GoKawiilWired 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.
GoKawiil's interpretation of the reporting above, not reported fact.
The guidance suggests many households could get meaningfully faster whole-home Wi-Fi without buying new hardware, simply by running a cable between mesh nodes where feasible. It also implies that shoppers evaluating mesh systems should treat dual-band designs skeptically, since their performance may be compromised by default wireless backhaul.
- Wireless mesh backhauls can lose hundreds of megabits of speed over distance.
- Dual-band mesh systems may share bands between backhaul and devices, hurting both.
- An Ethernet (Cat 6) backhaul can deliver 1 Gbps or more and avoids these bottlenecks.
