How to improve and enhance the WiFi signal on Android

Cómo mejorar y potenciar la señal WiFi en Android - El Androide Feliz


What good is a mobile phone that cannot access the Internet? The truth is that we are a little lame. If we have run out of data, we will most likely try to hook up to a wireless network, using applications such as WiFi Master Key and the like to discover free access points around us.

Wi-Fi is also the most practical solution, especially if we are at home, but what happens if the signal that reaches our Android is very weak? In this case, it is best to sit down and spend 5 minutes improving the quality of the wireless network . We will surely appreciate it in the long run!

How to improve Wi-Fi quality on Android devices

When it comes to attacking a weak or too weak Wi-Fi signal problem, we must do it through 2 well-differentiated fronts. On the one hand, there are the actions that we can carry out on our phone or tablet, and on the other, the configuration settings that we can apply directly to the router. Let’s see what they consist of.

From the phone

Before starting to get your hands on the router, it is advisable to perform certain “maintenance” tasks on the phone.

Forget WiFi network and reconnect

When we have a Wi-Fi connection problem, the first thing we should do is delete the network configuration data and reconnect. This usually works especially well when it comes to specific failures.

We just have to go to “ Settings -> Networks and internet ”, click on the active Wi-Fi connection and in the network details, select “ Forget ”. In this way, our Android will erase all the connection settings, as well as the access password. If we had any low range issues, it will most likely be fixed “automatically” when we re-establish the connection.

Search the less traveled frequencies and channels

If after forgetting and reconfiguring the connection it still doesn’t go as fast as we would like, we must take a little more drastic measures: it’s time to roll up our sleeves and put our hands in the mud a little.

To do this, we will install the WiFi Analyzer app (or other alternatives like ESTA) to check the channels and frequencies of the networks that we have around us. This is data that will help us to know which broadcast channels are the least used . In this way, we can go to the configuration settings of our router and adjust it so that our neighbors’ Wi-Fi does not create interference and we have a much better quality connection.

Note: For WiFi Analyzer to work properly, it is necessary to give location permissions to the application (from the “Settings -> Applications” menu of the system).

Currently, WiFi signals are broadcast over 2 frequencies: 2.4GHz and 5GHz. In turn, each of these frequencies has different emission bands, also called “channels”. Thus, the 2.4GHz frequency has approximately 11 channels, with the 5GHz frequency being the widest, with 45 channels.

That said, we will open the WiFi Analyzer app and once the scan is done, we will see on which channel both our Wi-Fi and that of our closest networks emit. This will also allow us to see which channels are free .

Check the case of your mobile

Do you use a case to protect your smartphone? If so, it is advisable to remove the case and see if the Wi-Fi reception improves. Some protective cases can significantly impair the sending and receiving of wireless signals, especially if the case has metal components .

To find out if we have a “wifi blocker” case, the best we can do is perform a speed test , first with the case on and then with the case removed. If we notice a big difference, it is time to replace the case with a new one.

Is your mobile compatible with Wi-Fi 6?

Many modern smartphones already support the new wireless standard called Wi-Fi 6 (802.11ax) . Wi-Fi 6 connections allow an improvement in performance up to 4 times higher, which can undoubtedly make a difference when there is a long distance between the mobile and the router.

If your router offers connections with Wi-Fi 6 and your mobile is compatible, you will see that the symbol that appears in the notification bar when you connect to Wi-Fi has the number 6 right next to it.

This is an automatic configuration, so we do not need to do anything on the Android device.

Now that we know this, the next step is more than obvious: enter the router configuration menu and change the channel of our WiFi network.

from router

To be able to enter the router we will need 2 data:

  • The IP address or gateway of the router.
  • The user/password for access (not to be confused with the user/password to connect to the WiFi network).

If you have problems accessing, take a look at the post “How to access a router”.

The configuration panel of each router is different, although in most cases they have quite similar interfaces. For example, in the settings of the TP-Link router in the image below, we can modify the channel from the menu “ Wireless network -> Wireless network settings ”.

Once we have found the section that refers to the channel, we only have to change it to one that is free (according to the data collected with the Wifi Analyzer app).

Remember that the 5GHz frequency is usually less used, so if you have a compatible router, you will probably find more free channels on this frequency. Of course, although the transmission speed is much more powerful in 5GHz wireless networks, the range is also much more limited.

Install a Wi-Fi repeater in the areas furthest from the router

If after changing the channel we still receive a very weak signal in some rooms, it is advisable to install a Wi-Fi repeater . They are not very expensive – they are usually around 20 or 30 euros – and they will help us to amplify the signal throughout the house. I currently use the TP-Link N300 TL-WA850RE, and for a medium-sized apartment the truth is that it works very well.

How to improve the wifi signal when we are on the street

All this is fine if we are at home, but when we are in public places connected to other networks, we obviously cannot touch the router. Although in these situations the options are much more limited, we can always keep this couple of tips in mind:

  • Do not move a lot : If we are connected to the Wi-Fi of a library or a shopping center and we do not stop moving, we will jump from one access point to another. This causes the signal to weaken.
  • Avoid Obstacles : WiFi often has trouble getting through walls. Other objects such as doors and other obstacles can also weaken the wireless signal. Try to stay in the largest rooms (or as close as possible to the router or a repeater).
  • Do not install Wi-Fi boosters or apps to boost Wi-Fi : Most of these apps have no real effect on our device, and do not provide anything beyond the actions and advice that we have discussed throughout this post.
