We have generally been impressed by the range and throughput potential of Mesh WiFi systems (https://www.kitguru.net/peripherals/james-morris/ultimate-mesh-wifi-router-shootout/) . But these either require you to turn off your existing WiFi or replace your original router entirely, which is a waste of money if you only just bought it. If you replace your router entirely, you will also be locked into the features available from the mesh kit, which may be limited for some routers. But what if you could get a mesh system using your existing router’s WiFi? This is the basic theory behind ASUS’s AiMesh.
