As it turns out, the Xbox 360 is a lot older than I thought. I upgraded to AT&T Fiber for my internet, and that replaced my old router with one directly from AT&T. I thought nothing of it, and everything worked as expected for everything I used. What I didnt realize was that it automatically merged my 5Ghz and 2.4Ghz networks into one band. For most things, that wasnt an issue, but apparently, it a problem for my Xbox 360. I found out the hard way that the Xbox 360 cant connect to 5Ghz...
