In the last few days, every time I open a browser on my iPad I get a message about captive.apple.com and when I press "done" it goes away. What I want to know is how to stop it appearing in the first place.
Also every time my iPad times out and needs me to type my pin to get in, I find the wifi has disconnected (it didn't use to). To get back online I go to settings, touch the wifi connect to my router and it shows that same login screen.
I have not set this up, it's just appeared.
Another annoyance is I'm getting a webpage from my isp about setting up my broadband popping up at random if I open a new tab that links to a different page.
I suspect these things are related, so how do I stop them?
Further: my wife tells me it's happening on her iPad too, and the webpage from the isp popup also appears on the networked desktop pc while using any browser
