You may not realise it (and there’s no reason you should) but WiFi is a simple radio signal. Just as radios fizz and crackle through signal interference, wireless signals do something similar. We experience this WiFi interference as buffering, dead zones, signal drop-outs and slow internet connections.
The end result is a frustrating experience that most of us are all too familiar with!
WiFi signal blockers more common than you might think
So what are the enemies of good WiFi?
There are many things that can cause WiFi interference. Most of these items are commonly found in homes and businesses.
Our wireless has a surprisingly tough job in the modern home or business environment. This is particularly true if you’re relying on your router for your WiFi.
WiFi interference – our top ten culprits
The following are some of the most common causes of wireless signal interference that we come across.

- Your neighbours’ WiFi
- Underfloor heating
- Building construction and materials, e.g. thick walls, reinforced concrete, metal RSJs
- Large metal objects, e.g. safe, filing cabinet, fridge, reinforced door
- Mirrors
- Electrical equipment, e.g. microwave ovens
- WiFi boosters, extenders and repeaters
- Wireless devices, e.g. baby monitors, cameras, microphones, keyboards, mice, drones, alarm systems, doorbells, and many more
- AC adaptors/power supplies
- Bluetooth devices (particularly older ones)
Is there any way to prevent WiFi interference?
In short, no. We all live and work in environments that include some, if not all, of the above.
There are some things we can do to work around the problem of wireless signal interference. For example, you can avoid clashing with your neighbours’ WiFi signal by changing the broadcast channel on your router to a different one. Or you could avoid using the microwave when you’re trying to have a Skype call!
Most of us can’t, however, change the construction of the buildings we live or work in.
Drown out the white noise with WiFi that shouts!
The only reliable solution to overcoming WiFi interference is to make sure your wireless signal is ‘loud’ enough to make it through the noise.
For most WiFi users, whether home or business, that means stop relying on your router for your WiFi signal. And if the boosters, extenders and repeaters aren’t working, stop using them too!
It’s time to invest in a robust wireless network, with dedicated WiFi access points, that’s fit for purpose.
