Step by step
Conduct a baseline speed test
Run a speed test from a device connected via Wi-Fi near your router. If your download and upload speeds match your service provider's plan, your wireless network is currently sufficient for standard tasks.
Note: Use an official ISP speed test tool for the most accurate results.Identify high-bandwidth, latency-sensitive hardware
Catalog devices such as desktop gaming PCs, 4K streaming consoles, and home servers. These devices benefit significantly from the consistent, low-latency path provided by an Ethernet cable.
Evaluate your physical environment
Identify physical obstructions like concrete walls, metal appliances, or mirrors between your router and endpoint devices. If these barriers cause frequent packet loss or signal degradation, physical cabling is the only solution for reliability.
Note: Wireless signals degrade through solid masonry and metal.Review device port availability
Check the back of your primary devices for an RJ45 Ethernet port. If the device lacks a native port, you must account for the cost of a USB-to-Ethernet adapter before proceeding with a wired installation.
Determine the necessity of Ethernet
Prioritize Ethernet for stationary devices requiring high-throughput or real-time responsiveness. Reserve Wi-Fi for mobile devices and IoT peripherals where physical mobility is essential.
Note: Consider powerline adapters if running new cables through walls is not feasible.
