After extensive trials and configurations, I’m thrilled to share my journey in optimizing my Nest WiFi Pro setup. Initially, I faced significant challenges with device limitations, especially in a large house with a semi-separate apartment. My goal was to ensure reliable internet coverage for both myself and my tenant, who required fast speeds for home office work.I started with a mesh-only setup, purchasing 11 access points, only to discover that performance deteriorated after the fifth device. This led me to explore wired backhaul solutions. My setup involved a fiber optic connection to a modem, connected to the main Nest WiFi router, which was then linked to a switch (TP-Link TL-SG116). From there, I connected multiple devices, including a Hue Bridge, PCs, printers, and additional Nest WiFi access points.The breakthrough came when I realized that wired backhaul could overcome the 5-device limitation. By strategically placing access points and ensuring a wired connection from the switch to the apartment’s access point, I managed to achieve consistent performance. However, I encountered issues with network speed drops and double NAT, which required careful configuration to resolve.Through persistent experimentation and fine-tuning, I successfully implemented a second mesh network in the apartment without compromising overall performance. This setup now provides seamless coverage throughout the house, with speeds restored to optimal levels. The wired backhaul proved crucial in maintaining stability and avoiding the pitfalls of wireless-only extensions.This experience taught me the importance of a well-planned network architecture and the value of wired connections in overcoming device limitations. It also highlighted the need for thorough research and troubleshooting to resolve complex issues.If anyone else is tackling similar challenges, I encourage you to explore wired solutions and meticulous configuration. It’s a rewarding process that can transform your smart home setup. Feel free to reach out if you have questions or need advice—I’m happy to help!
