect lab conditions. You will never see 46 Gbps in your living room. Real-world speeds depend on your internet plan, your router, the distance to the router, walls, interference, and whether your device supports the same WiFi standard. What matters more is the features each generation brings, which we will explain below.

🔵 WiFi 6 (802.11ax)
WiFi 6 was released in 2019 and is now the baseline standard in most homes and devices. If you bought a phone, laptop, or router in the last 3 to 4 years, there is a very good chance it supports WiFi 6. This is the generation that shifted focus from raw speed to handling lots of devices efficiently.
Before WiFi 6, your router could only talk to one device at a time, then quickly switch to the next. It was fast enough that you did not notice, until you had 15 devices all competing for attention. WiFi 6 introduced OFDMA, which lets the router communicate with multiple devices simultaneously in a single transmission. It also introduced Target Wake Time (TWT), which lets devices “sleep” and only wake up to check in at scheduled intervals, saving battery on phones and IoT gadgets.
WiFi 6 in plain language: Your old router was like a waiter who could serve one table at a time. WiFi 6 is a waiter who can serve four tables at once without mixing up the orders.
Should you still buy WiFi 6 in 2026? As a standalone purchase, WiFi 6 routers are now the budget option. They are perfectly fine for basic households with under 15 devices, internet plans under 500 Mbps, and no particular need for the 6 GHz band. If you live in a house (not a dense apartment) with a moderate internet plan, WiFi 6 will serve you well for a few more years.
🟣 WiFi 6E (802.11ax Extended)
WiFi 6E uses the exact same technology as WiFi 6, with one critical addition: it unlocks the 6 GHz frequency band. This matters far more than it sounds.
The 2.4 GHz and 5 GHz bands have been used by WiFi since the beginning. In a Canadian apartment building with 50+ units, those bands are extremely congested. Every router, baby monitor, Bluetooth device, and microwave oven competes for the same airspace. The 6 GHz band is like opening a brand-new, empty highway. In Canada, it provides up to 59 additional channels with virtually no interference from older devices (because they cannot see it).
WiFi 6E in plain language: Imagine your neighbourhood only has two roads (2.4 GHz and 5 GHz), and they are always jammed during rush hour. WiFi 6E builds a third highway (6 GHz) that only newer cars can use. Suddenly, your commute is wide open.
The tradeoff is that 6 GHz has shorter range than 5 GHz, which has shorter range than 2.4 GHz. In a large house, you may not get 6 GHz signal in the far corners. But in an apartment or condo, where distance is short and congestion is high, WiFi 6E is a game-changer.
WiFi 6E is the sweet spot for most Canadians in 2026. It offers the best balance of price, performance, and device compatibility. Most mid-range to high-end phones, laptops, and tablets released since 2022 support WiFi 6E. Routers cost $150 to $300 CAD. If you live in an apartment, condo, or townhouse with lots of neighbouring WiFi networks, 6E makes a huge difference.
🟠 WiFi 7 (802.11be)
WiFi 7 is the newest standard, with the specification finalized by the IEEE in July 2025. Routers have been available since early 2024 (based on draft specifications), and as of 2026, a growing number of flagship devices support it.
WiFi 7 operates on the same three bands as WiFi 6E (2.4, 5, and 6 GHz) but adds several major technical improvements. The headline feature is Multi-Link Operation (MLO), which allows a device to use multiple bands simultaneously. Previous WiFi standards forced each device to use one band at a time. MLO is like upgrading from a single-lane road to a three-lane highway where you can drive in all lanes at once.
Other improvements include 320 MHz ultra-wide channels (double the width of WiFi 6E’s maximum), 4096-QAM modulation (packing 20% more data per signal), and Preamble Puncturing (which lets the router skip around interference instead of avoiding entire channels).
Who benefits from WiFi 7 right now?
- Gamers and streamers: MLO can reduce worst-case latency by up to 100 times. For cloud gaming and VR, this is significant.
