Fiber optic upgrade requires router replacement

You may need a new router to fully benefit from fiber optic speeds, but your existing router can work if it has a compatible Ethernet WAN port and can handle the bandwidth. Router Compatibility with FiberFiber optic internet delivers data via an Optical Network Terminal (ONT), which converts light signals into electrical signals for your router. If your current router has a standard Ethernet WAN port, it can technically connect to the ONT and provide internet access to your home network.

However, the performance you experience depends on the router's capabilities, including its maximum speed, Wi-Fi standard, and ability to handle multiple devices. When a New Router is RecommendedHigh-speed plans: If your fiber plan offers multi-gigabit speeds (2 Gbps or higher), older routers with only Gigabit Ethernet ports will become a bottleneck, limiting your internet performance. Older routers: Routers more than 3–5 years old may not support the latest Wi-Fi standards (like Wi-Fi 7) and could struggle with multiple devices, causing latency or buffering issues.

VoIP integration: Full Fibre broadband often uses VoIP for phone calls. Older phones or routers without VoIP support may require upgrades to ensure smooth operation. Benefits of Using a Provider-Supplied RouterMost ISPs provide a Full Fibre router during installation, which is pre-configured to handle high speeds, multiple devices, and VoIP services.

Using the ISP-provided router ensures optimal performance and compatibility with their network.

Practical Advice

Check if your current router has a Gigabit or multi-gigabit WAN port. Ensure it supports the latest Wi-Fi standards and can handle your household device load. If you experience slow speeds, latency, or connectivity issues after switching to fiber, upgrading to a fiber-compatible router is advisable.

Consider using the router provided by your ISP for seamless integration and support. In summary, while your existing router may work with fiber, upgrading to a modern, fiber-ready router is often necessary to fully utilize the speed, reliability, and features of fiber optic internet.
