How to Choose a Wi-Fi Router: Wi-Fi 6, 6E and 7 Explained
Understand Wi-Fi standards, bands, mesh systems and security features so you can choose the right router for your home or small office – without paying for features you won't use.

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.
