When you are using the internet on your computer or mobile device, there is nothing more frustrating than encountering some sort of interference with your Wi-Fi connection. Whether you are dealing with low signal strength or a slow connection, it can be a bit overwhelming to know where to start looking for the main cause. Where are many different possible causes for wireless interference, and hopefully we can help you identify the culprit without you needing to hire a local network technical support company.

Microwave Oven: If your computer or Wi-Fi base station is located in or near your kitchen, the electromagnetic energy generated by your microwave oven may be interfering with your signal. Move your devices away from the microwave and see if that solves the issue.

Direct Satellite Service: Your satellite service – or, more specifically, the coax cable and connectors in use – could be the culprit. Radio frequency interference can be caused by damaged cabling. Be sure to examine your setup for signs of damage and try replacing the cables.

Wireless Speakers: While they are a handy way to listen to your favourite tunes, wireless speakers can interfere with your Wi-Fi network if they operate in the 2.4 GHz or 5 GHz bandwidth.

LCD Displays and External Monitors: Harmonic interference can be caused if your LCD display operates between channels 11 and 14 in the 2.4 GHz bandwidth, or if you have an external monitor hooked up to your notebook computer. To fix this issue, alter your access point to a lower 2.4 GHz channel or to 5 GHz.

External Electrical Sources: Keep your Wi-Fi device away from breaker boxes, power lines, and other sources of electricity to prevent interference.

Improperly Shielded Cables: Devices connected to your computer, such as external hard drives, could be the source of the interference if the cabling that is not adequately shielded. Try turning the device off or disconnecting it to see if your Wi-Fi signal improves; if it does, replace the offending cable.

Cordless Telephones: For those who still have a landline, you may notice that wireless interference occurs when you are using your cordless telephone. If your phone’s bandwidth is in the 2.4 GHz or 5 GHz range, it can disrupt your Wi-Fi network.

Wireless Video Transmitter: The 2.4 GHz and 5 GHz bandwidth ranges strike again. Wireless RF devices that transmit video can be the source of your Wi-Fi woes if they operate in either of those bandwidths.

Other Wireless Devices: There is a wide array of other wireless devices that function in the 2.4 GHz and 5 GHz bandwidth ranges, and any of them could be impeding your Wi-Fi connection. The list includes – but is not limited to – items such as baby monitors, wireless cameras, microwave transmitters and even your neighbour’s Wi-Fi device.

Location and Building Construction Materials: Depending on where in your home the Wi-Fi router is located, the materials that comprise the construction of your house or apartment can have a major impact on the performance of your wireless network. For example, if your computer is on a different floor than your router, the metal-reinforced concrete separating the two levels of your house could inhibit or even block the Wi-Fi signal. Metal, concrete, and plaster pose the highest risk of radio frequency interference.
