Router marketing is full of big numbers and confusing names: AX5400, BE19000, tri-band, mesh. This guide explains what actually matters so you can pick a router that suits your home and devices. It compares technologies and published specifications rather than reviewing individual products.

Step 1: Understand the Wi-Fi standards

Name Technical name Bands Key features
Wi-Fi 5 802.11ac 5 GHz (with 2.4 GHz via older standard) Older but still common
Wi-Fi 6 802.11ax 2.4 GHz and 5 GHz Better performance with many devices (OFDMA), target wake time for battery saving, WPA3 required for certification
Wi-Fi 6E 802.11ax Adds 6 GHz Extra, less-congested spectrum for compatible devices
Wi-Fi 7 802.11be 2.4, 5 and 6 GHz Wider 320 MHz channels in 6 GHz, Multi-Link Operation (MLO) using several bands at once, higher peak speeds

Routers are backwards compatible, so older devices still connect – they just use the older standard’s capabilities.

Your devices matter as much as the router. A Wi-Fi 7 router won’t make a Wi-Fi 5 laptop faster than Wi-Fi 5 allows. Check what your phones, laptops and TVs support.

Availability of the 6 GHz band and allowed power levels vary by country, so check that 6E or 7 features are supported where you live.

Step 2: Decode the speed numbers

A router labelled AX5400 or BE9300 is advertising the combined theoretical maximum of all its bands added together. No single device will ever reach that figure – a typical phone or laptop connects to one band with a limited number of antennas. Use these numbers to compare models within the same family, not as a promise of real-world speed.

What matters more in practice:

  • whether it supports the bands your devices use;
  • coverage in your particular home;
  • the number of devices it can handle well;
  • software quality, updates and security.

Step 3: Single router or mesh?

  • Single router: fine for flats and smaller homes where the router can be placed centrally.
  • Mesh system: two or more units that work together as one network, ideal for larger homes, multiple floors, thick walls or long, narrow layouts.
  • Wired backhaul: if you can connect mesh units to each other with Ethernet cables, performance improves significantly. Look for mesh units with Ethernet ports.
  • Tri-band mesh: some mesh systems use an extra band dedicated to communication between units, which helps when there’s no wired backhaul.

Step 4: Check ports and wired features

  • WAN port speed: if your broadband plan is faster than 1 Gbps, you need a router with a multi-gig WAN port (2.5 Gbps or more).
  • LAN ports: enough Ethernet ports for desktops, consoles, TVs and network storage – and multi-gig LAN ports if you need fast local transfers.
  • USB port: some routers can share a printer or drive, though dedicated network storage is usually better.

Step 5: Prioritise security and updates

A router is the front door of your network. Look for:

  • WPA3 support (with WPA2/WPA3 mixed mode for older devices);
  • automatic firmware updates, and a manufacturer with a clear record of providing security updates for several years;
  • the ability to change the admin password (and no fixed default passwords);
  • a guest network to keep visitors and smart home devices separate from your main devices;
  • the option to disable remote management and WPS if you don’t need them.

When a router stops receiving security updates, it’s time to replace it.

Step 6: Consider useful extras

  • Parental controls and scheduling.
  • Quality of Service (QoS) to prioritise video calls or gaming.
  • An easy app for setup and monitoring.
  • VPN server or client features for advanced users.
  • Subscriptions: some features (advanced security, parental controls) require a paid subscription – check what’s included without one.

Quick recommendations by situation

  • Small flat, few devices: a quality Wi-Fi 6 router is usually plenty.
  • Family home with many devices: Wi-Fi 6 or 6E; consider mesh for multiple floors.
  • Large or multi-storey home: a mesh system, ideally with wired backhaul.
  • Latest phones and laptops, very fast broadband: Wi-Fi 6E or Wi-Fi 7 with a multi-gig WAN port.
  • Small office: look for business-oriented features such as VLANs, multiple SSIDs, reliable updates, and consider professional access points.

Conclusion

Choose a router based on your home’s size, your devices and your broadband speed rather than the biggest number on the box. Wi-Fi 6 is a solid baseline, 6E and 7 add capacity for newer devices, and mesh solves coverage problems in larger homes. Above all, pick a manufacturer that provides regular security updates.

Frequently asked questions

Will a new router make my internet faster?
It can make Wi-Fi faster and more reliable inside your home, but it can't exceed the speed of your broadband plan. If your wired speed test is already slow, the bottleneck is your internet connection, not the router.
Do I need Wi-Fi 7?
Only if you have, or plan to buy, devices that support it and you want the highest possible speeds. For most homes, a good Wi-Fi 6 or 6E router provides plenty of performance. Wi-Fi 7 routers are backwards compatible, so they also work with older devices.
Should I use my internet provider's router?
Provider routers have improved and are convenient, and some services need them for features like phone lines. If coverage or features are lacking, you can often add your own router or mesh system – check your provider's instructions for using third-party equipment.
