In today’s digital age, WiFi has become an essential part of our daily lives. We rely on it to stay connected, work, and entertain ourselves. However, with the increasing number of WiFi networks in our surroundings, it’s natural to wonder: can your neighbour’s WiFi interfere with yours? The answer is yes, and in this article, we’ll explore the reasons behind WiFi interference, its effects, and most importantly, ways to minimize or eliminate it.
What Causes WiFi Interference?
WiFi interference occurs when two or more devices transmit WiFi signals on the same or overlapping frequencies, causing conflicts and disrupting the performance of one or both networks. There are several reasons why your neighbour’s WiFi might be interfering with yours:
Physical Obstacles
Physical obstructions such as walls, floors, and ceilings can weaken WiFi signals, making them more susceptible to interference. Thicker walls, especially those made of concrete or brick, can significantly reduce WiFi signal strength. Additionally, physical barriers like furniture, appliances, and even people can absorb or deflect WiFi signals, causing interference.
Channel Overlap
WiFi routers operate on a specific channel or frequency band. When two or more routers are set to the same or adjacent channels, it can cause channel overlap, leading to interference. The 2.4 GHz frequency band, which is the most commonly used band, has only three non-overlapping channels (1, 6, and 11). This means that if your neighbour’s router is set to channel 6, and yours is set to channel 5, they may still interfere with each other.
Radio Frequency Interference (RFI)
Radio Frequency Interference (RFI) occurs when devices emit radio signals that clash with WiFi signals. Common sources of RFI include:
- Microwaves
- Cordless phones
- Bluetooth devices
- Baby monitors
- Neighbouring WiFi networks
Effects of WiFi Interference
WiFi interference can have a significant impact on your internet experience. Here are some common effects:
Slow Internet Speeds
Interference can cause your internet speeds to slow down, making it frustrating to stream, download, or upload files. You may experience buffering, lag, or disconnections, which can be infuriating, especially if you’re trying to work or entertain yourself online.
Dropped Connections
Interference can cause your devices to disconnect from the WiFi network, forcing you to reconnect repeatedly. This can be especially problematic if you’re in the middle of an important task or online meeting.
Poor Coverage
Interference can reduce the coverage area of your WiFi network, making it difficult to maintain a stable connection in certain areas of your home or office.
How to Minimize or Eliminate WiFi Interference?
Now that we’ve discussed the causes and effects of WiFi interference, let’s explore ways to minimize or eliminate it:
Change the WiFi Channel
One of the simplest ways to reduce interference is to change the WiFi channel on your router. You can use tools like WiFi Analyzer to scan for nearby networks and identify the least congested channel. Then, log in to your router’s settings and switch to that channel.

Can my neighbour’s WiFi really interfere with mine?
Yes, it is possible for your neighbour’s WiFi to interfere with yours. WiFi signals can travel through walls and floors, which means that if your neighbour’s WiFi router is close to your router, it can cause interference. This is especially true if you and your neighbour are using the same WiFi frequency band (2.4GHz or 5GHz) and have similar WiFi router models. Interference can cause your WiFi connection to slow down or drop out altogether, making it difficult to get online.
The good news is that there are ways to minimize the impact of your neighbour’s WiFi on yours. By changing the WiFi channel on your router, using a WiFi analyzer app, and implementing quality of service (QoS) settings, you can reduce the interference and improve your WiFi connection. Additionally, using a mesh network system or upgrading to a WiFi 6 router can also help to mitigate the effects of interference.
How do I know if my neighbour’s WiFi is interfering with mine?
If you’re experiencing slow WiFi speeds, dropped connections, or poor coverage, it’s possible that your neighbour’s WiFi is interfering with yours. Other signs of interference include frequent reboots of your router, devices constantly disconnecting, or poor video streaming quality.
