Fix Error: Wifi Keeps Disconnecting On Android

Wifi Keeps Disconnecting On Android

If you connect your Android smartphone or tablet to Wi-Fi, you can enjoy the Internet without mobile data communication.

However, even if you can connect to Wi-Fi normally, it may be disconnected without notice, or it may become unstable due to repeated connection and disconnection.

This article will introduce what to do when Wi-Fi keeps repeatedly disconnecting on Android.

Method 1: Reboot the device

There may be a case where WiFi is automatically disconnected and connection and disconnection are repeated due to temporary system trouble in Android.

So first, restart your Android device and see if the problem goes away. Rebooting the device will reset all system errors and allow you to reconnect to WiFi.

If restarting your Android device does not resolve the WiFi issue, proceed to the next solution.

Method 2: Bring your device closer to your WiFi router

The signal strength of WiFi becomes weaker as you move away from the WiFi router, and the connection becomes unstable.

Therefore, if the Android device and the WiFi router are far apart, check if the WiFi is disconnected while keeping the device close.

If moving the device closer to the WiFi router solves the problem, the WiFi signal may be weak. Move the location of the router or consider installing a WiFi repeater.

If the WiFi is disconnected even if you bring the device close to the WiFi router, proceed to the next solution.

Method 3: Delete and reconfigure the WiFi connection settings

There may be a case where the connection with the WiFi of the Android device is automatically cut off due to some problem in the WiFi connection settings.

Therefore, deleting the WiFi connection settings and then reconfiguring them may solve the problem. To reconfigure WiFi, follow the steps below.

  1. Launch the “Settings” app.
  2. Tap “Network and Internet (or Connection)“.
  3. Tap “WiFi“.
  4. From the WiFi list, tap or long-press “SSID of the WiFi problem“.
  5. Tap “Delete settings“.
  6. Return to the WiFi list screen and tap “WiFi SSID“.
  7. Enter the WiFi “password” and tap “Connect“.

With the above procedure, you can reconfigure WiFi. After resetting and connecting to WiFi usually, check if the connection is not disconnected.

If you continue to connect and disconnect after resetting WiFi, proceed to the next solution.

Method 4: Maintain a sleeping WiFi connection

There may be cases where the connection and disconnection are repeated because the Android settings are set to disconnect the WiFi connection during sleep.

Method 5: Turn off the WiFi auto-selection feature

Some Android devices have a feature that automatically selects the best WiFi. Due to this function, WiFi may be connected or disconnected.

Therefore, check the setting of the WiFi automatic selection function, and if it is enabled, try disabling it.

To turn off the WiFi auto-selection feature, follow the steps below.

  1. Open “Settings“.
  2. Tap “Network and Internet“.
  3. Tap “WiFi“.
  4. Tap “WiFi Assistant“.

Method 6: Turn off the function to switch to mobile data

Depending on the Android device, a function to automatically switch to mobile data communication when the WiFi signal is weak is implemented.

Due to this function, it is possible that the WiFi connection will be disconnected at an unintended timing.

Therefore, please disable the function to switch to mobile data and see if the WiFi problem is improved. The specific procedure is as follows.

  1. Open “Settings“.
  2. Tap “Network and Internet“.
  3. Tap “WiFi“.
  4. Tap “WiFi settings“.
  5. Change the “Switch to mobile data” switch to “Off“.

Depending on the model, the names such as “automatic network switching” and “smart network switching” may differ.

If you can disable the automatic connection of unnecessary WiFi or delete the setting, please check if the problem of WiFi disconnection has been solved.

Method 8: Cancel WiFi power save mode

If you are using a Galaxy model, WiFi may connect and disconnect repeatedly due to the WiFi power save mode.

Therefore, please cancel the power save mode of WiFi and check if the problem is solved. To cancel the WiFi power save mode, follow the procedure below.

  1. Launch the “Phone” app.
  2. Enter * # 0011 #.
  3. When the MENU is displayed, tap “WiFi“.
  4. Switch “WiFi Power Save Mode” to “OFF“.

You can cancel the WiFi power save mode by following the above procedure. If you can change the settings, please check if the problem that WiFi is cut off is solved.

Method 9: Switch the WiFi frequency

Depending on the environment, switching the WiFi frequency (2.4GHz / 5.0GHz) may improve the problem of WiFi disconnection.

2.4GHz WiFi is strong against obstacles such as walls, and 5.0GHz WiFi is strong against radio wave interference.

Therefore, try connecting to a WiFi with a frequency different from the one you are currently connected to. However, to try this method, your WiFi router must support multiple frequencies.

To switch the WiFi frequency, follow the procedure below.

  1. Open “Settings“.
  2. Tap “Network and Internet (or Connection)“.
  3. Tap “WiFi“.
  4. When the WiFi list is displayed, tap “Another WiFi that starts with the same SSID as the connected WiFi“.
