A network that works badly gets noticed every day. A well-designed network is never noticed - and that is exactly the point.
The network is the least visible and most structural part of an IT setup. As long as it holds, nobody thinks about it. The moment it falters, everything stops: shared files, the printer, the till, the business software, video calls. It is also the part most often improvised for lack of time, and the one that ends up being redone.
We start by understanding what will travel across this network. That is not a formality: a practice opening large files from a server does not have the same needs as a shop with a till and two machines.
The questions that determine everything else: how many devices are genuinely connected, counting the phones, the TVs and the connected objects everyone forgets. Where the fixed machines are, and which ones move. Which uses are critical and cannot stop. And what the building is like - an open-plan floor, an older building with thick walls, or a house on three levels are not treated the same way.
It is the advice that surprises people most, and it is the most useful. For a desktop machine, a server, a printer or a TV that never moves, a cable is unbeatable: maximum speed, minimum latency, no interference, no settings. A discreet cable along a skirting board often solves in an hour what a wireless device costing several hundred euros will never fully fix. We always propose this solution where it can be done.
The operator's router. It acts as router, switch, Wi-Fi access point and firewall, with decent performance for home use and quickly limited beyond that. On a business setup, it becomes the bottleneck as soon as the number of devices grows.
The right approach is often to confine it to its role as internet access and leave the rest to dedicated equipment. It costs little and changes a great deal, particularly for stability.
The requests are mostly about coverage in the home: rooms with no signal, speed collapsing upstairs, working from home impossible in the bedroom. The answer depends entirely on the building, and we measure before proposing anything. See our article on Wi-Fi that does not reach upstairs.
To that are often added sharing a printer, reaching photos from the TV, and setting up a central backup.
The stakes shift toward reliability and separating uses. A well-designed business network distinguishes what should see what: workstations on one side, Wi-Fi open to visitors on the other, connected equipment - cameras, till, various devices - in its own space. That separation costs a few minutes of configuration and stops a compromised device reaching your data. See securing a business network.
A plan of what has been installed, the addresses of the equipment, the administration passwords, and which socket goes where. Without that document, the smallest change two years later becomes an investigation. It belongs to you, and it is written to be usable by any technician.
We also work on networks already in place, often built up over time by several people. The diagnosis covers the same points: consistency of addresses, duplicate equipment, unused cables, forgotten remote access, factory passwords never changed. It is rare for everything to be clean, and it is rare that everything has to be redone - most often, a few targeted corrections are enough.
Lyon and its metropolitan area, plus the whole Rhône. The full list of towns is on our towns we cover page.
Not always. Existing conduits, skirting boards and powerline adapters often avoid building work. We look at what can be done before proposing anything.
For simple home use, yes. As soon as there are several work machines, a server or a lot of connected devices, it becomes limiting and is better confined to internet access.
From half a day for a home to several days for business premises with cabling. The quote states the duration after a site visit.
Yes, and it is common. We start with a review: it is rare that everything has to be redone, a few targeted corrections are often enough.
