1. Toggle Airplane Mode On and Off
By toggling Airplane mode on and off, you will also turn the Wi-Fi connection off and on. The Airplane Mode button is placed in the notification area, which you can access by pulling down the notification bar. Your Android device will make a fresh attempt to reconnect with the network.
2. Disable Bluetooth
Bluetooth also sends out signal, which may interfere with the Wi-Fi. Some Android devices have problem connecting to a wireless network, when Bluetooth is enabled. Once Bluetooth is disabled, check whether you can establish connection with the wireless network.

- Go to Settings > Wi-Fi > Wi-Fi Network. Choose your preferred Wi-Fi connection.
- Enter the correct password and check whether the connection can be established properly.
4. Disable Power Saving Mode
The power saving mode is intended to reduce battery consumption. Because Wi-Fi consumes a lot of power, connection stability can be affected if Power Saving mode is enabled. Try to disable Power Saving Mode that’s available on some Android devices. Some users may enable Power Saving Mode permanently, because they won’t to have longer battery life. However, this could cause some issues.
5. Use Right Password
Passwords are essential when connecting with Wi-Fi network. Without a proper password, you won’t be connected to any network. Your Android device will fail to authenticate the connection. Ask the administrator or get information from other sources to make sure that you have the right password.
6. Wi-Fi Sleep
If Wi-Fi connection keeps on dropping, check whether it happens after the phone goes to sleep. This capability may not be available on all Android devices and it’s added by phone manufacturers.

7. Check Ad-hoc and Hidden Network
Sometimes, your Android devices fail to connect automatically. This could happen if you are trying to connect to an Ad-hoc network. Many Android smartphones and tablets are not designed to connect to an Ad-hoc network, but they will work well with regular access points. Some networks can be purposely hidden. By default, Android devices don’t support Ad-hoc networks. However, you can use “wpa_supplicant” patch to connect with these networks. Before patching the “wpa_supplicant” file, make sure that you have backed up the original file.
Hidden networks are not meant to be discovered by unauthorized individuals. You need to ask administrators to know the SSID name, security method type and password. If the credentials are correct, you should be able to get full connection.
8. Disable Smart Network Switch
This feature is found in some Samsung Galaxy models. Because Samsung is the most popular manufacturer of Android devices, it’s valid to include this solution here.

9. Check Third Party Apps
Some third-part apps may cause conflicts and your Wi-Fi connection may not work properly as a result. Check whether the problem occurs after you download an app. If so, try to disable or uninstall the app. In rare cases, the problem can be resolved by updating the app. Apps that control Wi-Fi connection may potentially cause issues.
10. Check Date and Time
Date and time inaccuracy happens when you move between time zones quickly, especially when you fly with an airliner often. In order for the Android device to get proper connection, make sure that it has compatible date and time with the server. Go to the settings menu of your phone and adjust date and time appropriately.
11. Flush Wi-Fi Direct Cache and Data
Wi-Fi Direct is a practical feature, but it could interfere with normal Wi-Fi connection. After a period of use, it will accumulate cache and data, which could cause problems. Follow these steps:
- Go to Settings> Applications.
- Locate and tap on Wi-Fi Direct.
- Tap on Clear Data and Clear Cache buttons.
- Restart your phone; verify that the problem has been resolved.
The above mentioned solutions should resolve most problems associated with Wi-Fi connection on Android devices. If none of the above solutions works, you may need to take a more drastic action.

Go to Settings and the Backup and Reset. Tap on Factory Data Reset and wait for the process to complete.
