New routers and phones advertise Wi-Fi 6, 6E and 7. Meanwhile, your Wi-Fi still drops in the bedroom. Understanding what each version actually changes, and where most slowdowns really come from, saves you money and frustration.
The versions in plain words
| Name | Standard | What it adds |
|---|---|---|
| Wi-Fi 5 | 802.11ac | Fast 5 GHz connections; still common |
| Wi-Fi 6 | 802.11ax | Handles many devices at once much better; more efficient on battery |
| Wi-Fi 6E | 802.11ax in 6 GHz | Adds the 6 GHz band: wide, uncrowded channels for nearby devices |
| Wi-Fi 7 | 802.11be | Wider channels and multi-link operation, using several bands at once |
Whether the 6 GHz band can be used depends on each country's spectrum rules. Check that both your router and your country support it before paying extra.
Why faster Wi-Fi does not mean faster internet
Wi-Fi only connects your devices to your router. If your internet plan is 100 Mbps, a Wi-Fi 7 router will not make websites load at 1,000 Mbps. Upgrading helps most when you have a fast fibre plan, many devices, or large files moving within your home.
2.4 GHz vs 5 GHz vs 6 GHz
Lower frequencies travel farther and through walls better but are slower and more crowded. Higher frequencies are faster but weaker through walls. Modern routers steer devices between bands automatically.
How to fix slow Wi-Fi (in order)
- Move the router to a central, raised, open spot. Not inside a cabinet or behind the TV.
- Restart the router and update its firmware.
- Use 5 GHz for devices near the router.
- Change the channel if your neighbours' networks crowd yours.
- Use a mesh system for large or multi-floor homes instead of a single powerful router or cheap repeaters.
- Use an Ethernet cable for the TV, gaming console or work computer.
- Check your plan's speed with a wired connection to see if the problem is the internet itself.
Frequently asked questions
Do I need a Wi-Fi 7 router?
Only if you have fast fibre internet and Wi-Fi 7 devices. Otherwise, a good Wi-Fi 6 router or mesh system is excellent value.
Does reinforced concrete block Wi-Fi?
Yes. Concrete walls, steel and mirrors weaken signals considerably, which is why multi-room homes in India often need a mesh system.
