Previously, only cable connections were used, in this case users did not suffer from channel interference problems as these do not exist , something that happens today on WiFi networks and which have been offered directly by the operators for some time now.

While connections over Ethernet are used for data exchange, wireless networks are used for several connections simultaneously , so these types of networks can have up to 13 channels available, however, not all of them are suitable in all cases.

Because there are so many channels available it increases the chances of interference between the different networks . That is why one of the most common solutions in this type of case is to change the channel . So here we will teach you a little more about what WiFi channels are and how they directly influence the network .


What is a WiFi channel and what are they for in my local network?

All this is directly related to the IEEE 802.11 standard , which is in charge of regulating all WiFi networks and, in addition, it was specified the three frequency ranges available for equipment that wants to emit this type of signal such as 2.4 GHz, 3.6 GHz and 5 GHz . These are numbers that you may have seen several times already and which are used by several devices these days.

Although it is important to mention that today most devices work with the frequency of 2.4 GHz. Each of these frequency ranges has a number of channels , so is the band of 2. 4 GHz is subdivided into 14 channels , although each geographical area has its own number of channels, is like this in Europe you work with a total of 13 channels , while in North America you work with 11 channels.

Each of these channels is usually separated by 5 MHz, but the reality is that each of them should have a distance between 22 MHz channel , which creates an overlap between each of them .

As you can see in the image shown above channel 1 overlaps with channels 2,3,4 and 5 , this means that equipment that emits its signal on one of those channels can generate interference . The same applies to channels 6,7,8,9 and 10 . That’s where the method of comes in, changing channels to improve the signal .

The most logical thing to do when the wireless signal is not working properly , is to change from the current channel to another that is being used less, thus avoiding that creates some kind of interference with other networks that could congest the operation of the same.

Therefore, WiFi channels are those that will tell you which frequency range you are in and also allow you to change channels whenever you have a very slow or unstable connection . This may be because is interfering with the signal .

Why are WiFi channels important and how do they influence signal quality?

Wireless networks can be affected by different types of interference, one of which is directly related to what is channel usage . This will depend on how many electronic devices are using the same channel for network communication .

In many cases it is not necessary that all users are using the same channel for the signal quality to be affected , but it can also be due to adjacent channels that are causing a frequency overlap .

This means that it is the channel that dictates the quality of the frequency that the user will receive , the less used it is the better the performance of the signal. This means that if around your home or workplace there are many wireless connections the chances are that several channels will be overloaded and others with more space.

This means that if you manage to switch to a channel that is lonelier and less congested, your connection speed will surely improve a lot, providing you with a better Internet service . This means that the frequency channels are extremely important for what is network performance and signal quality. However, you may be wondering: c or how can you tell on what channel your router is on? you can find out by following the section below.

From the computer

Being able to know that frequency channel is using the router at home is very important. If you have a computer with Windows Vista or Windows 7 or higher you will be able to perform the steps below:

  • The first thing to do is to open the console of “Commands”, to do this you select “Start” and type “CMD” in “Command Prompt”.
  • When you get the “Command Prompt” window on your screen you have to type the following command: netsh wlan show all and press the “Enter” key.
  • In the next window you will see which channel your WiFi network is on and you can also check the signal of your network , in this case you can see that is on channel 8 and with a signal of 87%, which means that this channel has almost no interference and is working correctly .

If you are one of the users who likes to see more graphics and things in more detail, then you can make use of some of the programs that exist on the internet today and which help users to know which frequency channel they are on. One of the most popular and reliable programs nowadays is “InSsider” , here you can find a very complete analysis with graphics so you can better understand everything that is going on.

InSsider will list all wireless networks within range of your computer , where will show you the power of each and its channel, as well as which channels are creating interference . This is a free app that you can start using now.

From your mobile phone

If you want to know what WiFi channel is using your router at home from your smartphone you can do it through a mobile app, currently there are many applications available for the Android operating system that will allow you to do this type of activity.

However, in this case we would like to recommend WiFi Analyzer , an app that will give you 100% reliable results where it will show you the signal quality of your network, the channels you have available, your current channel and how used they are .

In this case you will be able to see all this information through a graphic where you will be shown which channel is using your signal and which of them are overlapping. This way you can see how good or bad your frequency is and if it’s too busy the same app will allow you to switch channels .

What should I consider when choosing the ideal channel for my router’s signal?

All routers allow the user to choose the channel on which he wants the Internet signal to be transmitted , although some of these medium and high range devices have a system that analyses the electromagnetic spectrum which allows them to automatically configure the best channel to transmit the signal .

In order to get a good signal on the router and thus have excellent coverage and network performance, it is important that the network is on a channel with little interference.

This means that the more single channel the better the speed of the network. interference or congestion of WiFi channels is a very common problem in communities where there are many wireless signals , as well as in buildings where most inhabitants have their own networks.

When there is a problem with network congestion your service is most likely to present problems of: low speed, an unstable signal, loss of signal, constant disconnections, connection problems, among others. As there are 13 channels available in the case of Europe , there will always be those that are more congested and those that are more alone.

To be able to choose the right channel for the network connection , it is important to select the one that is most alone , the more alone the channel the better the coverage. Therefore, you can start using some tools to help you change your channel and look for the one that is less congested so you can start enjoying a stable connection at maximum speed .

Steps to set up my WiFi channels to avoid cuts and interference

Bearing in mind that d depending on the WiFi channel where the network is located will be its operation, it’s important to know what the steps are to be able to configure these channels and thus ensure that you always find the network in the one that is most alone. This will allow to avoid signal cuts and interference in the operation of the network.
