so annoyed rn has anyone dealt with 0x80a40019?? my Xbox One can't sign in since i changed my router:

Can't connect to the server.
The server may be busy, or your network connection
may have been lost. Try again later.
Connection test: Internet Failed
the network test says Im connected to the internet, but the sign-in still fails. im on an apratment building network... my profile picture just sits there with a spinner and then gives up, id really like to avoid fcatory resetting, i have a lot installed.
ive already tried the obvious stuff: restarting everything, checking cables, waiting an hour, it still fails, what should i look at next?
