Xbox won't connect to internet

I live in a school and use it's internet, the School's has a wifi filter/blocker which I need to sign into with a username and password as well as the normal internet password. On my computer or iPad when using the internet a screen pops up with the option
to sign into the filer (called fortiguard) which I sign into using my username and password but the Xbox one doesn't give this option. It simply asks for my internet password and than says it it can't connect

Heya!

If you are having issues getting that to sync with a wireless connection we suggest setting up a wired connection at least until the profile is activated properly.

Let's also have you test that connection with the troubleshooter for
network connections.

Once you are reconnected to Live, let's have you
remove your profile and
power cycle the console to be sure that your account is synced.

Post back and let us know how that goes!

 

Try opening up Edge and browsing the internet on the Xbox, this should add your xbox to the router and allow it to access the internet.
