Wi-Fi interference: What items can slow down the Internet speed in an apartment?

September 18, 2023  20:24

Sometimes problems with your Internet connection on your home network can be caused by more than just the specifications of the router, your ISP, or the device itself: some items in your house can also impact the speed and stability of your Wi-Fi.

So what items can slow down the Internet speed in an apartment?

  1. Microwave: The microwave oven emits electromagnetic radiation at a frequency close to that of the router (approximately 2.4 GHz). If used simultaneously, interference and interruptions in the Wi-Fi signal may occur.
  2. Walls: Walls, especially those made of brick, marble and concrete, can slow down or weaken the router's signal, making it difficult for it to propagate indoors.
  3. Cordless Landlines: If you have an old cordless landline in your apartment, it may also be interfering with the Wi-Fi signal.
  4. Bluetooth devices: Wireless mice, keyboards, or even an electric kettle that are too close to the router can interfere with the Wi-Fi signal.
  5. Aquariums: Large aquariums with water and glass can also interfere with the Wi-Fi signal if the router is nearby.
  6. Large furniture and decor: Large furniture and decorative items in the apartment, such as antique cabinets or decorative items, can slow down the Wi-Fi signal.
  7. Mirrors: Mirrors in the apartment can reflect the router's radio waves, which can also reduce the signal quality.
  8. Radio-controlled toys: Signals from radio-controlled toys can interfere with the Wi-Fi signal and weaken it.

It's important to remember that while these items can interfere with Wi-Fi, modern routers usually have technologies and features to minimize the impact of such interference. However, if you encounter problems with Wi-Fi, it is worth considering the environment and the location of the router indoors.
