Home networking is the part of consumer technology where people most often blame themselves for a problem the equipment caused. Kim Tran writes the Networks section on that premise. It covers what each Wi-Fi standard changed and what it did not, why a mesh system sometimes performs worse than the router it replaced, how interference behaves in an ordinary home with ordinary walls, and what the numbers on the box mean once protocol overhead is accounted for. The habit here is to carry a claimed figure through to a realistic result and show the arithmetic, so the distance between marketing and observation is visible rather than asserted.
