Zigbee or Mi-Wi Signal Interference: Possible Causes and Solutions

RF or Wi-Fi interference can cause slowdowns and disconnections. They often come from devices like microwaves, mobile phones, or high-voltage lines, and from building materials such as concrete or metal. To reduce these interferences, move the sources away, optimize the router’s location, and add compatible Sinopé devices that improve stability through mesh technology.

If you experience connection difficulties, slowdowns, or intermittent disconnections of your connected devices, it is possible that interference is affecting RF (radio frequency) or Wi-Fi signals.


Here are the most common causes and possible solutions:


1. Devices That Can Cause Interference

Certain objects located near your smart devices, gateway, or router can disrupt wireless signals.


Interference can:

  • Reduce communication range
  • Temporarily block the signal
  • Cause intermittent disconnections

Devices that can create interference:

  • Microwave oven
  • Direct satellite service
  • High voltage lines or electrical box
  • Mobile phones
  • Speakers and wireless devices
  • Certain external monitors and LCD screens

If possible, move these devices away from your router, gateway, or smart devices.

2. Building Materials That Can Affect the Signal

The materials used in your home can also reduce the range of RF and Wi-Fi signals.

Materials Interference Potential
Wood, synthetic materials, glass Low
Water, brick, marble Medium
Plaster, concrete, bulletproof glass High
Metal Very high

Concrete walls, metal structures, or certain types of insulation can significantly weaken the signal.

3. How to Reduce Interference

If you suspect the presence of interference:

✔ Move possible sources away

Temporarily stop using the device that may be causing the interference or move it away from your smart devices and router.

✔ Optimize the router’s location

  • Place it in an open space
  • Avoid metal furniture
  • Install it in the center of the area to cover, if possible

4. Using a Repeater or Adding Devices

Sinopé devices from the Mi-Wi and Zigbee ranges operate with mesh technology.


This means:

  • The signal is transmitted from one device to another.
  • Each new compatible device acts as a repeater.


If communication seems weak, adding a compatible Sinopé device can improve network stability.
