f you have had your WiFi password set for a long time, you may not remember it. This can be a problem, especially when you try to connect a device to the network. The following tutorial will show you how to retrieve the password using an Android phone that has previously been connected to the network.

Before retrieving the WiFi password, make sure that your phone is rooted. Because each phone has different a rooting method, a Google search may help you.
1. Open the Play Store. Then search for and install the Root Browser Lite (free) app if you do not have it on your phone yet.

2. Once you have installed the app, return to the app drawer, and launch the app from there.

3. When the app is loaded, navigate to the Data/misc/wifi folder. Find thewpa_supplicant.conf file and tap on it.

4. Use the RB Text Editor to open the conf file. It should be fine if you use other text editor apps to open the file, but the default one works just as well.

5. When the content of the conf file shows up, find the network from which you want to retrieve the password. The SSID row is the name of the WiFi network, and the PSK row will show you the password of that WiFi connection.

6. Try connecting a different device to the WiFi network using the retrieved password to provide you have the correct password.

Usually, when a user wants to copy music files, videos, or images to an Android phone, he has to connect it to a computer using a cable. Repeating this task over time can be a bother.

One of the first questions my Android-using friends want to know is how to move files between their devices and their computers.
To make this task possible your computer and your Android phone must be on the same wifi network.
1. Open the Play Store from the app drawer. Search for and install the AirDroid(free) app to your phone.

2. Once you have installed the app, launch it. You should see a passcode, which has six characters, at the bottom of the page. Please take note of this code as we need it later to access the phone from the computer browser.

3. Launch your favorite browser, and open this address: web.airdroid.com. Then enter the passcode from the previous step to continue.

4. If successful, you will see the interface below. The right side of the page shows your phone model and a brief summary of the phone memory status. You can use this interface to do numerous tasks such as managing and sending messages or viewing the call logs, contacts book, pictures, videos, etc. To send a file from the computer to the phone, click the Files icon.

5. Click the Upload button at the top right of the new window to process.

6. Choose Select Folder or Files, and then select the folder/files that you want in the Explorer window.

7. Check the Progress status page to see whether or not the files were sent to the phone. When complete, the Progress column should read Success.

8. Close the browser’s window when you are done.
