Almost every unstable business Wi-Fi network failed on the day it was set up, and almost always for the same seven reasons. They all share the same root — skipping the design — and they can all be avoided with a simple rule: measure before you buy and design before you install. Here are the seven, in the order they usually happen.
The seven mistakes in a business wireless network
- Buying before measuring — the equipment arrives before anyone has studied the building, and the kit defines the network when it should be the other way round.
- Home equipment in an office — supermarket routers and repeaters serving 30 people hold up until the first day the office is full.
- Hidden access point — inside a comms cupboard or on top of the electrical panel "so it can't be seen". The signal can't be seen either.
- Cascading repeaters — every cheap repeater cuts speed and adds instability; three in a chain are a toy network.
- One network for everything — staff, visitors, cameras and printers on the same segment, until the day security depended on them being separate.
- Factory-default channels — access points interfering with each other and with the neighbours, all on the same frequency at the same time.
- Nobody in charge — it was installed, it worked and nobody looked at it again: no updates, no monitoring, no owner.
A network is not bought in boxes: it is designed. The design is what separates "we have Wi-Fi" from "the Wi-Fi works".
