Getting the Most Out of Your Wi-Fi

Extra tips to help you get the
best home internet experience

This page aims to help you understand how your devices affect speed, which Wi-Fi band to use, the difference between dual-band and tri-band routers, and when it’s worth using a wired Ethernet connection instead.

Are your devices holding you back?

Even if your router is well-equipped to support your internet plan, your device could still be the bottleneck. Older Wi-Fi standards like Wi-Fi 4 or 5, or even limited hardware on newer standards can cap your speeds.
That’s why it’s worth checking your device manufacturer’s specs to see what maximum Wi-Fi speeds it supports.

Tip
Tip: To accurately test your speed, use a device that supports your plan’s speeds on Wi-Fi or connect directly via a wired Ethernet connection.

Understanding Wi-Fi bands

Most routers support 2.4GHz and 5GHz frequency bands (or “channels”), while newer Tri-Band routers may also offer 6GHz support. These are the frequencies your Wi-Fi signal uses. 

Here’s how they impact your performance:

Band Best for Trade-offs
2.4GHz Greater coverage, basic web browsing and low-bandwidth tasks Slower speeds, susceptible to more interference
5GHz Streaming, gaming, and video calls Faster, but with a shorter range
6GHz Fastest frequency band with lower latency; ideal for gaming and 4K streaming Requires Wi-Fi 6E/7, and has a limited range

  • 5GHz or 6GHz is ideal for high-performance use cases, but only if you’re within a shorter range.
  • 2.4GHz has broader coverage but is more prone to interference from other devices (microwaves, baby monitors, etc.). This interference could actually impact the coverage, so it’s worth testing each frequency band to see what works best for you.
Tip
Tip: If your device or router allows it, manually choosing the right band can improve your range or Wi-Fi speed and stability depending on the frequency you select.

Dual-band vs tri-band routers:
What’s the difference?

A dual-band router has two frequencies (2.4GHz and 5GHz), while a tri-band router adds an additional 5GHz or 6GHz band.  

  • Tri-band routers can split traffic more efficiently across multiple devices.
  • In busy households, this can prevent slowdowns from too many devices competing for bandwidth.
  • In mesh setups, the extra band is often used as a dedicated “backhaul” — keeping node-to-node traffic separate from your devices.
Tip
Tip: If you live in a large household, with many heavy internet users and connected devices, a tri-band router such as the eero Pro 7 may be worth the upgrade.

Using a wired connection vs Wi-Fi

Wi-Fi’s great for flexibility, but if you’re gaming, working, or streaming in 4K, connecting your device to your router via an Ethernet cable will give you the fastest, most reliable experience possible.

Different types of Ethernet cables exist, but it’s recommended to use at least CAT 6 cables to ensure you achieve the full speeds of your internet plan, particularly if you have a multi-gig connection.

Ethernet Cable Categories Supported Cable Speeds at Maximum Cable Distance
CAT 6a Up to 10Gbps to 100 metres
CAT 6 Up to 5Gbps to 100 metres
CAT 5e Up to 1Gbps to 100 metres
CAT 5 Up to 100Mbps

If you’re using a mesh Wi-Fi system, connecting your mesh units together via Ethernet can also significantly improve performance and stability, especially in larger homes.
