iOS 11 can't connected to unsecured network??

Do I need to add an invalid DNS server IP everytime when I connect to the unsecured network? Very troublesome!

Thank you. It worked

Are you scam bot or something? Did you read my answer? There was no internet at all at Starbucks that was the issue for me. Is there any admin checking this post?

this really did work after months of calling Apple and Verizon. I tell you mo more updates for awhile. Shame on Apple for not being able to help me the first time I called.

Same problem here on iPad Pro and iPhone 6. The public and guest networks where I work normally open a browser window where you agree to terms and conditions etc. Since iOS 11, the WiFi network connects normally then the connection drops a couple of seconds later. You can't force a browser window as the connection is gone by then.

I have moved everything back to 10.3.3 for now. What a disaster 11 has been so-far. WiFi issues, no voicemail, drained battery and frequent freezes.

I FINALLY HAVE A SOLUTION.

At least a solution that worked for ME. I spent two nights researching all over the internet and getting deep into the settings on my phone so I could load the Guest WiFi login page at my job and finally be able to use the Wi-Fi.

I kept getting the “unsecure network” page and couldn’t navigate through it. Nothing seemed to work. What worked for me?

FIRST, click the “i” next to the Wi-Fi network you’re trying to login to, and be sure both “Auto-Join” and “Auto-Login” are toggled OFF. Now, for the solution.

DOWNLOAD THE FIREFOX BROWSER. This browser, unlike Safari, allows you to to push through the security warning and visit the page anyway. Type in the address for the Wi-Fi login page or simply type in “captive.apple.com” into the search bar. You’ll get the same type of page as Safari, saying how it is an unsecure network. But unlike Safari, you’re able to click “visit site anyway”. And that’ll take you to the normal site where you can login to the Wi-Fi network.

It worked for me, I hope it works for all of you!

The whole point of captive.apple.com is to determine if the iOS device has a connection to the Internet. If it does not connect to captive.apple.com iOS displays whatever page the local network uses to capture login information. So if the network has HTTP login as a requirement the connection to captive.apple.com should not be allowed.

You haven't said what kind of network you are trying to connect to or what happens when you try. That makes it very difficult to help you. In general:

• Go to Settings/Wi-Fi and turn off "ask to join networks" - it just complicates things.
• If it is an unsecured network that does not require logging in it should just connect. You should not have to enter any information at all. If it doesn't connect go to Settings/Wi-Fi and tap on the i next to the network name, then tap "forget this network" and try to connect again.
• If it requires login (e.g., xfinity, cablevision, etc) when you connect after a short while (15-30 seconds) it should display the login page. If it doesn't, forget the network as explained above, then try again. You may have to do this each time you connect, depending on
• You should ignore the configure IP and configure DNS; these should be filled in by the network automatically. If you try to override them most likely it won't work at all.

My home network is not secured, My iPhone has no problems at all when connecting. Nothing special is required to connect, your phone must be the source of the issue, take it to an Apple Store for diagnosis.

First, this is a public forum. It is a very bad idea to post any personal information in a place where 5 billion users of the Internet can see it and vacuum it up to add to spam lists.

No problem here. Connects to unsecured networks the same as it always has. Try forgetting the network, then try again.
