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.
WiFi-dropping calls we get in Geelong come down to one of five fixable causes — none of which require a new internet plan.
The hardest part of fixing WiFi drop-outs isn’t the fix itself — it’s working out which one of five usual suspects is actually responsible at your place.
The 5 most common causes I see
The five suspects, ranked by how often I see them
Other networks fighting for the same channel — common in built-up suburbs.
Distance from the router — back rooms get a fraction of the signal.
Router overheating in a cabinet or sun.
Too many connected devices for an older router to handle.
An actual ISP-side problem — the line, not your gear.
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 proper 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. There’s a deeper walkthrough in my 2.4GHz vs 5GHz guide.
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 extender, 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. If you genuinely do need mesh, my mesh WiFi guide walks through the decision.
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. Off the floor, out of the cupboard, away from the TV. 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. My diagnose-your-internet guide walks you through it step-by-step.
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 enterprise consultants use — not phone apps, but professional spectrum analysers that show exactly what’s happening in your environment.
If the problem is patchy coverage rather than dropouts, my dead spots in Geelong page covers the most common patterns I see across local suburbs.
Key takeaway
- The assessment costs $149 flat, 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
Common questions
How often should a WiFi router actually need a reboot?+
A healthy router shouldn't need scheduled reboots at all. If you're rebooting weekly to keep things working, something else is wrong — usually overheating, an old/dying router, or a firmware bug. A nightly auto-reboot timer is a band-aid, not a fix.
My WiFi drops out every evening between 7-10pm. Is that the router or the NBN?+
Evening-only drop-outs are usually one of two things: neighbour WiFi congestion (everyone's home and on their devices) or congestion further upstream at the local Point of Interconnect (POI — the spot where your ISP plugs into the NBN backbone). A 30-second test: plug a laptop into the router with an ethernet cable. If the drop-outs still happen wired, it's upstream. If wired is rock-solid, it's a WiFi problem.
Will a WiFi extender fix my drop-outs?+
Usually no. Cheap extenders halve the speed of whatever they rebroadcast and add a second network you have to manually switch between. They patch coverage in one corner but rarely fix actual drop-outs. Mesh — done properly, ideally with the units wired to each other — is the real answer for whole-home coverage.
How do I know if it's my WiFi or my internet plan?+
Plug a laptop directly into your router with an ethernet cable and run a speed test. If the wired result is what you're paying for and feels stable, your internet plan is fine — it's the WiFi side that needs work. If the wired result is also slow or jittery, it's your ISP or NBN connection.
Why does my WiFi drop only on one specific device?+
If only one phone, laptop or smart TV keeps dropping, the device's WiFi adapter is more likely the culprit than the router. Try forgetting the network and reconnecting, update the device, and check whether other devices in the same spot stay connected.
Is it worth replacing a 5-year-old router?+
If you have 15+ devices, work from home, or notice slowdowns when several people are streaming at once, yes — modern routers handle the load far better. If you live alone with a handful of devices and it's working fine, there's no urgency.
