So my sharing is on. No network bridge because that's never worked in the past. It's been working fine up until a few days ago, when it just stopped connecting.
I've reset my modem, I've tried doing both manual and automatic IP, and I've followed all of the suggestions that the xbox help section thing has offered.
I have no idea what to do now.
I'm using a wired connection, as I have an arcade (from like a gazillion years ago), and now the connecting cord isn't lighting up like it usually does.
I'm so lost.
