I have a MacMini 2012 running OS X 10.8.2. Since I have had it, I have been operating on a WPA Personal Wi-Fi connecting with no problems whatsoever. I happened to log on to a WEP Network today and ever since, it will not connect to the net. I have 6 other computers on the same network and they all work swimmingly. It shows that it is connected but Safari won't connect. I tried making a new location in the network settings like I saw on some posts and nothing! Please help!
