Most modern routers create two Wi-Fi networks, often with names like “Home” and “Home_5G”. They are two different radio bands, and each has its own strengths. Using the right one can make a noticeable difference to your speed.
2.4 GHz: longer range, lower speed
- Travels further and passes through walls better.
- Slower top speed.
- More crowded, because neighbours’ routers, Bluetooth devices and microwave ovens all use it.
Best for: smart plugs, CCTV cameras, printers and devices far from the router.
5 GHz: higher speed, shorter range
- Much faster, often several times quicker than 2.4 GHz in the same room.
- Less interference, so it is more stable.
- Weaker through walls and over long distances.
Best for: smart TVs, laptops, phones and gaming consoles in the same room or the next room.
How to choose
- If you are close to the router and your device supports it, use 5 GHz.
- If you are two or more rooms away and 5 GHz keeps dropping, switch to 2.4 GHz.
- Connect devices that do not move, like a smart TV, to the band that gives the best speed test result in that spot.
Does my device support 5 GHz?
Most phones and laptops from the last few years do. If you cannot see the 5G network in the Wi-Fi list, your device probably supports only 2.4 GHz. Some very cheap smart devices also only work on 2.4 GHz.
One name or two?
Some routers can show both bands under one name and move devices automatically (“band steering”). This is convenient, but some devices stick to the slower band. If you notice this, separate the names so you can choose yourself.
