If you've ever wanted to throw your router out the window because your video call froze again, you're not alone. I'm Karl from Why Oh WiFi, and I've been diagnosing WiFi problems across Geelong for years. Here's what I've learned about why WiFi drops out – and more importantly, what actually fixes it.
The 5 Most Common Causes I See
1. Interference From Other Networks
In built-up areas like Newtown, Highton, or Ocean Grove, you might have 20+ WiFi networks competing for the same channels. Your router is constantly fighting for airtime.
Using a WiFi analyser (not the free phone apps – they can't see the full picture), you can find the least congested channel. Sometimes just switching from the 2.4GHz band to 5GHz makes a huge difference.
2. Too Far From the Router
WiFi signals don’t travel through walls and floors as well as you’d think. That room at the back of the house? It might only be getting 10% of the signal strength.
Before buying a mesh system or repeater, get a proper heat map done. I've seen people spend $500 on mesh gear when moving the router 2 metres would have solved it.
3. Your Router is Overheating
Routers tucked into entertainment units or sitting in direct sunlight run hot. When they overheat, they throttle performance or drop connections entirely.
Move it somewhere with airflow. Seriously – this is often the easiest fix.
4. Too Many Devices
The average Australian home now has 15+ connected devices. Older routers weren’t designed for this. Every smart TV, phone, tablet, and smart plug shares the same connection.
If your router is more than 5 years old and you have lots of devices, an upgrade might actually be worth it. But get advice first – you might not need the most expensive option.
5. ISP Issues
Sometimes it really is your internet provider. NBN congestion during peak hours, faulty connections, or configuration issues at the exchange.
Before calling your ISP (and spending an hour on hold), do some basic tests. If your WiFi signal is strong but the internet is slow, the problem is probably upstream.
What Won’t Fix It
- Rebooting your router every day – If you have to do this, something is wrong
- Tin foil behind your router – Please don't
- Random $50 "WiFi boosters" from online marketplaces – Usually make things worse
When to Get Professional Help
If you’ve tried the obvious stuff and you’re still having problems, a proper WiFi assessment can save you a lot of money and frustration.
I use the same diagnostic tools that enterprise consultants use – not phone apps, but professional spectrum analysers that show exactly what’s happening in your environment.
Key Takeaway
- The assessment costs $99, takes about an hour
- You'll leave knowing exactly what's wrong
- You get prioritised recommendations - from free fixes to full solutions
- No guesswork, no upselling – just honest answers
