How to fix the “Failed to obtain IP address” error on Android

What does “Failed to obtain IP address” message mean?

The “failed to obtain IP address” error appears when a user may try to connect to a Wi-Fi network. A router assigns an IP address for any connecting device. Your device must obtain this address to be able to connect to a router. This message means that there is an IP configuration failure, and the user is unable to join a Wi-Fi network.

Here are the most frequent reasons for that:

  • Poor Wi-Fi signal. In this case, you should reduce the distance between your device and the router;
  • Your device does not operate properly with the set encryption method;
  • Problems with your router. If you're still trying to connect, it could be either its malfunctioning or configuration issues;
  • Enabled MAC filtering. Your address might not be whitelisted;
  • Software or configuration problems of your device.

6 ways to fix the “failed to obtain IP address” error on Android

Reconnect to a network

It is the first and simplest method you should try. When you do this, the router forgets the previous attempt and initiates a new process to assign you an IP address. If the issue is due to temporary interference, this should help. You can do this by following these steps:

1. Go to Settings;

3. Click on Wi-Fi;

4. Tap on and hold the selected Wi-Fi network, and then choose Forget Network.

After this, log in to this network as usual.

Assign a static IP address to your device

If your device cannot obtain an IP address automatically, you may try to assign one manually. However, this workaround is temporary as you will need to reconfigure your network settings manually, turn off your Wi-FI, and restart your phone each time you connect to a different network.

To assign an IP, you should:

    1. Go to Settings
    2. settings icon on android screen
    3. Tap on Connections
    4. connections option in settings
    5. Choose Wi-Fi
    6. wifi option in connections
    7. Tap and hold the selected Wi-Fi network, and then choose Forget Network
    8. forget network option in wi-fi settings
    9. Try reconnecting to a network and click Advanced under the password field
    10. network options advanced section
    11. Then tap IP Settings drop-down menu
    12. IP settings in advanced section
    13. Select Static
    14. Choose static instead of DHCP
    15. In the IP Address field, change the last digit of your IP address to any number between 1 to 225
    16. field to insert IP address
    17. Click Save and retry the connection
click save to save new IP settings

Note that you should know the IP address of your router to do this. You may check how to find it on Android here. Sometimes, it is also displayed on the router.

Restart your router or mobile device

This is a pretty straightforward method. It should work if the reason is some software glitch or conflict. Each router model has its control interface, so the process of restarting it might differ. Usually, you should enter the router's IP in the browser to access the control panel and restart it there. To restart your Android phone, hold the power button for a few seconds, and then choose Power Off.

Change the encryption type

WPA and AES encryption methods sometimes do not work properly with some Android devices. You might try switching between them. As with the previous method, you will find these settings in the router's web interface. They will most likely be filed under the security section. Look for Encryption Mode, Encryption Method, or similarly named field and try changing it. After this, reconnect to a network as per the first method.

Turn off MAC filtering

MAC address is a unique number assigned to computer hardware connecting to a network. MAC filter allows only whitelisted MAC addresses to connect to a network. Your address might not be among those. To disable MAC filtering, log in to your router's interface via a web browser and look for the Disable/Enable MAC Filtering or similarly named section.

Turn flight mode on and off

The flight mode restarts phone settings, so if the issue is some software disruptions or similar, this method might help. To enable it, swipe down from the top of the screen and tap the Airplane Mode button.
