Obstacles that Interfere with Your Wi-Fi Signal

Sep 30, 2020Blog

There are certain obstacles in your home that ​reduce the range of your wireless network and cause Wi-Fi interference. This makes an Internet connection, video streaming, online gaming, and more frustrating and difficult to do. The first step is to understand and identify what these obstacles are in your home before you can fix the issue.

Wi-Fi Interferences in Your Home

There are many things that interfere with your Wi-Fi signal:

Wi-Fi Channel: ​The channel frequency used by your Wi-Fi router, determines how well your Wi-Fi signal can travel through your home. Your wireless router (802.11n or newer), offers WiFi on two separate bands (dual bands): 2.4GHz and 5GHz.  The 2.4GHz band is more prone to interference because of the number of devices that use this frequency.  The 5GHz will be a better option to help fix inferences slowing down your WiFi connection as long as the device is in close proximity to the router/access point. 

Walls, ceiling, and doors:​ Solid structures within your home, like walls, ceilings, and doors can block Wi-Fi signals. These obstacles can create ​dead spots​ and make Wi-Fi signals weaker or non-existent in certain areas.

Other devices: ​Other devices in your home, like the microwave, home phones, or wireless intercoms can interfere with your Wi-Fi network. This Wi-FI interference reduces home network performance and wireless signal range.

Traffic congestion:​ Too much traffic cause congestion and can hinder your router. A congested router struggles to deliver a strong Wi-Fi signal for a strong connection.

These common obstacles negatively impact your home network’s performance, but fortunately, you can fix the problems. Here’s how:


How to Fix Wi-Fi Interferences

Check your router’s frequency: ​If you are not satisfied with your network performance and your router​ ​uses both the 2.4 GHz and the 5 GHz, switch your devices to the 5 GHz network for better coverage.

Re-locate your router: ​If your router is tucked in a corner, in a distant room, or in the basement, re-locate it. Place it in a central location up off of the floor. This reduces interferences, bringing it closer to the devices trying to connect.

Change the channel on your router: ​It’s possible that too many devices are competing to connect to the same Wi-Fi channel. So, change the channel for important devices. You can use a network analyzer or ​network management tool​ to find a less congested channel. Or, you can ​set up a guest network​ for more critical devices so that the traffic is divided.

Upgrade your router: ​An outdated router struggles to perform. If you have an older router, consider upgrading it for better network performance.

Use MoCA network adapters and Wi-Fi extenders: ​Turn to a wired solution so that wireless interferences aren’t a thing. This doesn’t have to require a home network overhaul or expensive and messy installation. You can use devices called ​MoCA network adapters​ to create reliable connections every time. Plus, using ​Wi-Fi extenders extends wireless coverage to every corner of your home. The two devices in combination give you the best of convenient wireless and reliable wired setups.

Don’t let Wi-Fi signal interferences get you down, especially when there are easy ways to fix the issues. Like investing in wired solutions like MoCA Network Adapters and Extenders to deliver solid, fast speeds to every corner of your home, eliminating Wi-Fi interferences.
