Fiber and communications infrastructure knowledge brief Published 19 Nov 2024

Use this reference to prepare product questions for BAGYOU FIBRE. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Using a 100Mbps router with gigabit fiber optic internet will limit your connection to 100Mbps, preventing you from fully utilizing the high-speed fiber service.

Understanding the Bottleneck

Fiber optic cables can support gigabit speeds (1 Gbps) or higher, offering extremely fast and stable internet with low latency and minimal interference. However, if your router only supports 100Mbps Ethernet ports or older Wi-Fi standards, it becomes a bottleneck, capping your maximum speed at 100Mbps regardless of your fiber plan. This means downloads, streaming, gaming, and multiple device usage will not reach the potential speeds of your fiber connection.

Router Requirements for Fiber

To fully leverage gigabit fiber, your router should have: Gigabit Ethernet ports (1 Gbps or higher) for wired connections.

Modern Wi-

Fi standards such as Wi-Fi 5 (802. 11ac), Wi-Fi 6 (802. 11ax), or Wi-Fi 7 for wireless devices.

Sufficient CPU and RA

M to handle multiple devices and high throughput without slowing down. Advanced features like MU-MIMO, QoS, and mesh support for large homes or offices. Routers like the NETGEAR Nighthawk RS700S Wi-Fi 7 or ASUS AX6000 Wi-Fi 6 are designed to handle gigabit fiber speeds, multiple devices, and high-bandwidth applications such as 4K/8K streaming, gaming, and video conferencing.

Practical Implications

Wired connections: If you connect a device via a 100Mbps router port, your speed will max out at 100Mbps even if your fiber plan is 1 Gbps. Wireless connections: Older Wi-Fi standards may further reduce speed due to protocol limitations. Multiple devices: A 100Mbps router may struggle with simultaneous connections, causing lag or buffering.

Recommendation

If you have a gigabit fiber plan, upgrading to a router with gigabit ports and modern Wi-Fi standards is essential to fully utilize your internet speed. Even budget-friendly fiber routers like the UFiber UF-WiFi6 provide reliable Wi-Fi 6 performance and gigabit LAN ports for everyday use. For high-performance needs, consider routers with Wi-Fi 6/7, multiple gigabit LAN ports, and mesh capabilities to ensure consistent speed across all devices.

In summary, a 100Mbps router will significantly limit your fiber internet performance, and upgrading to a gigabit-capable router is necessary to take full advantage of your fiber optic connection.
