What WiFi router do I need for my home?
Short answer
For a flat or a small house, a dual-band router is enough. For a large house, two storeys or thick walls, a mesh system of several nodes beats a single router, because there the problem isn't power but coverage. And if you use the router your provider left you, replacing it usually improves the signal noticeably.
Choosing a router is complicated because the boxes are full of huge numbers that barely matter. The real decision is simpler and comes down to one thing: the problem you have. Is it speed or coverage? The answer changes everything.
First, identify your problem
- “WiFi is slow where I’m sitting” → a speed problem. A good router solves it.
- “There are rooms where WiFi doesn’t reach or cuts out” → a coverage problem. No single router fixes it. You need mesh.
Confusing the two is the most common mistake: buying the most expensive router to solve a coverage problem, and still having no signal at the back of the house.
Dual-band: today’s minimum
A dual-band router broadcasts on two frequencies:
- 2.4 GHz — reaches further and through walls, but slower and more congested.
- 5 GHz — much faster, but shorter range.
Each device connects to whichever suits it. It’s the minimum worth buying today; single-band ones are outdated.
WiFi 6: matters for quantity, not speed
WiFi 6 doesn’t make a single device faster. What it does well is handle many devices at once without them clashing.
- Home with 3-4 connected things → a good WiFi 5 is enough.
- Home with 10-15 things (phones, TVs, cameras, smart bulbs, robot) → WiFi 6 shows.
If you’re upgrading and the price gap is small, get it. Otherwise it isn’t urgent.
Router or mesh
| Your home | What to buy |
|---|---|
| Flat, small space | Dual-band router |
| Large, two-storey, long house | Mesh system (several nodes) |
| Thick masonry walls | Mesh |
Mesh is several nodes spread around creating one network: the device hands off from the nearest to the next without you noticing. It’s the only real solution to a coverage problem.
Replace the provider’s router
It’s one of the cheapest improvements for your internet. ISP routers are the most basic possible. A mid-range one of your own almost always gives better range and stability.
A technical detail: the provider’s device is often a combined modem-router. If you replace it, put it in bridge mode so it only acts as a modem and your new router handles the WiFi. That step sometimes means calling support.
Frequently asked
What is dual-band and what's it for?
A dual-band router broadcasts on two frequencies at once: 2.4 GHz and 5 GHz. The 2.4 GHz reaches further and passes through walls better, but is slower and more congested because many devices in the neighbourhood use it. The 5 GHz is much faster but has shorter range. The point of dual-band is that each device connects to whichever suits it: the phone at the back of the house to 2.4 GHz, the smart TV next to the router to 5 GHz for 4K without buffering. It's the minimum worth buying today; single-band routers are outdated.
Is a WiFi 6 router worth it?
It depends on how many devices you have connected at once, more than on your internet speed. WiFi 6 (also called 802.11ax) doesn't make a single device much faster; what it does well is handle many simultaneous devices without them clashing. In a home with two phones, a laptop and a smart TV, a good WiFi 5 router works perfectly. In one with ten or fifteen connected things — several phones, TVs, speakers, cameras, robot vacuum, smart bulbs — WiFi 6 shows. If you're upgrading and the price difference is small, get it; otherwise it isn't urgent.
Regular router or mesh system?
The right question isn't which is better but what problem you have. If your problem is speed in a space where the signal reaches, a good router solves it. If your problem is coverage — there are rooms where the WiFi doesn't reach or is weak — no router, however powerful, will fix it, because the signal hits the walls and the distance. There the solution is a mesh system: several nodes spread around the house creating a single network, and the device hands off from the nearest to the next without you noticing. For a flat, a router. For a large, two-storey or long house, mesh.
Should I replace the router my provider gave me?
In most cases, yes, and it's one of the cheapest improvements you can make to your internet. The routers ISPs leave tend to be the most basic possible: they cover the bare minimum and prioritise cost. A mid-range router of your own almost always gives better range, more stability and better handling of multiple devices. Watch one detail: in many cases the provider's device is actually a combined modem-router, so if you replace it you have to put it in bridge mode so it only acts as a modem and your new router handles the WiFi. It's a configuration step that sometimes means calling support.
