Understanding Android Wi-Fi Settings And Connections

Android tablets and most android mobile phones have the ability to connect to Wi-Fi wireless networks.

Wi-Fi is common wireless technology for connecting devices together on small business/home networks.

The same technology is used in public Wireless connection points, like coffee shops and hotels, for connecting to the Internet.

Before we look at how you setup and configure Wi-Fi on Android it is useful to have a basic understanding of how Wi-Fi networks work.

Wi-Fi Overview

Wi-Fi supports three connection modes:

Infrastructure mode is the most common and it is the mode used in home/business and public Wi-Fi networks.

Infrastructure mode requires a Wireless Access point which is usually provided by your home Wireless router.

The Access point forms the Wireless network, and all nodes or clients connect to the access point. See Setting up a home network.

The access point, and network is identified by a SSID or security identifier.

A Wi-Fi access point is also configured to use a preset Wireless channel. Commonly used channels are 1,6,11. See Wiki

If you are responsible for setting up your home Wi-Fi access point /router then you would the access point up to use a channel that isn’t being used by another access point in your location.

You can use wi-Fi test Apps on your device to see what channels are being used in your location.

Wi-Fi Connection Manager

Android phones and tablets come with a Wi-Fi Connection Manager, which lets you manage your Wi-Fi connections.

There are also many more sophisticated connection manager Apps available to download from the Google Play store.

The connection manager will automatically scan for Wi-Fi networks and lets you add and remove wireless connections.

To Open the connection manager go to Settings>Wireless and Network and press on the Wi-Fi Link.

The connection manager will open and display a list of Wi-fi networks that are currently in range and their status, as well as Wi-Fi connections that have been saved.

• Connected – you are currently connected to this network
• Saved– this network is already setup and you can connect to it
• None– This network connection hasn’t been setup yet.
• Out of range – Saved connection not in range.

To connect to a new network press the network name and enter the network password or passphrase if the network is secured.

Once you have connected the connection settings are saved so that you don’t need to re-enter the password each time you connect.

If you don’t know the password then you might be able to use the WPS option if it is available on the Wireless Access Point (see later)

Older versions of the Android the connection manager show how the connection is secured, and if it supports WPS

Secured and Unsecured Networks

Most networks are secured which means that you will need to enter a password or passphrase to connect to them.

On a secured network the network traffic is encrypted and not vulnerable to eavesdropping.

Most public networks use unsecured networks and don’t require a password to connect to them.

However some have a secondary login web page that you need to login to in orderto connect.

You should be careful when using any public networks even secured ones. See Connecting Your Android Tablet to Public Wi-Fi Hotspots

WPS Setup (Wi-FI Protected Setup)

Android supports WPS which lets you connect to a new network without having the manually enter a password.

However to use it your Wi-Fi router/access point must support it, and have it enabled.

The old connection manage shows the WPS link above the network list.

On Android 5 and above you need to press the more link and select advanced.

There are two option available the easiest and quickest is the push button option.

This again requires support at the Access point and you must have physical access to the access point to press it.

This article explains the procedure in more detail.

Public Network Notifications

By default this option is enabled, and so when android detects a new unsecured network it will notify you. (screen shot above)

However it will not automatically connect to the network.

Moving With Android

As you move around with your tablet/phone you will come into range of other networks, some maybe new, others will already be saved. You will also fall out of range of the network you are currently connected to.

As you move and lose an existing connection Android will automatically connect to another saved network that is in range.

If it comes across a public network you will receive a notification and a prompt to allow you to connect.

There is a new feature available in Android 5.1 and above on Google nexus phones and tablets called Wi-Fi assist which will automatically connect you to trusted public networks that are available.

You can also get Apps from the app store that do the same thing.

Quickly Enable and Disable Wi-fi

You can tell whether or not Wi-Fi is enabled or disabled by looking in the system status area on the top right of the screen.

To enable or disable Wi-fi go to Settings>Wi-Fi>Wireless & Networks and toggle it on or off.

Viewing Your Saved Networks

You can see a list of all of your saved networks by going to Settings>wi-fi>Wireless & Networks. Press the more link (three vertical dots top right) and press saved networks.(Android 5 and above)

Removing a Saved Network

To Remove a network from the saved list click it and then click forget

The next time you try to connect to that network you will need to enter the password.

