Basically, the router assigns your device with an IP address whenever you connect to a Wi-Fi network. This comes in a chain of numbers, for example, 192.168.1.1, 172.18.256.1, or any numerical combination in similar formats. However, your phone might not always be able to get this address. Failing to obtain it will result in your phone not connecting to Wi-Fi.

You might experience the Failed to Obtain IP Address Error even with a Wi-Fi network your device has already connected previously. Moreover, it can happen to any Android phone user. There are different reasons for this; failing to obtain an IP address might be due to wrongly configured Wi-Fi settings, router bugs, or a software problem. In any case, the solutions are pretty straight forward as we already mentioned.

Sometimes, it is not because your Android phone lost its capability of getting an IP address. It may just be too slow in accessing a network. When it seems that the task is taking forever, your connection might also be unstable.

You may want to rethink your router placement or simply move near it. Try to use your Android phone while sitting next to the router so you can experience faster connectivity. It’s basically logic — distance equals speed. That is also why gadgets connected directly to a router can surf the web faster than devices far away from the unit.

 

2. Reboot Android Phone or Router

If it is unknown whether the phone or router is causing the Failed to Obtain IP Address problem, try restarting both first. A reboot reverts devices to a state free of minor issues and running data, so it is always part of troubleshooting tips you can find online. It may also help an Android phone or a router that is slowing down to function back to normal.

Rebooting an Android phone is a hassle-free task for anyone. Restarting can be done in three to five steps for most of the latest models. Moreover, there is no need to browse through menus. All that is required are a few button clicks.

4. Forget Network

The failure to obtain an IP address often happens for a short while so making the Android phone forget and reconnect to a network should work most of the time. Forgetting, in this context, means that the device will detect the network as if it was a first-time connection. As a result, you will have the phone rescan the network, and you will be asked for the password to connect to it.

5. Set Static IP Address

The IP address that the router provides your Android phone is dynamic so it may change and have problems. Fortunately, you can set the IP address on your own if you encounter the Failed to Obtain IP Address or other Wi-Fi connection errors.

The address you will be assigning to your device is called Static IP. That is fixed, unlike the one from your router. To proceed, you must make your Android phone forget the network beforehand, which you already know how to do.

Here are the steps to follow to obtain a Static IP after forgetting the Wi-Fi network:

1. Click on Advanced below the network information fields.

2. Select IP Settings.

3. Replace DHCP with Static by clicking the drop-down menu arrow.

4. Use a new number between 1 and 225 as the last digits of your current IP address, then tap Save.

5. Use a different number between 1 and 225 if what you used is already taken by a device or not working.

 

6. Swap AES and TKIP Modes

A router can have minor issues with the network encryption mode that lead to the Failed to Obtain IP Address error on an Android phone. When this is likely the cause, you have to try an alternate mode as a solution.

Choose the right encryption type to switch to. Routers often have AES and TKIP encryption modes. AES is an acronym for Advanced Encryption Standard, while TKIP means Temporal Key Integrity Protocol. Although AES is more popular globally and considered stronger and faster than TKIP, both can still effectively protect a Wi-Fi network from breaches or hacking. Given that, choosing any of the two will work for your router.

To swap modes and fix the IP address issue, find the encryption settings of your router. Security settings and configurations are typically available on the router’s webpage. The procedure to change those will vary depending on your router provider.

Here are general instructions that will help you replace the encryption mode in use:

1. Visit your router’s webpage.

2. Login using your default or customized credentials.

3. Look for the Wireless Settings menu.

4. Click on the Security tab if available.

5. Select the encryption mode you prefer between AES and TKIP.

 

7. Deactivate MAC Address Filtering

The MAC address is as important as an IP address when it comes to Internet access. When relevant settings are toggled, Wi-Fi connectivity might also be affected.

MAC or Media Access Control is a physical or local device identifier, which is different from an IP address that is a global one. An example of a MAC address is 00:0a:97:9c:68:17 or any combination of letters and numbers in the same format. Part of the series is the device manufacturer ID.

When MAC Address Filtering is activated on your router, it will prevent a specific device from accessing certain networks. This is why checking the MAC Address Filtering feature is one of the best solutions when your device fails to obtain an IP address.

You can deactivate MAC Address Filtering on your router in a few steps:

1. Access your router’s homepage via the web.

2. Sign in using your default or customized login name and password.

3. Look for the WLAN, Access Control, or Advanced option.

4. Click on the WLAN MAC Filter or a similar tab.

5. Select the Disable option for the listed addresses if any.

6. Click Save or Apply for the router to implement the changes.

Note that the procedure may also vary slightly depending on your router brand’s webpage. Also, not all routers have the MAC Filtering capability. You must check the official support page of your router provider besides the guide above so you can navigate the interface easier.

 

8. Toggle Airplane Mode

Airplane Mode is a mobile device feature that is useful even if you are not on a flight or trip. It prevents the gadget from interfering with aircraft signal transmission and wasting battery power.

Airplane Mode disables your Android phone’s mobile data, Bluetooth, and Wi-Fi functions. Once switched off, it will result in the router and mobile device rescanning and reestablishing a connection. Airplane Mode works like a reboot but is specifically for Wi-Fi; therefore, this may solve the Failed to Obtain IP Address error even if the cause is unknown.

There are two ways to toggle an Android phone’s built-in Airplane Mode: via the Settings menu or an icon shortcut. Both methods will take you just a few seconds to finish.

 

Method 1: Through the Menu
