You might be in a situation where the wifi speed you opted for, is greater than what you actually get. One of the main reasons for this problem could be your neighbor’s wi-fi. This problem can be fixed by using wifi analyser and by avoiding busy WLAN channels.
All the wireless devices we use are in 2.4 GHz and 5 GHz bands, which are unlicensed spectrum. And the wi-fi you and me use is in this spectrum. The main difference between 2.4 GHz and 5 GHz bands is speed, theoretically, 2.4 GHz Wi-Fi will support up to 450 Mbps or 600 Mbps and 5 GHz Wi-Fi will support up to 1300 Mbps. Also these speeds are varied with respect to the router standards you use.
What are WiFi channels? Well… In these bands there are a certain number of channels in which the wi-fi networks work. The number of channels are varied according to the users location. And each channel can contain multiple wi-fi networks. So, by identifying and avoiding the busy channel and choosing a channel with lesser number of wi-fi networks can increase the speed of the network.
To do exactly that, there are a lot of applications available on almost all operating systems. Now, I am going to share a few such applications to analyze your wi-fi and avoid busy channels.
Here are the applications for wifi analyser.
WiFi analyser for windows :
This application is available on windows 10 store, just search for it on the store or just download it using this link App link .
And once you download it and launch the application, you will get to see the active channels and the wi-fi networks connected to each of them.
Here’s the analyser graph for my network…
So, as you can see in the image above, there are 1,6 and 11 active channels. I am connected to the channel 1, and the other two channels 6 and 11 channels are weak compared to channel 1. Also the analyzer recommends channel 1. Now, as you know that your speed could be maximum in channel 1, change your channel in your wi-fi router’s wireless settings.
WiFi analyzer for Android:
For android, search for wi-fi analyzer and download the application. Here’s link for it App link.
Do the same thing here, check for the channel that is connected to less number of networks and connect to it.
And you may ask about changing the channel. Well… It’s easy, go to your router settings, select wireless settings, there you see the channels. If your router setting is set to auto select channel, turn it to manual select and choose your channel.
I hope this was helpful. Feel free to ask any questions on it!
