Restart your device
Restarting your device should be the first step you take towards fixing any network issue. A simple restart resolves any background glitches and clears any corrupt files in the cache. To restart your smartphone, simply long-press the side key or press and hold the side key and volume key to access the power options. On your laptop or PC, click on the Windows icon and select ‘Restart’ from the power options.
Restart the router
If the issue persists after restarting your device, try restarting your router as well. To restart the router, turn off the power switch from the wall outlet that it is connected to. Wait for a couple of minutes for the router to restart, then connect your device to the WiFi and see if it works.

Step 3: Tap on IP Settings and select Static.
Step 4: You will need to change the IP address. Select an IP Address within these ranges:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255

Change your router’s network encryption
Some network encryption methods can keep the WiFi from properly connecting to your device and may throw up the ‘Failed to obtain IP address’ error. To fix this, simply change your router’s network encryption method. Go to your router’s web interface and select ‘Encryption Method’. If the encryption method is set to AES or TKIP, change it to WPA2-PSK. The WPA encryption type is compatible with most Android devices.
Flush the DNS cache
The DNS cache keeps a record of the websites you have visited in the past. It gives your device instant access to the IP address of the website you’re trying to visit. The DNS cache is prone to corruption. This can lead to the ‘Failed to Obtain the IP Address’ error on your Android phone. Clearing the cache will solve this problem.
Step 1: Launch Google Chrome on your Android phone and type the following command in the address box:
chrome://net-internals/#dns
Step 2: Tap on Clear host cache.
Turn off the MAC filter
If you’re using a friend’s WiFi network, they may have enabled the MAC filter on their network. A MAC filter gives Internet access to the devices with their MAC addresses on the whitelist. You can either ask for your device’s MAC address to be added to the whitelist or suspend MAC filtering altogether. This can be done under the ‘MAC filtering’ section on the router’s web interface.
Reset the Router
If you’ve tried all of the fixes on this list but are unable to fix the issue, you may want to reset your router. This will get rid of all the custom settings and reset it to factory settings. Record all the essential details like IP address, DNS address, and login credentials before resetting your router. To reset your router, simply press and hold the reset button at the back until it shuts down and starts again.
Reset Network Settings
Resetting the router didn’t work either? Try resetting your smartphone’s network settings. Here’s how.
Step 1: Go to Settings and select General Management.
Step 2: Scroll down and select Reset.
Step 3: Tap on Reset Network Settings.
Step 4: Select Reset Settings.
Step 5: Enter your PIN to confirm your selection.
