Ceiling Mounted WiFi Extenders: What to Choose and How to Place Them

Only if the manufacturer permits that orientation and the unit can be secured with adequate ventilation and safe power. Many plug-in models are designed for a wall outlet, so check the manual before mounting.

For planned overhead coverage, a ceiling access point with Ethernet backhaul is usually the more suitable design. A wireless extender is easier to add, but its performance depends on the signal it receives from the router.

Place it between the router and the weak-signal area, where it still receives a reliable connection. Avoid hiding it behind furniture or placing it beside sources of interference.

Not by itself. Height can change obstructions and propagation, but the backhaul quality, building materials, interference and client device all affect the result.
