A Wi-Fi mesh network has been optimized to eliminate poor coverage areas, yet users still...

Relocate any large, dense, solid, and metal objects, such as mirrors and file cabinets, in the mesh network coverage area to the perimeter so that wireless reflections, absorptions, and occlusions are minimized.

Use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.

Use the signal strength indicator on a mobile device to roam the coverage area and generate a heat map to isolate zones with weak signals.

Turn off broadcasting of the SSID on the mesh network so that other networks cannot see it.
