How to change your WiFi channel for power and placement

WiFi is not a complete network, it has failures, falls, slow … Sometimes, that may be because the router is in bad shape or doesn't have much power, because your mobile antenna is not working well or to be disturbed. In fact, it is very possible that this is the cause and the root of the problem is at the stations.

We'll review which channels, how to know which one uses our router, which are the easiest to use, how to change everything directly from our Android device.

WiFi channels and interruptions

Let's start with the basics. Most of the WiFi routers are broadcast in the 2.4 GHz range, which is high quality and on all phones compatible. This ranges from 2,412 MHz to 2,472 MHz and is divided into 13 channels. These 13 stations broadcast a total of 100 MHz, but each has 20 MHz, so when we create accounts … they don't go out. Unless the channels overlap, of course.

That is exactly what is happening. The channels overlap, for each channel to take part in low visibility. In the picture above you can see it in a more graphic way and a clear example is channel 1, whose band reaches channel 3. That means that the router broadcasting on channel 1 will cause interference on the router broadcast on station 2 and on the other broadcast on station 3, so everyone and everyone.

The only solution available move to 5 GHz band, not too old as it has 25 stations with no overhead speed and high speed capacity (albeit a small distance), but not all passengers can broadcast on that band, over all the older ones. Also not all phones have a 5 GHz band compatible antenna, so it's not a solution, say, overall. What have we left? Change channel

Before changing the channel you must know which one we use

And which channel should you switch to? To a lesser extent, of course. Knowing what it is you can use a free and fully featured Google Play app called WiFi Analyzer. This will show you all WiFi routers are streaming near you, its power and the channel they use in the graph.

As you can see above, we have endless streaming routers on the same channel or full on us, which can cause interruptions, drops, slow speeds, etc. With this information we have enough to change the channel, but we can move on.

If you swipe three times you will reach a position. Click on "Select your AP" and select your WiFi network. It will show you which channel you're currently using again Which, according to those closest to you, is that you have to change to have high communication. The 14 will always go out with all the stars, but they can't be used. For us, we use 4 and we'll be interested in getting you to 14 (which we can), to 13 or 12.

And now we're changing it fast

We know exactly the right route, now it's time to change it to our router. To do this, open any web browser, either on your mobile phone or computer, too write address 192.168.1.1. It will ask you for confirmations that, if you have not changed it, you are probably an administrator / administrator, of 1234/1234 or a combination of both.

Now it will depend on the router that you have access to one place or another, but basically you should look for the option to change the broadcast channel. On our router, which is the ZTE F680, the option is on "Network"> "WLAN Radio 2.4G". By default it is often used by default, a recommended option since, in theory, choose the one that best fits our space, but if you still want to change it, select the corresponding section and change it.

Keep the conversion and voila, channel changed. In theory you should be aware of the smaller cuts and the better the connection. It may be temporary, because if your neighbors routers are set to automatic and you find that the channel you are using is best, they will be changed and you will have to repeat the process. At least you already know how to do it.