Airplane Mode and Wi-Fi

If you turn on Airplane mode which is a requirement when flying the Wi-fi and Bluetooth networks are disabled by default.

However you can enable them once you are in Airplane mode providing the operator allows this.

Here is a video which take your through the process:

Wi-Fi Direct

Wi-Fi direct allows you to connect two Wi_Fi equipped devices together without requiring an access point.

Essentially it works the same ways as Bluetooth but is much faster and is designed to be used for the same type of applications.

Here is a video from the Wi-Fi Alliance that explains how it works.

Here is video that shows you how to transfer files between phones using Wi-Fi direct and EFS file explorer.(skip to about 3:45.

Common Questions and Answers

Q- Will turning Off Wi-Fi save battery life?

A- Yes Next to the screen Wi-Fi is probably the next biggest drain on you battery and if you are reading Kindle Books on your Tablet you don’t really need to be connected to the Internet.

Q- I’m having trouble connecting in certain parts of my house?

A- Wi-fi signals don’t travel too well through walls and if you live in a large house then you may need install a second Wi-Fi access point to get a better coverage. See extending a home network on my other site.

If you have several access points in your house and find that you still have problems make sure you are connected to the access point that has the better signal.

Q- Will Pressing the WPS button on my Home router change my current Wi-Fi password?

A- No it just allows another device to connect without having to enter the password.

In This Article

This article explains how to connect your Android device to a Wi-Fi network. Instructions apply to devices from any manufacturer with Android 10, 9.0 Pie, or 8.0 Oreo, but the process for other Android versions is similar.

Turn On Wi-Fi On Android 9.0 and Up

Here’s how to make sure that Wi-Fi is turned on:

Turn on the Wi-Fi toggle switch.

Alternatively, swipe down from the top of the screen and tap the Wi-Fi icon if it’s greyed out. To open the Wi-Fi settings, tap and hold the Wi-Fi icon.

Turn on Wi-Fi on Android 8.0

The process for enabling Wi-Fi and adjusting settings is different for Android 8.0. Here’s how to open the Wi-Fi settings on these devices:

Connect to a Wi-Fi Network

Once Wi-Fi is enabled, go to Settings > Connections > Wi-Fi to see a list of nearby networks to which you can connect.

What to Consider Before Connecting

A network with a lock icon is secured and requires a password; it’s preferable to an unsecured one because it’s less vulnerable to intruders. If you must connect to an unsecured Wi-Fi network, use a firewall or antivirus app. Consider using a VPN, as well.

Don’t use an unsecured network for private browsing activities, such as accessing a bank account and logging in to your online user accounts.

Choose the strongest network available. The estimated signal strength displays next to each Wi-Fi network. The darker the icon or the more bars that display, the stronger the network signal is.

View Details About the Wi-Fi Connection

After your Android is connected to Wi-Fi, you can view details about the connection by tapping the network name and then tapping Advanced.

This interface varies slightly with Android version.

Get Notified About Open Wi-Fi Networks

You can set up your Android to automatically tell you when a network is available, as long as Wi-Fi is turned on (even if not connected). Here’s how:

Turn on the Open network notification or Wi-Fi notifications toggle switch.

Choosing the Right Network

If you’re connecting to your home Wi-Fi network, you can find the default SSID and password on the bottom of your router or in the documents your ISP provided at signup. To connect to a network that isn’t yours, ask the owner for the name and Wi-Fi password.

To find the Wi-Fi password on an Android, open the Google Play Store app and search for and install Solid Explorer File Manager. From the home screen, tap Menu (three lines), go to Storages, and tap Root. In the root filesystem, tap data > Grant > misc > wifi > wpa_supplicant.conf. Choose a text editor; under the network block, find the entry for psk to view the password.

To share a Wi-Fi password from iPhone to Android, find and install a QR code generator app on the iPhone, such as Visual Codes. Launch the app and tap Add Codes > Connect to Wi-Fi. Enter the network’s SSID, Wi-Fi password, and security type (likely WPA). Enter a name in the Label field and tap Create Code. Scan the code with your Android to connect to the network.

To turn on Wi-Fi calling on Android, enable Wi-Fi on the device and connect to a network. Go to Settings > Wireless and Networks > More and tap Wi-Fi Calling to enable the feature. When Wi-Fi calling is enabled, you’ll see a Wi-Fi phone icon in the status bar.
