WiFi network setup and optimisation is essential for achieving fast, secure, and reliable internet connectivity. Whether you’re setting up a new network or improving an existing one, proper placement, heat map analysis, and security measures can make all the difference. This guide covers everything you need to know to optimise your WiFi network, improve coverage, and enhance performance.

1. Check Your Internet Connection & ISP Requirements

✅ Confirm Your Internet Plan – Ensure your broadband package provides sufficient speed for your needs (streaming, gaming, working from home).
✅ Verify Modem Compatibility – If using your own modem, check that it is compatible with your Internet Service Provider (ISP).
✅ Understand ISP Setup Requirements – Some ISPs require specific configurations such as PPPoE login details or VLAN IDs.

2. Choose the Right Router & Placement

✅ Select an Appropriate Router – Opt for a router that supports the latest WiFi standard (WiFi 6 or WiFi 6E) for better speed and efficiency.
✅ Check Coverage Requirements – If your space is large or has multiple floors, consider a mesh WiFi system or WiFi range extenders.
✅ Avoid Interference – Position the router away from walls, large metal objects, and electronic devices such as microwaves and cordless phones.
✅ Optimal Router Placement – For best performance, place the router centrally, at an elevated position, and in an open area.

3. Perform a Heat Map Analysis for WiFi Coverage

A WiFi heat map analysis helps identify weak spots in your network coverage, allowing you to optimise your setup for better performance.

Choosing the Right Heat Map Tool

There are both free and paid options available, depending on your needs:

Tool	Free/Paid	Best For	Features
NetSpot	Free & Paid	Home & Small Offices	Easy-to-use, detailed visual heat maps, works on Windows & macOS
Ekahau HeatMapper	Free (basic)	Home Users	Quick analysis, simple UI, but lacks advanced settings
Acrylic WiFi	Free & Paid	Advanced Home Users	Offers real-time analysis, network troubleshooting
WiFi Analyzer (Windows App)	Free	Basic Home Use	Shows WiFi signal strength, best suited for quick checks
Ekahau AI Pro	Paid (Pro-Level)	Large Businesses, IT Professionals	Highly detailed analysis, predictive coverage planning, enterprise-grade features
TamoGraph Site Survey	Paid	Businesses & Advanced Users	Comprehensive surveys, supports multiple WiFi standards

Which Heat Map Tool is Best for You?

• For Home Users: Try NetSpot (free version), Ekahau HeatMapper, or WiFi Analyzer if you need a simple WiFi strength check.
• For Power Users & Small Businesses: Acrylic WiFi or NetSpot Pro provide more advanced diagnostic features and troubleshooting options.
• For IT Professionals & Enterprises: Ekahau AI Pro and TamoGraph Site Survey are the best for detailed coverage analysis and large-scale network planning.

Interpreting Signal Strength

Once you run a WiFi heat map scan, check the signal strength:
✅ -30 to -50 dBm → Excellent connection
✅ -51 to -67 dBm → Good for streaming & video calls
✅ -68 to -75 dBm → Weak, may cause buffering or lag
✅ Below -75 dBm → Poor connection, needs improvement

Addressing Dead Zones

If you discover weak signal areas in your space:
✅ Reposition the Router – Move it to a central location with fewer obstructions.
✅ Adjust Antennas & Channels – Experiment with antenna direction and WiFi channel selection.
✅ Use a WiFi Extender or Mesh System – If the problem persists, consider adding range extenders or upgrading to a mesh system.

4. Configure Network Settings & Security

✅ Use a Strong SSID (WiFi Name) – Avoid using personal details in your WiFi network name.
✅ Enable WPA3 (or WPA2) Security – Use the most secure encryption to protect your network.
✅ Set a Strong WiFi Password – Use a complex password with a mix of letters, numbers, and symbols.
✅ Create a Guest Network – Isolate guest devices from your main network to enhance security.
✅ Disable WPS (WiFi Protected Setup) – This feature can be a security risk and should be turned off.

Regular Security Checks & Updates

WiFi security isn’t just about setting up strong passwords—it requires ongoing maintenance to stay ahead of cyber threats.

✅ Update Router Firmware Regularly – Router updates fix vulnerabilities that hackers may exploit.
✅ Monitor Your Network for Unauthorised Devices – Check connected devices and block unknown ones.
✅ Enable Network Logging – Keep logs to detect suspicious activity before it becomes a threat.
✅ Consider a VPN for Extra Privacy – Encrypt your internet traffic by using a VPN on your router.

---

5. Ensure Device Compatibility

✅ Check Device Support – Older devices may not be compatible with modern WiFi bands (e.g. 5 GHz or WiFi 6).
✅ Use Dual-Band or Tri-Band WiFi – 2.4 GHz provides better range, while 5 GHz and 6 GHz (WiFi 6E) deliver higher speeds.

---

6. Optimise Network Performance

✅ Set Up QoS (Quality of Service) – Prioritise important activities such as video calls and gaming.
✅ Monitor Network Traffic – Use your router’s dashboard or an app to track bandwidth usage.

---

7. Plan for Reliability & Expansion

✅ Use a Surge Protector – Prevent damage from power surges.
✅ Consider a UPS (Uninterruptible Power Supply) – Keeps your WiFi running during power cuts.
✅ Check for Mesh WiFi Compatibility – Future-proof your setup with a router that supports mesh networking.

---

8. Final Testing & Troubleshooting

✅ Check WiFi Signal Strength Again – Perform another heat map test to confirm good coverage.
✅ Test Internet Speed – Use Speedtest.net, Fast.com, or your ISP’s speed checker.
✅ Optimise Channel Selection – Choose the least crowded WiFi channel for better stability.
