Unstable business Wi-Fi: the 7 design mistakes behind it

A poor wireless network rarely fails by bad luck: it fails the day it is installed. All seven mistakes share one origin, skipping the coverage survey and the design.

Unstable business Wi-Fi costs you every day: interrupted meetings, teams waiting and engineers called in to "see what is going on". Almost always, the problem was born on installation day. Networks that fail repeat the same seven mistakes, and all come from the same source, skipping the design phase. The rule that prevents them is short: measure before you buy, design before you install. Here are the seven, in the order they usually appear.

Which mistakes ruin business Wi-Fi?

  1. Equipment bought without a survey: the boxes arrive before anyone has analysed the building, and the network ends up dictated by the hardware, when it should be the other way round.
  2. Home kit in the office: a retail router and repeaters serving 30 people hold out until the first day the office is full.
  3. Access point out of sight: shut in the comms cupboard or perched on the electrical panel so as not to spoil the décor. The signal ends up as hidden as the equipment.
  4. Repeater after repeater: each hop cuts throughput and adds instability; three in a row is no longer a network, it is a workaround.
  5. Everything on the same segment: staff, guests, cameras and printers together, until the day security needed them apart.
  6. Default channels: access points interfere with each other and with the neighbours, all competing for the same frequency.
  7. A network with no owner: installed, working and then forgotten: no updates, no monitoring, no one accountable.

Wi-Fi is not bought off a shelf: it is designed. Design is what separates "there is Wi-Fi" from "the Wi-Fi works".

Which method eliminates all seven mistakes?
