How to Fix Slow WiFi at Home in Doncaster & Surrounding Areas

There's nothing more frustrating than buffering videos, slow downloads, frozen Zoom meetings, or WiFi that seems to drop out at the worst possible moment.

At The Real Geeks, helping homeowners across Doncaster, Doncaster East, Templestowe, Balwyn, Box Hill, Blackburn, Mitcham, Nunawading, Bulleen and surrounding Melbourne suburbs, slow WiFi is one of the most common issues we fix.

The good news is that poor WiFi doesn't always mean you need a faster internet plan. In many cases, a few simple changes can dramatically improve your home's wireless performance.

Let's look at the most common causes—and how to fix them.

1. Move Your WiFi Router to a Better Location

Many people place their router:

  • Inside a cupboard

  • Behind the TV

  • On the floor

  • In the garage

  • At one end of the house

Unfortunately, WiFi signals weaken as they pass through walls, furniture and other obstacles.

Better Placement Tips

  • Position your router in a central location.

  • Place it on a shelf or desk rather than the floor.

  • Keep it away from microwaves and cordless phones.

  • Avoid enclosing it inside cabinets.

  • Keep antennas upright (if your router has them).

Even moving your router a few metres can noticeably improve coverage.

2. Restart Your Router Regularly

Like any computer, routers benefit from an occasional restart.

Restarting can:

  • Clear temporary software issues

  • Improve performance

  • Refresh your internet connection

  • Resolve minor network glitches

If your router hasn't been restarted in weeks or months, try turning it off for 30 seconds before powering it back on.

3. Check How Many Devices Are Connected

Modern homes often have:

  • Smart TVs

  • Security cameras

  • Mobile phones

  • Tablets

  • Laptops

  • Gaming consoles

  • Smart speakers

  • Smart lights

  • Doorbells

All of these devices share your WiFi.

Too many active devices—especially those streaming 4K video or downloading large files—can slow the network for everyone.

4. Update Your Router

Older routers may struggle with today's internet speeds.

If your router is more than five years old, it may not support newer WiFi standards or handle multiple connected devices efficiently.

A modern WiFi 6 or WiFi 6E router can provide:

  • Better speed

  • Improved coverage

  • Lower latency

  • Better performance with many devices

Upgrading the router often makes a noticeable difference without changing your internet plan.

5. Reduce WiFi Interference

Neighbouring WiFi networks can interfere with yours—especially in apartments and townhouses.

Other sources of interference include:

  • Bluetooth devices

  • Baby monitors

  • Microwave ovens

  • Wireless security cameras

Switching to a less congested WiFi channel or using the 5 GHz or 6 GHz band (where supported) can improve reliability.

6. Check Your Internet Speed

Sometimes the issue isn't your WiFi at all.

Run a speed test from:

  • A device connected by WiFi

  • A device connected with an Ethernet cable

If both results are slow, the issue may be:

  • Your internet provider

  • Network congestion

  • An NBN fault

  • Your internet plan

Testing both wired and wireless speeds helps identify where the bottleneck is.

7. Consider a Mesh WiFi System

Large homes often have WiFi "dead zones."

Adding a WiFi extender can help, but a mesh WiFi system usually provides a much better experience.

Mesh systems:

  • Cover larger homes

  • Eliminate dead spots

  • Automatically connect devices to the strongest signal

  • Provide seamless roaming between rooms

They are an excellent option for double-storey homes and properties with thick brick walls.

8. Secure Your WiFi Network

If your WiFi password is weak—or has been shared with many people—others may be using your internet without you realising it.

Protect your network by:

  • Using a strong password

  • Enabling WPA2 or WPA3 security

  • Changing default router login details

  • Removing unknown devices

A secure network is both faster and safer.

9. Keep Your Devices Updated

Outdated laptops, phones and tablets may struggle to maintain a stable WiFi connection.

Regularly update:

  • Windows

  • macOS

  • iPhone

  • Android

  • WiFi drivers

  • Router firmware

These updates often include important performance and security improvements.

10. Get a Professional WiFi Assessment

Sometimes the problem isn't obvious.

A professional assessment can identify:

  • Weak signal areas

  • Interference

  • Incorrect router placement

  • Poor network design

  • Faulty hardware

  • Coverage issues

A few adjustments can often transform the way your home network performs.

Signs It's Time to Upgrade Your Home WiFi

You may benefit from an upgrade if you notice:

  • WiFi drops out frequently

  • Slow speeds in certain rooms

  • Buffering while streaming

  • Video calls freezing

  • Smart devices disconnecting

  • Poor gaming performance

  • Slow downloads despite paying for fast internet

These are common signs that your home network needs attention.
