Wired Ethernet backhaul outperforms wireless on mesh Wi-Fi systems
Mesh Wi-Fi systems normally link their routers wirelessly through a 'backhaul' connection that shuttles data between nodes, which can lose speed over distance and, on cheaper dual-band models, compete with devices for the same wireless bands. Replacing that wireless link with an Ethernet cable, ideally Cat 6, removes both problems, delivering around 1 Gbps or more between nodes regardless of band limitations.
