How to Choose the Best Router for Your Lit Fibre Only Connection

Any modern router with at least a 1 Gbps WAN port, WiFi 6 and Gigabit LAN ports will work with a Lit Fibre connection.
If you have Lit2400, we recommend a router with 2.5 Gbps WAN/LAN ports and ideally WiFi 7 to unlock the full performance of your package.

When you choose a Lit Fibre Only package, you’re free to pick the router that best suits your home. We bring full-fibre directly into your property, and you choose the hardware that helps your devices perform at their best.
This guide highlights the features that matter most.


What WAN port does my router need for a Lit Fibre connection?

Your router must have a Gigabit WAN port as a minimum, or a 2.5 Gbps WAN port if you are on Lit2400.
The WAN port is the connection between your router and the Lit Fibre ONT (the fibre connection point in your home).

What to look for:

  • Minimum: 1 Gbps WAN port

  • For Lit2400: 2.5 Gbps or faster WAN port

  • Avoid older routers that only support 100 Mbps, as they will bottleneck your full-fibre speeds

  • Use a Cat 6 Ethernet cable when connecting your router to the ONT

A fast WAN port ensures you can make full use of your package’s speed.


What LAN ports do I need for my wired devices on Lit Fibre?

Choose a router with at least Gigabit LAN ports for smooth, reliable wired performance.
LAN ports are used for devices you connect by cable, such as smart TVs, gaming consoles and desktop computers.

Recommended features:

  • Gigabit LAN ports as standard

  • Additional ports if you plan to connect several devices

  • Multi-gig LAN ports (2.5 Gbps+) on premium routers for future-proofing

Wired connections offer excellent stability — perfect for gaming, 4K streaming or home working.


What WiFi features should my router have for Lit Fibre?

Choose a router with WiFi 6 or newer for fast, efficient wireless coverage throughout your home.

For strong, consistent WiFi, we recommend:

  • WiFi 6 (802.11ax) or newer

  • Tri-band WiFi in busy homes or for many devices

  • High-gain or external antennas if your home is large or has thick walls

  • A central, elevated placement for the strongest signal

If you live in a larger property, a mesh WiFi system helps extend coverage into every room.

Quick Tip:
If your WiFi feels slower than expected, check whether your router, cables and device support the full speed of your Lit Fibre package. A simple hardware update can make a noticeable difference.


Do I need to worry about firewall throughput with Lit Fibre?

If you use advanced security features (such as IPS or deep packet inspection), ensure your router’s firewall throughput can match your package speed.

Some routers slow down when enhanced security features are enabled. If you rely on these tools, check the manufacturer’s performance specifications before choosing a model.
