Office network checklist: what a reliable business network needs

Most office network problems are not caused by the internet provider. They come from a network that was never planned: a router in a cupboard, cables run in a hurry and Wi-Fi that does not reach the back rooms. Use this office network checklist when you set up a new office or review an old one. It also gives you the questions to ask any installer.

1. Plan for people and devices

Count how many people will work in the office, and how many devices each person uses: computers, phones, printers, and later cameras, door readers and IP phones. Add some room for growth. A network sized for exactly today's staff is usually too small within a year.

2. Start with good cabling

• Use quality Cat6 cable and proper connectors. See network cables and connectors.
• Run cables to wall points and terminate them on a patch panel in a rack or cabinet, instead of long loose leads across the floor.
• Label both ends of every cable. It saves hours when something needs to be fixed.
• Keep data cables away from heavy power cables.

3. Choose the right switches

A switch connects your wired devices. Managed switches let you split the network into separate sections (VLANs), see what is happening and set priorities, which matters in larger offices. PoE switches power devices such as IP phones, cameras and Wi-Fi access points through the network cable, so each needs only one cable.

4. Use a proper router and firewall

The router connects you to the internet, and the firewall decides what may come in. A business-grade router or firewall gives you better control and security than a basic home router. Make sure it can handle your internet speed and the number of users.

5. Plan Wi-Fi properly

• Several access points placed around the office work better than one strong router at the front.
• Walls and floors weaken the signal, so placement matters more than power.
• Give visitors a separate guest Wi-Fi that cannot reach your files or printers.
• Keep fixed devices such as desktop computers on cable and leave Wi-Fi for phones and laptops.

6. Add a backup internet connection

If the internet is essential to your business, a second connection from a different provider, with automatic switching, keeps you working when one link fails.

7. Protect the network from power cuts

Put the router, firewall, main switch and any recorder or server on a UPS. A network that restarts cleanly after a power cut saves a lot of calls to support.

8. Cover the security basics

• Change every default admin password, and use a different one for each device
• Keep router, switch and access point firmware up to date
• Back up important files to a second place, not only the same computer
• Remove accounts and Wi-Fi access of staff who have left

9. Document and monitor

Ask for a simple diagram of the network, a list of devices with their addresses and the admin details stored safely. Monitoring tools can warn you about a failing link or a full disk before your staff notice.

Questions to ask your installer

• Will you survey the building before quoting?
• Which cable and equipment will you use, and what warranty do they carry?
• How many users and devices is the design planned for?
• What happens during a power cut or an internet failure?
• Will I receive a network diagram and passwords in writing?
• Who do I call when something stops working?
