Why does my iPhone keep losing public WiFi networks?

Thanks for reaching out Neville Goodman1,

It sounds like you're having some trouble using public Wi-Fi compared to when you are using your own private networks. We can help.

What you might be running into is a captive network that is requiring you to connect manually. Checkout these steps to Use captive Wi-Fi networks on your iPhone or iPad.

Hope that helps.

Take care.

Hey Neville Goodman1,

That is because you’re using captive Wi-Fi networks and isn’t unexpected, as they often times require additional authentication. If you have further questions about why this particular captive network is requiring this, you’ll want to ask the network administrator or whoever manages the network at that location.

We hope this helps out.

Take care!
