After You Get Your Result
📋 Real Example — Home Network Audit
A Wollert family's router audit showed three unknown devices connected to their network. One was a neighbour's phone using their default password. We changed credentials, updated firmware, and enabled MAC filtering — resolving an ongoing security exposure.
What's Actually Causing This?
Understanding the cause helps you make better decisions — and helps us fix it faster.
Router Placement
A router in a cupboard, behind a TV, or on the floor loses 30–50% of its effective range. Central, elevated placement makes a measurable difference.
Wi-Fi Channel Congestion
In dense suburbs, many routers on the same channel (usually 6 or 11) cause interference. Switching to an uncrowded channel immediately improves stability.
Firmware Currency
Router manufacturers patch security vulnerabilities and performance bugs via firmware updates. Unupdated routers are a common security and reliability risk.
Device Count vs Bandwidth
Streaming 4K on multiple devices while gaming and video calling exceeds the practical capacity of most NBN 25 or 50 plans. An upgrade may be the solution.

Key Questions
Is It Worth Fixing? Can It Get Worse? Hardware or Software?
Network vs device: If all devices have problems simultaneously — it's the network (router, NBN, ISP). If one device has problems — it's that device. This tool diagnoses the network layer. Device-specific faults need separate investigation.
What an unaudited network risks: Default router passwords are trivially guessed by automated scanners. Unknown devices on your network can access shared files and printers. Outdated router firmware has known vulnerabilities that are actively exploited.
What network remediation involves: Router password change: 5 minutes. Firmware update: 15 minutes. Channel optimisation: 10 minutes. Mesh node addition for dead zones: 1–2 hours. Most audit findings are self-service or a single professional visit.
🚨 Urgency note: Check your router for connected devices right now. Any device you don't recognise should trigger an immediate password change and security review.

Professional Help
Do You Need a Professional Repair?
✅ You can DIY if:
You can address yourself: changing the router admin password from default, updating router firmware via the manufacturer's app, repositioning the router to a central elevated location, and restarting the router monthly.
🔧 You need professional repair if:
You need professional help if: dead zones persist after repositioning; NBN speeds are consistently below 50% of your plan; unknown devices appear on your network; or your router is 5+ years old.
⚠️ What happens if you ignore this: A router running default credentials is detectable and exploitable by automated scanners within hours of internet exposure. An outdated router without firmware updates contains known vulnerabilities that are actively used to intercept traffic and redirect DNS — without any visible indication to the user.

FAQ
Questions people usually ask next
How do I know if my home WiFi is secure?
Check the router password, firmware status, encryption type, guest network setup and the list of connected devices.
Should smart devices be on the same network as my main laptop?
It is usually safer to keep smart devices and guest devices separated from the computers and phones you use for banking or work.
How often should I review router settings?
At least once a year, and again whenever you change provider, replace the router or add many new devices.
