Hi
I've been having trouble the last few days with the shared WiFi in the student accommodation I'm currently residing in.
It's a public, open connection which then requires you to sign in on the browser with a username and password as per the screenshot below. This has previously worked just fine and is working on other, non-Windows devices such as my iPhone and PS4. In addition to this, I believe this problem has reared its head ever since I agreed to let some kind of Windows 10 system alert change my security settings for an impending update or something and I'm unsure what to do. Every time I attempt to sign in it instantly gives me the 'Authentification failed' box. I've even tried my girlfriend's login so I'm almost sure it's an issue with the laptop itself or the security settings.
I've also tried to system restore to get around the problem but that has also failed twice.
I hope someone is able to help and thanks in advance.
