Sharing iPhone WiFi connection

Solution 1:

It can be found under Settings → Personal Hotspot. Password is also set there. Settings → Cellular, Personal Hotspot is also the same setting. When you turn it on, it asks if you want to turn on Wi-Fi and Bluetooth, or, USB only.

If USB is connected, one can turn on Personal Hotspot from Control Centre, it will automatically use USB to share cellular data. In Control Centre, holding down (force touch/ 3D Touch) the square block with Wi-Fi, Cellular data etc reveals two extra options of Airdrop in the bottom left and Personal hotspot in bottom right.

If USB is disconnected, Wi-Fi should remain in "on" state, but no new connections should be allowed, i.e. white state, not blue in control centre. Same for Bluetooth. This lets you share mobile data. But you cannot share iPhone's Wi-Fi connection using Wi-Fi or Bluetooth or USB.

• Does personal hotspot always use cellular data?
• How to check if iPhone is sharing Wi-Fi network or Cellular data via hotspot?

At times, when connected to USB, iPhone can prompt for passcode for allowing computer connected to access data on the iPhone.

Keep in mind on windows PC you need to have iTunes installed for it to trigger to ask that permission to 'Trust the PC' on the phone when connected via USB.
