Is Interference Slowing Down your WiFi Connection?

Is your WiFi slower than it should be? The reason may be interference. It’s a silent affliction that could be robbing you of the speed that you pay for; so evenif your 802.11ac router supports gigabit speeds, for example, you may see far less.

We’ve compiled the top 5 sources of WiFi interference and have some quick fixes that you can employ to reduce its effect on your connection.


Top 5 Sources of WiFi Interference


  1. Everyday Appliances like microwaves and florescent lights, power cables & adapters etc. They emit signals that can interfere with your WiFi.
  1. Wireless Devices including wireless headsets, keyboards, mice, activity trackers, cordless phones, baby monitors etc. Just like the appliances above, the wireless signals they use to communicate with other devices can slow things down… a lot.
  1. Household Gadgets commonly used, such as video game controllers, wireless security cameras, radar motion detectors, analog audio systems can be a major cause of interference.
  1. Building Materials: In general, dense materials such as concrete, metal and stone are not good for wireless signals. Reflective surfaces such as mirrors and foil found in modern housing insulation can cause erratic WiFi signals.
  1. Neighboring WiFi Networks: The growth in WiFi network density, especially in populated areas has increased interference among wireless networks. Strong WiFi signals in close proximity to each other can reduce the performance of both networks. New Public WiFi networks are adding to this form of interference.


Tips to Fix WiFi Interference

Now that you know what kinds of things cause WiFi interference, here’s what you can do about it:

  1. Relocate your wireless router away from nearby routers, appliances and dense building materials.

  3. Unplug the appliances and devices when not in use.

  5. Avoid using too many wireless gadgets at the same time within close proximity of each other.

  7. Try using different wireless frequency (5GHz vs. 2.4GHz) and/or a different wireless band.

  9. Consider upgrading your wireless router or at the very least upgrading the firmware (newer technologies and configurations can avoid the susceptibility of earlier solutions).
