The 7 most common design mistakes and the method that eliminates them. No-obligation proposal. # Unstable business Wi-Fi: the 7 design mistakes behind it At a glance For decision-makers short on time. - 01 Almost every unstable business Wi-Fi network failed on installation day. - 02 The 7 mistakes share one origin: skipping the coverage survey and the design. - 03 Measure, design, install and manage eliminates all seven. - 04 DataRoad manages 1321 Ubiquiti devices across more than 138 sites. ### In this article **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? - **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. - **Home kit in the office**: a retail router and repeaters serving 30 people hold out until the first day the office is full. - **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. - **Repeater after repeater**: each hop cuts throughput and adds instability; three in a row is no longer a network, it is a workaround. - **Everything on the same segment**: staff, guests, cameras and printers together, until the day security needed them apart. - **Default channels**: access points interfere with each other and with the neighbours, all competing for the same frequency. - **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? | Phase | Work | Mistakes solved | | --- | --- | --- | | Measurement | [Coverage survey](https://www.dataroad-it.com/en/unstable-business-wifi-coverage-study/) carried out in the space as it really is | 1, 3 | | Design | Network sized for the people and devices that actually exist, with segmentation and a channel plan | 4, 5, 6 | | Installation | Professional equipment, placed where it should be | 2, 3 | | Management | Monitoring, updates and a named owner | 7 | ## Is your network already suffering from these mistakes?
