A 100m fiber optic wireless router is very slow

Slow speeds on a 100 Mbps fiber optic router are often caused by router limitations, cable issues, network congestion, or configuration settings.Common Causes1. Router Limitations: Older routers may not support full fiber speeds or multiple devices simultaneously. Some routers are limited to 100 Mbps on LAN/Wi-Fi ports even if your fiber plan is faster . 2. Cable Quality: Using outdated or damaged Ethernet cables (Cat 5 or lower) can cap speeds at 100 Mbps. For gigabit speeds, Cat 6 or higher cables are recommended . 3. Network Congestion: Multiple devices streaming, gaming, or downloading simultaneously can reduce available bandwidth for each device . 4. Router Settings: Incorrect WAN/LAN port speed settings, Quality of Service (QoS), or parental controls can throttle speeds. Some routers default to 100 Mbps instead of 1 Gbps . 5. Wireless Interference: Wi-Fi signals can be weakened by distance, walls, or interference from other electronics. 2.4 GHz networks are slower and more prone to interference than 5 GHz networks .Solutions1. Test Direct Connection: Connect a device directly to the fiber modem using a Cat 6 cable to verify your actual internet speed. If speeds are normal, the router is likely the bottleneck . 2. Update Router Firmware: Ensure your router firmware is up to date to fix bugs and improve performance . 3. Adjust Router Settings:Set WAN/LAN ports to 1 Gbps if supported.Disable QoS or parental controls temporarily to see if speed improves .Change Wi-Fi channel and width to reduce interference. 4. Optimize Placement: Place the router in a central, elevated location, away from thick walls and electronic devices . 5. Restart Devices: Power cycle your modem and router to clear temporary glitches . 6. Consider Upgrading Hardware: If your router is older or only supports 100 Mbps, upgrading to a gigabit-capable router will allow you to fully utilize your fiber connection . By systematically checking cables, router settings, and network congestion, you can identify the bottleneck and restore your fiber internet to its expected speed.
