Large houses and office buildings typically need several routers or repeaters for complete wireless coverage. A handy app makes it possible to automatically switch to the strongest WiFi connection on Android, something which the system’s default capabilities doesn’t include.
Technically, Android is able to switch between networks, but this doesn’t happen until the signal strength of the current WiFi networks goes to zero. So if you end up having a poor signal, it’s not enough for Android to make the switch to a better connection.
Luckily, an app called Wifi Switcher eliminates this problem as it can automatically switch to the strongest WiFi connection on Android. The app allows you to select your favorite WiFi connections, and also the lowest signal strength the current connection can reach before switching to a better one.
More importantly, your device needs to run Android 4.0 or a newer version and doesn’t have to be rooted. On top of that, it supports both 2.4 and 5 GhZ networks and it’s super easy to use.
How to automatically switch to the strongest WiFi connection on Android
The first thing you need to do is install Wifi Switcher by Cloudie Development from Google Play or by directly visiting the link below.

At first run, you will need to grant the app permission to access your location if your device is running Android Marshmallow or higher.
On the main screen, the app displays all nearby WiFi networks and you can pull down to refresh at any moment.
Here, you can check the boxes next to the “Preferred” options for each connection you’re using. The app will only use your “Preferred” WiFi networks when switching between connections.
The app also comes with an essential collection of Settings which you can access from the three-dot menu located in the top-right corner of the main screen. In the Settings menu you can use the slider next to the Switch Range option to define the signal strength threshold.
Android only makes the switch when the current network is at zero strength. You can set the slider to the value at which the connection becomes difficult to use, in order to switch to a better network sooner.
The app can also be set to “Ask Before Switching” so you can be notified when your phone finds another network and of course, this means automatic switching will be disabled.
Lastly, there’s the “Show Full SSID” option that can be useful for routers with very long names that are only partially shown in the list of connections.
