The poor soul had their wifi on at the same time. Another person with a sore head didn't know to disable it and reboot.
Hope this helps,
I currently live in a community scholarship house on my college's campus, and the Wi-fi is less than satisfactory when it comes to certain things, like playing online games and downloading files. My ethernet works every now and then, but for the most part it never does work. The part about that that doesn't really make sense is the fact that when I plug the ethernet into my Xbox 360, it works fine, and when my roommate uses his ethernet cable, he gets internet just fine. I even tried using his ethernet cable in place of mine, and it still doesn't work. Does anybody know what the problem may be?
