September 25, 2023

In today’s digital age, a strong and reliable WiFi connection is essential for everything from streaming your favorite shows to working from home. But what do you do when your WiFi signal starts acting up? Often, the culprit is interference, and it can come from unexpected sources right in your own home. In this post, we’ll explore 7 common causes of WiFi interference and provide simple solutions to help you get the most out of your wireless network.

LED Lights

Cause: LED lights, especially dimmable ones, emit radio frequencies that can interfere with WiFi signals.

Solution: Opt for LED bulbs that are labeled as “WiFi-friendly” or consider switching to incandescent bulbs in critical areas.

Water Pipes

Cause: Water pipes can absorb and reflect WiFi signals, causing disruptions.

Solution: Relocate your router or use a WiFi range extender to bypass the interference from pipes.


Cause: Mirrors with metal backing can bounce WiFi signals, creating dead spots.

Solution: Reposition your router to minimize reflections or place a reflective shield behind it.

Smooth Tabletops

Cause: Reflective surfaces like glass tabletops can scatter WiFi signals.

Solution: Add a tablecloth or choose tables with textured surfaces to absorb reflections.


Cause: Large furniture, especially with metal or water-containing materials, can obstruct signal paths.

Solution: Relocate your router or strategically rearrange your furniture to create a more open WiFi-friendly space.

Microwave Ovens

Cause: Microwave ovens emit strong electromagnetic waves that interfere with WiFi signals.

Solution: Position your router away from the microwave or schedule internet-intensive tasks when you’re not using the microwave.

Motion Sensors

Cause: Motion-activated devices can occasionally disrupt WiFi signals when they activate.

Solution: Adjust the sensitivity or location of your motion sensors, so they don’t trigger your WiFi disruption.

A smooth and uninterrupted WiFi experience is crucial in today’s connected world. By understanding the common sources of interference in your home and implementing these simple fixes, you can ensure a stronger, more reliable WiFi signal for all your online activities. So, say goodbye to buffering and dead zones, and enjoy a seamless browsing and streaming experience!
