Networking for a small office: routers, switches and cabling

Slow or patchy internet in an office is more than an annoyance — it stalls calls, billing and every cloud tool the team depends on. Most small-office network problems come from a setup that grew piece by piece: a home router, a few extra devices plugged in, Wi-Fi that does not reach the back cabin. Planning it once, properly, avoids years of daily friction.

Start with how the office uses the network

List what depends on it:

• Number of people, laptops and phones on Wi-Fi at the same time
• Video calls, cloud software, large file transfers
• CCTV recorders, biometric attendance, printers and billing machines
• Any server or storage device in the office

This decides the size of the internet plan, the router and the switches.

The internet connection

• Ask your internet provider about the speed actually delivered, not just the plan name, and whether the plan has any usage cap.
• For businesses that cannot go offline, a second connection from a different provider with automatic failover is worth considering.
• A static IP may be needed if you run remote access to CCTV or servers.

Router and firewall

A business-grade router or firewall handles more users, supports separate networks and gives better control.

• Ask for separate networks for staff and guests so visitors do not reach your printers and files.
• Ask about basic security features and whether the vendor will set strong admin passwords and keep firmware updated.

Switches and wired points

Desks with fixed computers, printers and CCTV recorders work better on wired connections.

• Count wired points needed now and add spare ports for growth.
• PoE (Power over Ethernet) switches can power IP cameras and Wi-Fi access points through the network cable, saving separate power points.

Wi-Fi coverage

One router in a corner rarely covers a whole office, especially with walls and cabins.

1. Ask for access points placed for coverage, managed as one network so devices roam smoothly.
2. Ask the vendor to check coverage in every cabin and meeting room after installation.

Cabling and the rack

• Structured cabling — cables run neatly to a central rack, each point labelled — makes future changes and fault-finding far easier.
• Ask what category of cable is being used and whether points will be tested.
• A small wall-mounted rack keeps the router, switches and patch panel safe and tidy.

Mistakes to avoid

• Using a home router for the whole office. It struggles once twenty devices connect.
• Unlabelled cables. Every fault then starts with an hour of tracing wires.

What to include in your enquiry

• Office size, number of cabins and floors
• Number of users and devices, and number of wired points needed
• Current internet provider and whether you want a backup line
• Whether CCTV or other systems will share the network
• Whether you need cabling, installation and annual maintenance
• Preferred completion date
