Wi-Fi coverage guides

62 plain-English guides on dead zones, extender and mesh placement, awkward floor plans and the rooms that never get signal.

Range or speed, room by room — plus band steering, split names and extender backhaul.

Microwaves, monitors, USB 3 docks, neighbors. A 60-second on-off test names the culprit.

Honest indoor radii by band and construction, plus the arithmetic that gives you your own number.

A phone walk test, a spreadsheet grid, or a simulated floor plan — and which one answers your question.

Bars only report loudness. The five numbers that decide real speed, and why one old device slows everyone.

Newer standards buy capacity, not reach. What genuinely improves, and what still needs a second radio.

Full bars in the far room and nothing loads? The extender is probably out past its own backhaul.

What really decides powerline speed, when it beats a repeater, and the hybrid setup for detached rooms.

Reuse existing coax, run one cable, and turn a spare router into a real access point.

Two extenders on separate legs is fine. Chaining one off the other costs half your speed per hop.

Floor outlets cost 3 to 8 dB. What ankle level does to signal, and safe ways to lift the unit.

One name is the default. Here are the four cases where a second network name is the honest fix.
