I just configured my home network with several computers, and access point, using the same names and passwords i had on the initial computer. When I shut down and rebooted, I was prompted with a different-looking message box asking for my username and password. I have tried every combination of names and numbers I have ever used throughout this life and the previous lives I've endured, all without success. I have tried rebooting using safe mode, manual boot with a disk, but that window keeps popping up.
