Wi-Fi and Home Networking

Separate an internet-plan problem from Wi-Fi coverage, interference, congestion, and one-device faults with a repeatable sequence of tests.

Compare mesh systems, range extenders, and wired access points by backhaul, roaming, placement, setup complexity, and the shape of the home.

Understand how Wi-Fi bands trade range, channel availability, interference, throughput, and device compatibility without treating frequency as speed.

Place a router by measuring the real radio path through rooms, floors, metal, masonry, cabinets, and competing electronics instead of guessing.

Convert megabits into file download time while keeping bits, bytes, decimal and binary units, protocol overhead, and server limits explicit.

Separate a single slow device from coverage, congestion, and an upstream internet fault, and get the next controlled test to run.

Convert file size and Mbps into a realistic download time, with the bits-to-bytes conversion and effective rate both written down.
