I was running Lion 10.7.1 on my MacBook pro. Wireless connected without issues at school. The way wireless works at school is through an authentication page where you first select the WIFI and then open up safari and authenticate via username and password. After the update to 10.7.2, the page will not load at all. Check with school to see if there was any certificate issues, but they stated that nothing has changed. Tried different browsers Firefox, Chrome, but not luck. The page just pretends to load and it never does. The odd thing about this issue is that my friend is running Lion 10.7.1 and it works properly. So far there are three mac users w/ 10.7.2 and it is not working for them. So I am begining to think that the issue is related to 10.7.2. The computers are showing they have IP address just will not load login screen. Ideas ?
