Step 3: Depending on your Realme 12 Pro+ 5G 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.
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.
