Wi-Fi 6E and Wi-Fi 7: Why Your Internet Is Slow (and It's Not Your Provider)

You're paying for 500 Mbps Internet from Bell or Rogers, but when you run a speed test on your laptop, you get 80 Mbps. You call your provider, they test the line, everything's fine on their end. So what's the problem?

The problem is almost always between your router and your devices — the local Wi-Fi network. It's like having a 6-lane highway (your plan) that turns into a one-lane gravel road (your old router) before reaching your house.

Two things need to be up to date for your connection to be fast: the router (the box that broadcasts the signal) AND the Wi-Fi card in your computer. If either one is old, it's the weak link that dictates your actual speed.

Wi-Fi 5 (802.11ac) — released in 2014. Max theoretical speed: ~1.3 Gbps. Uses the 2.4 GHz and 5 GHz bands. This is what you still find in a lot of routers provided by cable companies. Decent, but getting dated.

Wi-Fi 6 (802.11ax) — released in 2020. Max speed: ~9.6 Gbps. The big improvement: it handles environments with lots of connected devices much better (phones, tablets, smart TVs, thermostats, smart bulbs). It's the minimum recommended in 2026.

Wi-Fi 6E — same technology as Wi-Fi 6, but with access to the 6 GHz band. This band is less congested (fewer neighbours on it) and offers more stable speeds. It's the current sweet spot — fast, reliable, and the gear is affordable.

Wi-Fi 7 (802.11be) — the latest generation. Max theoretical speed: ~46 Gbps. Can use all 3 bands simultaneously (2.4 + 5 + 6 GHz). Excellent but compatible routers and devices are still pricey. It's the 2027 car — impressive, but not necessary just yet.

Wi-Fi uses radio frequencies (like FM radio, but for Internet). Each band has its strengths. 2.4 GHz: goes through walls well, long range, but slower and crowded (your neighbours, the microwave, and Bluetooth devices are all on it). Ideal for devices far from the router.

5 GHz: faster, less crowded, but worse at going through walls and floors. Ideal when you're in the same room or one wall away from the router.

6 GHz (Wi-Fi 6E and 7): the fastest, least crowded (very few devices use it yet), but shorter range. Ideal for recent devices close to the router — 4K streaming, video calls, gaming.

In car terms: 2.4 GHz is the country road — you go far but not fast. 5 GHz is the highway — fast but doesn't go everywhere. 6 GHz is the F1 circuit — ultra-fast, but reserved for those with the right equipment.

Step 1: check your router. Flip it over and look at the model. If it says Wi-Fi 5, AC, or if it's from before 2020, that's your bottleneck. Contact your provider to replace it (often free) or buy a Wi-Fi 6E router for $100-200.

Step 2: check your laptop. In Windows, type "Device Manager" then go to "Network adapters" and look at the name of your Wi-Fi card. If it says "Wi-Fi 5" or "802.11ac," that's your second bottleneck. Laptops from 2022+ generally have Wi-Fi 6.

Step 3: router placement. Put it up high, in the centre of your home, away from the microwave and the cordless phone. A router stuffed in a closet in the basement will never cover the second floor properly.

Step 4: if your home is large or has thick walls (concrete, brick), invest in a mesh system (like TP-Link Deco or Google Nest WiFi). These are 2-3 units that create a uniform network throughout your whole house. It's a relay system — each unit boosts the signal for the next.
