Wi-Fi Setup for Australian Small Businesses: A Practical Guide

Introduction

Reliable Wi-Fi isn’t optional for business anymore. Staff need it for their laptops and phones. Customers expect it. Your point-of-sale might depend on it. When the Wi-Fi goes down, work often stops.

This guide covers how to set up and maintain reliable wireless networking for your small business.

Assessing Your Needs

Coverage Area

Where do you need Wi-Fi?

• Main work areas
• Meeting rooms
• Reception/customer areas
• Break rooms
• Outdoor areas
• Warehouse/workshop

Map out where coverage is needed.

Number of Devices

Count devices that will connect:

• Staff computers/laptops
• Staff phones
• Tablets
• Point of sale systems
• Printers
• Smart devices
• Customer devices

Add buffer for growth and guests.

Usage Type

What will people do on Wi-Fi?

Light Usage

• Email
• Web browsing
• Basic cloud apps

Medium Usage

• Video calls
• File sharing
• Cloud applications
• Media streaming

Heavy Usage

• Large file transfers
• Multiple video conferences
• Creative work
• Multiple devices per person

This affects how much capacity you need.

Equipment Basics

Router

Your router connects to the internet and manages your network:

ISP-Provided Router

• Often basic capability
• May be adequate for very small offices
• Limited features and control

Business Router

• More features and control
• Better reliability
• Security features
• ~$200-600

For most small businesses, a decent business router makes a difference.

Access Points

If one router doesn’t cover everything:

Wireless Access Points (WAPs)

• Extend coverage
• Connect via ethernet cable
• Professional grade: $150-400 each
• Consumer grade: $50-150 each

Mesh Systems

• Simpler setup
• Wireless connection between units
• Easier management
• $300-600 for multi-pack

Network Switch

If you need more ethernet connections:

• Connects multiple wired devices
• Different port counts (8, 16, 24, 48)
• Unmanaged (simple) vs managed (configurable)
• ~$50-300 for basic business switches

Setting Up

Step 1: Internet Connection

Ensure adequate internet speed:

NBN Tiers for Business

• NBN 50: Adequate for small office, light use
• NBN 100: Better for video calls, file sharing
• NBN 250/1000: For heavier usage

Business plans typically offer:

• Better support
• Service level agreements
• Priority repair

Step 2: Router Placement

Position matters:

Do

• Central location
• Elevated position
• Away from interference sources
• Good ventilation

Don’t

• Hidden in cupboard
• On floor
• Next to microwave or other electronics
• Behind metal obstacles

Step 3: Basic Configuration

Access your router admin panel:

1. Connect computer to router
2. Open browser
3. Go to router IP (usually 192.168.1.1 or 192.168.0.1)
4. Login with default credentials
5. Change admin password immediately

Essential Settings

• Admin password (change from default)
• Wi-Fi network name (SSID)
• Wi-Fi password (strong, unique)
• Update firmware

Step 4: Wi-Fi Security

Encryption

• Use WPA3 if devices support it
• Otherwise WPA2-Personal
• Never use WEP or no security

Password

• At least 12 characters
• Mix of letters, numbers, symbols
• Not guessable
• Different from admin password

Hide Network Name (Optional)

• Slightly more secure
• Less convenient
• Matter of preference

Step 5: Guest Network

Separate network for customers/visitors:

• Different password
• Isolated from business network
• Limited bandwidth (optional)
• Terms of use (optional)

Most modern routers support this easily.

Expanding Coverage

When You Need More

Single router not enough when:

• Dead spots exist
• Connection drops at distance
• Multiple floors
• Large area
• Building materials block signal

Options

Additional Access Points

• Wired back to router (best)
• Professional solution
• Seamless roaming possible

Mesh System

• Easier setup
• Wireless connection between units
• Good for retrofit
• May have slight performance trade-off

Range Extenders

• Cheapest option
• Creates separate network
• Performance limitations
• Good for small improvements

Professional Installation

Consider professional help for:

• Large areas
• Multiple floors
• Complex buildings
• Business-critical requirements

A proper site survey ensures you get coverage where needed.

Separate Networks

Why Separate

Different networks for different purposes:

Staff Network

• Business devices
• Trusted users
• Full access

Guest Network

• Customer/visitor devices
• Internet access only
• Isolated from business systems

IoT Network (Optional)

• Smart devices
• Cameras
• Point of sale
• Separated for security

How to Set Up

Most business routers support multiple networks:

• Configure VLANs (virtual networks)
• Set up separate SSIDs
• Apply different security policies
• Limit access between networks

Technical, but important for security.

Security Best Practices

Basic Security

• Strong, unique passwords
• WPA3 or WPA2 encryption
• Updated firmware
• Changed default admin credentials

Additional Protection

• Separate guest network
• Firewall enabled
• Disable WPS
• MAC filtering (limited usefulness)

Ongoing

• Regular password changes
• Firmware updates
• Monitor connected devices
• Review access regularly

Troubleshooting Common Issues
