When people say “the internet keeps dropping,” nine times out of ten it isn't the internet at all - it's the WiFi between your devices and the router. Your actual connection can be perfectly healthy while the wireless link falls over. That distinction matters, because it tells you where to look. Below we walk through the usual culprits, then the fixes in the order we'd try them ourselves.
A quick test before you start: plug a laptop straight into the router with an Ethernet cable. If the wired connection is rock-solid while WiFi keeps dropping, you've confirmed it's a wireless problem - not a fault on the line - and the steps below are exactly what you need.
What actually causes WiFi dropouts
Most dropouts come down to one of these five things. Read the “you'll notice” line under each - it's usually enough to tell which one is yours.
Interference from other devices
The 2.4GHz band your WiFi shares with cordless phones, baby monitors, microwaves, Bluetooth speakers and even your neighbour's gear is crowded. When one of those fires up, your connection can stutter or drop for a few seconds - long enough to kick you out of a video call or drop a VoIP handset mid-sentence.
You'll notice: Drops happen at the same time every day, or whenever the microwave runs.
Distance and range
WiFi weakens fast the further you get from the router, and brick walls, tiled bathrooms, mirrors, foil insulation and steel-framed walls all soak up the signal. A router tucked in a cupboard at one end of the building will never reach the far corner cleanly, so devices out there drop and reconnect constantly.
You'll notice: Only certain rooms drop out; you're fine right next to the router.
An old or overheating router
Routers age. An older unit - especially a basic modem-router that shipped years ago - struggles with modern device counts, runs hot, and locks up under load. If yours is more than four or five years old, or it lives crammed behind the TV with no airflow, it may simply be dropping the connection when it's working hardest.
You'll notice: A reboot fixes it for a while, then the drops come back.
Channel congestion
WiFi runs on channels, and in a unit block, a busy street or a shared office building, everyone's routers can pile onto the same few channels. When they all talk at once they talk over each other. Your router may not automatically move to a clearer channel, so it keeps fighting for airtime and dropping packets.
You'll notice: Worse in the evening or in a densely built-up area with lots of networks nearby.
Too many devices at once
Every phone, laptop, TV, security camera, smart speaker and printer holds a slot on your WiFi. A modern home or small office can easily run 20-30 connected devices, and a cheaper router runs out of capacity - starting to drop the ones it can't keep up with, usually the device you're actively using.
You'll notice: Drops get worse when the household or office is busiest and everyone's online.
The fixes, in the order to try them
Work down this list. The first three cost nothing and solve most cases; the last two are for when the problem is genuinely the size or shape of your building.
- 1
Reposition the router
Move it out of the cupboard. Put it central, up high and out in the open - not behind the TV, not on the floor, not boxed in by a metal filing cabinet. Even shifting it to a shelf in the middle of the space can transform coverage. Keep it clear of microwaves and cordless phone bases while you're at it.
- 2
Use the 5GHz band
Most routers broadcast two bands: 2.4GHz (longer range, more crowded, slower) and 5GHz (shorter range, far less interference, much faster). For devices near the router - your work laptop, the TV, a desk phone - connect them to the 5GHz network. It sidesteps most of the interference that plagues 2.4GHz and holds a steadier connection.
- 3
Update the router firmware
Router makers push firmware updates that fix stability bugs and dropout issues. Log into the router (or its app) and check for an update - many now do it automatically if you switch the setting on. If yours is genuinely old and no longer receiving updates, that's a strong sign it's time to replace it.
- 4
Add a mesh system or extender
If distance is your problem, one router can't do it alone. A mesh system uses two or three nodes that blanket the whole property in a single seamless network, so devices hand off cleanly as you move around instead of clinging to a weak signal. It's the right fix for double-storey homes, offices with back rooms, and anywhere with thick walls.
- 5
Run a wired backhaul
The most reliable connection is still a cable. Running Ethernet to a far room - or feeding your mesh nodes with a wired backhaul instead of letting them relay over WiFi - removes the weakest link entirely. Desktops, TVs, VoIP handsets and security cameras all run rock-solid on a wired point, and it takes load off the wireless for everything else.
One honest note on speed
WiFi fixes solve dropouts and dead spots - but they can't make your plan faster than what's coming into the building. Real-world speeds always depend on the cabling to the premises, your on-site equipment and network congestion. If every device drops out at once, or the whole connection dies rather than just the wireless, that points to the line or the plan rather than your WiFi - and that's worth a proper look.
When to call us
If you've moved the router, tried 5GHz and updated the firmware and it's still dropping, it's time to stop guessing. That's usually where a mesh system, a wired point or a plan that actually fits how you work comes in - and it's exactly the kind of thing we sort on site every week across Penrith and Western Sydney. Call the shots to us:
- Dropouts that survive a router reposition, a 5GHz switch and a firmware update
- A double-storey home or an office with back rooms that never get a decent signal
- VoIP handsets or security cameras that keep dropping and need a rock-solid wired point
- The whole connection dying - not just the WiFi - which points to the line or the plan
We're a local team, not an interstate call centre - when you ring, you reach people in Penrith who can look at your actual setup. We'll diagnose the WiFi, configure the right gear on site, and if the connection itself is the problem, match you to a plan that fits.
