Solution 3: Use a static IP address on your mobile device
An IP conflict can also cause the Wi-Fi authentication problem. For this reason, we recommend using a static IP address instead of DHCP .
This protocol is responsible for automatically assigning IP addresses to the various devices connected to the router.
Very often, the DHCP protocol causes IP address conflicts. The solution would be to change " DHCP " to " Static " to see if the authentication error is resolved. To do this:
1. Go to your Android device's settings and select a network connection
2. Long press on the WIFI name you selected and then click on the " Manage network settings "
Show advanced options box to display the IP settings.
4. Click on static to configure your Android mobile's IP address to a fixed IP address
5. A new window will then appear displaying the IP address field. Note down, save, and then delete the information
6. Wait a few seconds, then enter the same information in the corresponding fields.
7. Finally, press " Save "