- Multi-gigabit fibre subscribers: If you have 2 Gbps+ fibre, WiFi 6E routers can bottleneck around 1.5 to 2 Gbps. WiFi 7 with 10G ports can actually deliver your full speed wirelessly.
- Dense smart homes: If you have 30+ connected devices, WiFi 7’s improved capacity and coordination helps.
- Future-proofers: A WiFi 7 router bought today will remain top-tier for 5+ years.
The catch in 2026: You only get WiFi 7 benefits when both the router and the connecting device support it. As of early 2026, WiFi 7 is available on iPhone 16 series (Pro models get full MLO), Samsung Galaxy S24 Ultra, S25 series, Google Pixel 9 Pro, select high-end laptops (Dell XPS, Alienware, ASUS ROG), and some gaming devices. Budget and mid-range phones (Galaxy A series, Pixel 9a) are still WiFi 6E only. Your older devices will still work on a WiFi 7 router, they just will not use the new features.

📱 Which Devices Support What? (2026)
You only get the benefits of a WiFi standard when both your router and your device support it. Here is what the major devices support as of early 2026:
| Device | WiFi Standard |
|---|---|
| iPhone 16 Pro / Pro Max | WiFi 7 (with MLO) |
| iPhone 16 / 16 Plus | WiFi 7 |
| iPhone 15 Pro / Pro Max | WiFi 6E |
| iPhone 15 / 14 / 13 | WiFi 6 |
| Samsung Galaxy S25 series | WiFi 7 |
| Samsung Galaxy S24 Ultra | WiFi 7 |
| Samsung Galaxy S24 / S24+ | WiFi 6E |
| Google Pixel 9 Pro | WiFi 7 |
| Google Pixel 8 / 8 Pro | WiFi 6E |
| MacBook Pro/Air (M3, M4) | WiFi 6E |
| High-end Windows laptops (2025+) | WiFi 7 (select models) |
| PlayStation 5 | WiFi 6 |
| Xbox Series X/S | WiFi 5 |
| Most smart home devices | WiFi 4 or 5 |
Key takeaway: Your gaming console, smart TV, and smart home gadgets are likely still on WiFi 5 or 6. They will work fine on any newer router (backward compatible), but they will not take advantage of 6E or 7 features. The devices that benefit most from upgrading are your phone and laptop, since those are the ones you use most heavily.
Frequently Asked Questions
They use the same 802.11ax technology. The only difference is that WiFi 6E adds access to the 6 GHz band, which provides up to 59 additional channels in Canada with virtually no congestion. WiFi 6 operates on 2.4 and 5 GHz only. Think of 6E as WiFi 6 with an extra, empty highway lane added.
If you have multi-gigabit fibre and flagship devices (iPhone 16, Galaxy S25), WiFi 7 is a solid future-proof investment. If most of your devices are still WiFi 6 or 6E, a WiFi 6E router gives you better value right now. WiFi 7 routers are backward compatible, so they work with all your existing devices.
A new router can make your WiFi faster, but it cannot exceed your internet plan speed. If you pay for 300 Mbps, a WiFi 7 router will not give you 500 Mbps. However, a newer router can help you actually reach the speed you are paying for, especially if your current router is old or struggling with interference.
MLO is WiFi 7’s most important feature. It lets a device connect across 2.4, 5, and 6 GHz bands simultaneously. Previous standards used one band at a time. MLO dramatically improves speed and reliability, especially for gaming, video calls, and VR, because if one band has interference, traffic instantly reroutes through the others.
Yes. WiFi 7 routers work with WiFi 6E, 6, 5, and older devices. Your older phone or laptop connects and works fine; it just will not use the WiFi 7 features. Only devices with 802.11be support can access MLO and the other WiFi 7 improvements.
The most common causes are poor router placement (in a closet or on the floor), your devices connecting to the crowded 2.4 GHz band instead of 5 GHz, interference from neighbours’ routers on the same channel, and older devices that do not support your router’s fastest speeds.
