Use static IP address instead of DHCP
DHCP, or Dynamic Host Configuration Protocol is the default IP address assignment for the Wi-Fi settings on many devices. Whereas DHCP can cause IP address conflict during the dynamic IP address assignment. So, you’d better change “DHCP” to “Static” to see if the authentication error persists.

Step 4: Note down the static IP address fields and wipe off all the fields. Punch it in again and then save it.
Check carefully for duplicate Wi-Fi names before you connect
Perhaps, you might connect to a WiFi with a similar name. There are good chances that some users do not modify their WiFi network name and possibly, your neighbor may have the same WiFi network, service provider. Therefore, ensure you connect to the correct WiFi network.

After you reset a network connection, if still getting issues regarding the authentication of the network, you need to modify the connection. In this technique, you will be changing the IP settings on your phone to alter the way it establishes a secure connection. You can do it by following these steps.
