How to fix my iphone? It won't connect to any Wi-Fi?

It says its on but when I see the top left corner it still says 3G and now the Wi-Fi symbol… Help! I'm using up all my mobile data

Try turning the Wi-Fi on and off several times in quick succession.

Do the same for aeroplane mode.

Try manually typing in the name of the network you're trying to connect to.

Try turning the modem on and off.

  • My Wi-Fi won't connect on my laptop but will connect to my other devices (an iPhone and iPad)? I have a MacBook Air. Sometimes it does connect but other times it just won't. It takes ages connecting and then in the end comes up with the exclamation mark or is just blank. Is this a problem with my laptop? I've tried researching the problem but have found nothing.
