    Hi

    Take a look at this Apple Support article:

    https://support.apple.com/en-us/HT204051


    Reset your network settings.


    Settings - General - Reset - Reset Network Settings


    Reset your device. This won't delete your data stored on the phone.

    • Press and hold the Sleep/Wake button
    • Press and hold on the Home button
    • Keep holding both buttons until the display turns off and back on with Apple logo on it.


    Alternatively, you may go to Settings - General - Reset - Reset All Settings

    I see. If it doesn't help, you can try to switch on Airplane mode: temporarily switch on Airplane mode and then turn it off to see if the Wi-Fi issues be solved. Swipe up from the bottom to bring the Control Center > Toggle Airplane mode on for 10 seconds > Toggle it to off.

     

    This step can also help you: disable Wi-Fi Networking in System Service:

    Go to Settings, choose Privacy, tap Location Services, tap System Services, turn off Wi-Fi Networking. This does not turn off wireless networking in iOS entirely, only relates to your location being used for Wi-Fi Networking.

     

    As a final step:

    Change DNS Settings to Google: Settings > Wi-Fi > Tap on the (I) button to the right of the router name, then scroll down to DNS and tap the numbers, then enter "8.8.8.8".

    Thanks for your help....

    The first two options did not work....

    Last option you suggested, I can not try this out... As my device is not detecting any network (Router Name)

    Anyways thanks a lot for your timely and fast response

    I wish it would help but... maybe it's better to make an appointment at the Apple Store cause it can be a hardware issue.
