Even the best mesh Wi-Fi system can be easily improved with a simple cable. While mesh networks eliminate dead zones and provide consistent speeds, their performance is often limited by wireless backhaul—the connection between routers. By default, mesh systems use Wi-Fi to communicate between nodes, which can reduce speeds over distance and create bottlenecks, especially in dual-band models.
Switching to an Ethernet backhaul solves both issues, delivering near-gigabit speeds and freeing up bandwidth for devices. Using Cat 6 cables ensures minimal speed loss, and while running wires across a home may be impractical for some, the performance gains are significant for those willing to invest in cabling or an Ethernet switch.
