Re iPhone 4 I am unable to turn phone on to pick up Wi-Fi?

Customer Question

Re iPhone 4 I am unable to turn phone on to pick up Wi-Fi? If I go into general settings it shows Wi-Fi as being off, when I touch the screen it goes to a Wi Fi screen which shows a colourless empty barrel but when I touch the barrel nothing happens? I went into CarPhone Warehouse yesterday and they couldn't get it to do anything either. Any help would be appreciated?

Thank you for your question, my name is Richard and I look forward to assisting you.

Please note, click on Reply to Expert to reply to me, a rating is only needed when we are finished.

Can you do this as the first step please.

Go to Settings, General, Reset, Reset network Settings.

Once complete, then hold the power and home button for about 10 seconds, until you see the Apple Logo, and release.

Let it restart and then try to connect to your wifi network.

Let me know the results please

Thank you

Sorry, have tried advice twice but it has not made any difference

Do you have iTunes installed on your computer?
Customer: replied 4 years ago.

Yes but only since last night. Carphone Warehouse explained that I needed an update which hadn't been done, this was because it needed Wi-Fi to do it and my phone didn't have it! They thought this lack of an update may have been the problem so explained how I could download iTunes onto my computer and then do software update. Updated last night, didn't make any difference.

Expert:  Richard replied 4 years ago.
ok, it is not due to any updates.

It is either the firmware or the wifi antenna that has faulted.

We are going to reinnstall the firmware. To do this, first connect the iPhone to the computer, and open iTunes.

Then in iTunes, click File, Devices, Backup and do a backup of your phone.

Then disconnect the phone from the computer.

On the phone go to Settings, General, Reset, Erase all content and reset settings.

This will reinstall the firmware.

Let this complete and when it has, setup the phone like when you first received it.

Tell me if Wifi is then working please.

Have gone into iTunes but when I click file I get four greyed out options ie. Sync, Transfer purchases, Back up & Restore from back up -------

none are in black and do not respond?

Expert:  Richard replied 4 years ago.
The phone is connected to the computer correct?

Customer: replied 4 years ago.

As you have probably guessed I am not very knowledgeable in this area. Apologies, have now connected to computer and will retry.
