Office network setup: a practical checklist for growing businesses

Nobody notices a good network. Everybody notices a bad one: dropped video calls, slow file transfers, printers that disappear. Whether you're moving into a new office or fixing an existing one, plan the network as carefully as any other business system.

Before anything is installed

• Count devices, not just people. Laptops, phones, printers, cameras, access control, TVs, IoT sensors: each one needs a connection and an address.
• Map the space. Note walls, floors and materials that block wireless signals, and where people actually sit and meet.
• Plan for growth. Allow spare capacity in switches, cabling and internet bandwidth for the next few years, not just today.

Cabling and hardware

• Use structured, labelled cabling to fixed desks, meeting rooms and wireless access points. Wired connections are faster and more reliable than wireless for anything stationary.
• Choose business-grade switches and access points that can be managed centrally and updated.
• Put the core equipment in a ventilated, secure location with power protection (UPS).

Wireless done properly

• Place access points from a site survey, not guesswork. Coverage and capacity both matter in busy rooms.
• Separate networks for staff, guests and devices (cameras, printers, IoT), so a guest or a cheap gadget can't reach company data.

Security

• Change every default password. Keep firmware updated.
• Use a firewall, and enable VPN access for remote work instead of exposing internal services to the internet.
• Give each person their own credentials, and remove access promptly when someone leaves.

Resilience

• Consider a second internet connection or a mobile backup if downtime would stop the business.
• Back up important data automatically, keep a copy off-site, and test restoring it.

Documentation

Keep an up-to-date record of the network layout, equipment, IP ranges, passwords (in a password manager) and support contacts. It turns every future problem or upgrade from guesswork into a quick job.
