Why does my phone only lose Wi-Fi in one corner of the house?

Your phone loses Wi‑Fi in that one corner because the signal is getting weakened there by distance, walls, and interference. Corners are often the worst spot in a house, especially if the router is far away or behind obstacles.

Common causes

• Thick walls or metal: brick, concrete, plaster, pipes, ductwork, and mirrors can block or reflect Wi‑Fi.
• Band range: 5 GHz and 6 GHz are faster but don’t travel as well through walls; your phone may be clinging to a weak signal.
• Router placement: low, hidden, or off to one side creates dead zones in far corners.
• Interference: microwaves, baby monitors, Bluetooth gear, or a nearby neighbor’s Wi‑Fi can make one area worse.

Best fixes

• Move the router to a central, elevated, open spot.
• Split the network names so you can use 2.4 GHz in weak areas.
• Try a clearer 2.4 GHz channel: 1, 6, or 11.
• If the house layout is the problem, add a mesh Wi‑Fi system.
