Solution 3: Use a static IP address on your mobile device

IP adress

An IP conflict may also be causing the WIFI authentication issue. For this, we advise you to use a static IP address instead of DHCP .

The latter is in fact a protocol whose role is to automatically assign IP addresses to the different devices connected to the router.

Very often, this DHCP protocol causes IP address conflicts. The solution would therefore be to change “ DHCP ” to “ Static ” to see if the authentication error will be resolved. For that :

1. Enter the settings of your Android device 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 the IP address of your Android mobile as fixed IP

5. A new window showing the IP address field will then appear. Write 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
