WiFi interference occur due to multiple signal and causes data signals to collide. When data signals collide, it cause the WiFi connection to become slow. The best way to improve the WiFi connection are to manually choose an appropriate channels for the WiFi network.
Many devices use the 2.4GHz frequency. Additionally, people often use the 2.4GHz frequency and it can be quite crowded. Each channel require 22MHz of space to function.
How to Pick the Right WiFi Channel
However, the channels are only 5MHz apart from each other. This create a problem because the signals from the WiFi router will bleed into each other. This creates noise that will impact the data signal from the router.
To avoid this, use channel 1, 6, and 11. These are the only three channels in the 2.4GHz band without overlap channels. By using these channels, the WiFi signal will be able to transmit more clear.
Many WiFi router are set to automatic for the channels. This could pick a poor channel for the devices if there are many other WiFi networks in the area. Additionally, many other device use the 2.4GHz signals.
Microwaves emit signal at 2.45GHz that can impact the signals in the middle of the 2.4GHz range. Additionally, many Bluetooth device use the 2.4GHz signal to communicate with the devices. However, the 5GHz band work differently.
The 5GHz band has more channels and more space between the channels. This allow the WiFi signal to use wider channels to increase the data speed. Using wider channels will increase the data speed but will reduce the number of available channel.
Therefore, a user must decide if they would like the increased speed or if they would like the number of available channels to be increase. One of the best option to change the WiFi channels is to use a WiFi analyzer application on your mobile device. The WiFi analyzer will scan the airwaves to find which channel other devices are using.
Then, you can choose the quietest channel. Go into your WiFi router settings and change the channel from automatic to the channel that the WiFi analyzer find as the quietest channel. For many devices such as smart bulbs and internet of things devices use 20MHz channel on the 2.4GHz channel.
This 20MHz channel provide the devices with better range. For devices such as laptops and TVs that need more data speed, use the 5GHz channel with a wider channel width. Finally, test the WiFi connection to see if the manual channel settings has improved the performance of the WiFi signal.
