Published 22 Feb 2026 · Category: Knowledge · Web: https://level-floor.bnr.la/blog/wifi-explained-24ghz-5ghz-6ghz/ *Your router broadcasts on multiple frequency bands — but what does that actually mean, and which one should your devices connect to? Here is everything explained simply.* > **Note:** Quick answer: 2.4GHz travels further through walls; 5GHz is faster at close range; 6GHz is the fastest but shortest range, available on WiFi 6E and 7 devices only. When you look at your WiFi network list you might see two or three networks from the same router — one labelled 2.4G and one labelled 5G, and increasingly a third labelled 6G. These are different frequency bands , each with its own trade-offs between speed, range, and interference. Understanding the differences helps you get the best performance out of every device in your home — from smart bulbs to gaming consoles to laptops. ## The Three WiFi Bands at a Glance ## 2.4 GHz — The Long-Range Band The 2.4 GHz band has been used since the original 802.11b WiFi standard in 1999. Its long wavelength gives it excellent range and wall penetration — a 2.4 GHz signal can travel through several walls and floors where a 5 GHz signal might struggle. Best for: Smart home devices (lights, plugs, sensors) that just need a basic connection Devices far from the router or access point Older devices that only support 2.4 GHz The downside: The 2.4 GHz band is severely congested. In a typical Australian suburb, your router's 2.4 GHz signal competes with every neighbour's router, all your Bluetooth devices, your microwave oven, and your baby monitor. There are only three non-overlapping channels (1, 6, and 11), meaning routers in nearby homes are almost always stepping on each other's frequencies. ## 5 GHz — The Everyday Workhorse The 5 GHz band is the right choice for most devices most of the time. It offers significantly faster speeds than 2.4 GHz, far less congestion (24 non-overlapping channels), and good range within a room or through a single wall. Best for: Laptops, phones, and tablets Streaming video (Netflix, YouTube, Disney+) Gaming consoles Any device within 15 metres of the access point Modern dual-band routers and access points — including the UniFi U6+ (MPN: U6+) — broadcast both 2.4 GHz and 5 GHz simultaneously. Most will automatically steer your device to the best band using band steering technology. ## 6 GHz — The Future Band (WiFi 6E and WiFi 7) The 6 GHz band was opened for WiFi use in Australia in 2021. It offers a massive 1200 MHz of fresh spectrum — more than the 2.4 GHz and 5 GHz bands combined. This translates to extremely high speeds and virtually zero interference from legacy devices, since only modern WiFi 6E and WiFi 7 devices can use it. Best for: High-bandwidth devices very close to the access point VR headsets, high-resolution video streaming, and fast file transfers Multi-gigabit wireless backhaul in mesh systems The catch: 6 GHz signals are shorter range and struggle with walls more than 5 GHz. Your phone needs to support WiFi 6E or WiFi 7 to connect to it. Most devices sold before 2022 cannot use 6 GHz at all. The Ubiquiti U6-Enterprise (MPN: U6-ENTERPRISE) is a tri-band WiFi 6E access point that broadcasts all three bands simultaneously, with a 2.5 GbE uplink to handle the combined throughput. ## WiFi Standards — 5, 6, 6E, and 7 Explained WiFi standards (the 802.11 family) define maximum speeds and which bands are supported: ## Which Band Should Each Device Use? Here is a practical guide for assigning devices to the right band: Smart home sensors, old printers, IoT devices → 2.4 GHz (they likely only support it anyway) Phones, tablets, laptops in the same room → 5 GHz or 6 GHz if supported Streaming TV sticks and smart TVs → 5 GHz Gaming consoles → 5 GHz, or better yet, a wired Ethernet connection via a network switch Devices far away or through multiple walls → 2.4 GHz or consider adding a second access point If you are on NBN with a 100 Mbps or 250 Mbps plan, even 2.4 GHz is technically fast enough for your internet connection — the real benefit of 5 GHz is lower latency and less interference, not raw internet speed. **Q: Should I connect my devices to 2.4GHz or 5GHz?** A: Use 5 GHz for anything that needs speed — laptops, phones, streaming devices. Use 2.4 GHz for smart home devices or anything far from the router. Most modern routers handle this automatically with band steering. **Q: Why is my 5GHz WiFi slower than 2.4GHz sometimes?** A: This usually means your device is too far from the router or access point. At long range, 5 GHz will drop to a lower data rate than 2.4 GHz to maintain the connection. The fix is adding a second access point closer to the device, or using a wired connection. **Q: Do I need WiFi 6E or WiFi 7?** A: Not urgently. WiFi 6E and 7 are future-proofing — they provide cleaner 6 GHz spectrum and faster speeds for the next generation of devices. If you are buying a new router or access point today, WiFi 6E or 7 is worth paying for. If your current gear works well, there is no urgent reason to upgrade. **Q: Why does my microwave interfere with WiFi?** A: Microwave ovens operate at 2.45 GHz — right in the middle of the 2.4 GHz WiFi band. They leak small amounts of electromagnetic energy that can disrupt nearby WiFi signals. Switching affected devices to 5 GHz solves this immediately. *(2 interactive product/price widget(s) omitted — see the web page for live pricing, or the product .md twins linked from https://level-floor.bnr.la/store/products.md.)* --- More articles: https://level-floor.bnr.la/blog/ · Store: https://level-floor.bnr.la/store/products.md · Index: https://level-floor.bnr.la/llms.txt
