Your Android phone wants to join Wi-Fi. The router says, “Sure, come in.” Then something gets weird. Your phone gets stuck on Obtaining IP address or shows IP configuration failure. Rude, right? Do not worry. This is common, and you can usually fix it in a few minutes.
TLDR: Android IP configuration failure means your phone cannot get a proper network address from the Wi-Fi router. Start by restarting your phone and router, then forget and reconnect to the Wi-Fi network. If that fails, set a static IP or reset network settings. Most of the time, one of these steps saves the day.
What Does “IP Configuration Failure” Mean?
Think of your Wi-Fi router like a hotel front desk. Your Android phone walks in and asks for a room number. That room number is the IP address. Without it, your phone cannot talk to the internet.
When Android says IP configuration failure, it means the router did not give your phone a usable IP address. So your phone stands in the lobby, holding its tiny digital suitcase, looking confused.
This can happen because of a router glitch, a bad saved Wi-Fi profile, weak signal, network crowding, or wrong phone settings.
1. Turn Wi-Fi Off and On
Yes, this is the classic “turn it off and on again” move. It works more often than it should.
- Swipe down from the top of your screen.
- Tap the Wi-Fi icon to turn it off.
- Wait about 10 seconds.
- Turn Wi-Fi back on.
- Try connecting again.
This gives your phone a fresh chance to ask the router for an IP address. Sometimes that is all it needs.
2. Restart Your Android Phone
Your phone may have a tiny network hiccup. A restart clears temporary bugs and refreshes system services.
- Hold the Power button.
- Tap Restart.
- If you do not see Restart, tap Power off.
- Wait a few seconds, then turn it back on.
After the phone starts, connect to Wi-Fi again. If it works, celebrate with a tiny victory dance. Optional, but recommended.
3. Restart Your Router
Your router may be tired. It has one job, but it still gets grumpy.
- Unplug the router from power.
- Wait 30 seconds.
- Plug it back in.
- Wait until the lights look normal.
- Reconnect your Android phone.
This can fix router memory issues and restart the system that gives out IP addresses. That system is called DHCP. You do not need to remember the name. Just know it plays “address manager” for your network.
4. Forget the Wi-Fi Network
Sometimes your phone remembers old or broken settings for a Wi-Fi network. Forgetting the network wipes those settings. Then you can reconnect like it is a first date.
- Open Settings.
- Tap Network and Internet or Connections.
- Tap Wi-Fi.
- Tap the network name.
- Tap Forget.
- Choose the network again.
- Enter the Wi-Fi password.
Make sure you know the password before you forget the network. Otherwise, the fix becomes a treasure hunt.
5. Move Closer to the Router
A weak signal can cause connection problems. Your phone may see the network but fail to complete the setup.
Move closer to the router. Try connecting in the same room. If it works there, distance or walls may be the problem.
Thick walls, metal objects, mirrors, microwaves, and even fish tanks can mess with Wi-Fi. Yes, fish tanks. The fish are not guilty. The water is.
6. Check If Other Devices Can Connect
Try connecting another phone, laptop, or tablet to the same Wi-Fi.
- If other devices connect, the problem is likely your Android phone.
- If no devices connect, the problem is likely the router or internet setup.
This quick test saves time. No need to blame your phone if the router is the real troublemaker.
7. Set a Static IP Address
If your router will not give your phone an IP address, you can give your phone one manually. This is called using a static IP.
Do this only if the easy fixes did not work. It sounds fancy, but it is not too scary.
- Open Settings.
- Go to Wi-Fi.
- Tap your network.
- Tap Advanced or the pencil/edit icon.
- Look for IP settings.
- Change it from DHCP to Static.
Now enter network details. These may vary, but a common setup looks like this:
- IP address: 192.168.1.50
- Gateway: 192.168.1.1
- Network prefix length: 24
- DNS 1: 8.8.8.8
- DNS 2: 8.8.4.4
Your router may use 192.168.0.1 instead of 192.168.1.1. If so, use an IP like 192.168.0.50. The first three number groups should match your router.
If this feels too techy, skip to the next step. No shame. Static IP settings are the broccoli of Wi-Fi fixes. Useful, but not everyone wants them.
8. Turn Airplane Mode On and Off
Airplane Mode shuts down wireless connections. Turning it off starts them fresh.
- Swipe down from the top of the screen.
- Tap Airplane Mode.
- Wait 10 seconds.
- Tap it again to turn it off.
- Try Wi-Fi again.
This is a quick trick. It can help when Android’s network system gets stuck.
9. Check the Router’s Device Limit
Some routers only allow a certain number of devices. If the network is full, your phone may fail to get an IP address.
This happens often in busy homes, offices, dorms, and cafés. Phones, TVs, tablets, cameras, speakers, watches, and game consoles all want a slice of Wi-Fi pizza.
Try disconnecting a few devices. Then reconnect your Android phone. If it works, the router may need a higher device limit or a reboot more often.
10. Change the Router Security Type
Some older Android phones do not play nicely with certain router security settings. This is less common, but it can happen.
Log in to your router settings. Look for Wireless Security. Use WPA2 or WPA2/WPA3 mixed mode if available. Avoid very old options like WEP. WEP is ancient. It belongs in a tech museum next to floppy disks.
If you are not comfortable changing router settings, ask the person who manages the network.
11. Reset Network Settings
If nothing else works, reset your Android network settings. This clears saved Wi-Fi networks, Bluetooth pairings, and mobile network settings. Your photos and apps stay safe.
- Open Settings.
- Tap System.
- Tap Reset options.
- Tap Reset Wi-Fi, mobile, and Bluetooth.
- Confirm the reset.
The wording may be different on Samsung, Xiaomi, OnePlus, Pixel, or other Android phones. Search Settings for reset network if you cannot find it.
After the reset, reconnect to Wi-Fi and enter the password again.
12. Update Your Phone
Software bugs can cause network problems. Updates often include fixes.
- Open Settings.
- Tap System or Software update.
- Check for updates.
- Install any available update.
Keep your phone charged before updating. Nobody wants a phone nap in the middle of a system update.
When Should You Call for Help?
Call your internet provider if every device has Wi-Fi trouble. Call your phone maker or carrier if your Android phone fails on every Wi-Fi network.
Also, if this happens only on school, hotel, or office Wi-Fi, the network may block unknown devices. You may need to sign in through a portal or ask the network admin.
Final Thoughts
Android IP configuration failure sounds like a scary robot problem. But it is usually simple. Restart things. Forget the network. Move closer. Try a static IP if needed. Reset network settings as a last big broom.
Most Wi-Fi problems are just tiny traffic jams. With these fixes, your Android phone should get its IP address and return to scrolling, streaming, and sending important messages like “lol” and “where are you?”
