Ok so I live in a Residence Hall at my college that recently changed their internet or something. The email saying they were going to change it said that a 802.1x window should open and to just type in my username and password but that window never showed up. I dont completely remember if I did that or not but whenever I try to set up Internet Sharing, my mac says "Your Internet connection cannot be shared because it is protected by 802.1X." Does anyone know how to fix this problem?
