My wife has an iphone 6s plus. We have a community gym with free Wi-Fi. However there is a pass code gate i.e. you have to login every time by entering the pass code in the browser. I’m an android guy through and through. I have absolutely no issue getting on the gym Wi-Fi. As soon as my phone detects the signal, it gives me the ‘Login to xxx Wi-Fi’ (see attached screenshot). I click on it, a browser window opens, I enter the pass code and voila. Hail Android. My wife’s phone however is such a pain. It does NOT give any kind of prompt. The network SSID shows in the list, it connects with it when you click on it, but then nothing. It does not give any prompt for the 'login to network' or something. I don't even know how/where do those prompts show up in iOS. I try to trigger it manually by opening a webpage in safari hoping for the passcode window to show up, nothing. It keeps pushing me to connect to the LTE. I don’t know anything about iOS. Is there something I need to do? How do I get the phone to tell me it needs a pass code to get on that particular network?
