If your Android phone shows the message “IP Address Could Not Be Obtained” when connecting to WiFi, it means your device is failing to get an IP address from the router. This problem happens on Samsung, Xiaomi, OnePlus, Oppo, Realme, Vivo, Motorola, and Google Pixel devices.
The issue may come from your phone settings, router problems, IP conflicts, saved network corruption, or DHCP failures. This guide gives you every working fix step-by-step.
What Causes the “IP Address Could Not Be Obtained” Error?
Typical causes include:
- DHCP server failure (router not assigning IP)
- Incorrect network configuration on Android
- Corrupted WiFi settings
- IP address conflict with another device
- Weak WiFi signal
- Router overload
- MAC filtering enabled
Try each fix in order.
Fix 1: Restart Your Phone
A simple reboot clears temporary WiFi configuration errors and refreshes network processes.
- Hold the Power button
- Tap Restart
After rebooting, try connecting again.
Fix 2: Restart the Router
If the router’s DHCP server crashes, it cannot assign an IP address.
- Unplug your router for 30 seconds
- Plug it back in
- Wait until all lights stabilize
Try connecting again.
Fix 3: Forget the WiFi Network and Reconnect
Corrupted saved WiFi settings can block IP assignment.
- Go to Settings → WiFi
- Select your network
- Tap Forget
- Reconnect and enter the password
Fix 4: Turn Airplane Mode ON and OFF
This resets network chips temporarily.
- Swipe down Quick Settings
- Turn ON Airplane Mode
- Wait 10 seconds
- Turn it OFF
Fix 5: Switch Between 2.4GHz and 5GHz
Some phones connect better to 2.4GHz, while others prefer 5GHz.
- If you’re on 5GHz, try 2.4GHz
- If you’re on 2.4GHz, try 5GHz
This often fixes IP assignment problems.
Fix 6: Disable MAC Address Randomization
Some routers reject randomized MAC addresses.
- Go to Settings → WiFi
- Select your network
- Tap Advanced
- Set MAC address type to Phone MAC
Fix 7: Assign a Static IP Address
If DHCP is failing, setting a fixed IP can bypass the issue.
- Go to Settings → WiFi
- Select your network → Advanced
- Change IP settings to Static
Enter this:
- IP address: 192.168.1.150
- Gateway: 192.168.1.1
- DNS1: 8.8.8.8
- DNS2: 8.8.4.4
Fix 8: Reset Network Settings
This resets WiFi, mobile data, and Bluetooth configurations.
- Open Settings
- Tap System
- Tap Reset Options
- Select Reset WiFi, Mobile & Bluetooth
Reconnect after the reset.
Fix 9: Reduce the Number of Devices on WiFi
Routers with low capacity may refuse new devices.
- Disconnect unused phones, TVs, tablets, etc.
- Restart the router
Fix 10: Turn Off Battery Saver
Battery saver mode can interfere with WiFi performance.
- Go to Settings → Battery
- Turn off Battery Saver
Fix 11: Disable VPN
VPN apps sometimes block WiFi authentication.
Turn OFF your VPN and try connecting again.
Fix 12: Check Router Security Settings
Your router may block your device using MAC filtering.
- Log in to your router (192.168.1.1)
- Go to Security or MAC Filtering
- Disable MAC filtering
Fix 13: Change Router Encryption Type
Some phones fail to connect to WPA3 networks.
- Open router settings
- Set WiFi security to WPA2/WPA3 Mixed or WPA2
Fix 14: Update Your Phone Software
WiFi bugs are often fixed through system updates.
- Go to Settings → Software Update
- Download & install updates
Fix 15: Update Your Router Firmware
Old firmware can cause DHCP errors.
- Open router admin panel
- Check for firmware updates
Fix 16: Factory Reset Your Router
If nothing works, reset the router.
- Hold the reset button for 10–15 seconds
Set up your WiFi again afterward.
Fix 17: Try a Different WiFi Network
Connect to a hotspot or neighbor’s WiFi to check if the issue is with your phone or router.
Conclusion
The “IP Address Could Not Be Obtained” error usually comes from router DHCP issues, WiFi corruption, or incorrect configuration. Following these steps will fix the problem in most cases. If all else fails, test another router or contact your internet provider.
