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 1: Head to the “Settings” of your Vivo Y27s and then opt for “Wireless and Networks” followed by “WLAN/WiFi”.

Step 2: Now, hit on the WiFi network that is showing “authentication error occurred”.

Step 3: Depending on your Vivo Y27s model, look for “IP Settings” and tap on it. Now, switch the “DHCP” to “Static”.

Step 4: Note down the static IP address fields and wipe off all the fields. Punch it in again and then save it.

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.

Reset the Wifi network

One of the easiest ways to fix the authentication problem of Wifi is to reset the network. To do this, you would be required to forget the respective network first and then connect to it again. This can be done by simply following these steps.

3. Afterward, turn on your Wifi again and tap to the network you wish to connect to. Simply provide the credentials and tap on the “Connect” button to reestablish the connection. This way, you can reset the network successfully.

Modify network connection

If the above solution won’t work, then you would be required to walk the extra mile to fix the Vivo Y27s Wifi problem. 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.

1. To start with, visit your phone’s Settings and open the Wifi page.

2. This will display a list of all the Wifi networks that are associated with your device. Just long-tap on the Wifi network that you wish to modify. It will open another pop-up window. From here, tap on the option of “Manage network settings”. Sometimes, users also get an option of “Modify network settings” here as well. Simply select it to proceed.

3. It will display basic information related to your Wifi network. Just tap on the “Show advanced options” button to access more options related to the network setting.

4. From the IP Settings menu, change the field from DHCP to Static. This will let you establish a static connection between your device and the router.

5. As soon as you will change it to static, you will get different fields related to your network’s IP address, gateway, DNS, and more. Simply fill these fields and tap on the “Save” button once you are done.

Now, try to connect to the Wifi hotspot again. You would be able to overcome the authentication problem of Wifi.

Change Network Security Type

It has been observed that, when we connect to Wifi, our device chooses a wrong security type. This clashes with the default security protocol of the router and authentication error occurred due to this. If your device is facing the same issue, then it can be fixed by simply changing its security type. To do this, follow these instructions:

1. To change the security type of a network, you need to “Add the network”. If you already have the Wifi network saved, then simply forget the network by following the above-mentioned tutorial.

2. Now, turn on your device’s Wifi and tap on the option of “Add network”. Here, you would be asked to give a network name and select the security type. To manually select it, tap on the “Security” option.
