Hello peoples, so, here is the deal i hope someone can help. I have the 2.4ghz aluminum macbook, late '08. I go to a community college that is pretty large, compared to community colleges. I have full bars most of the time at school but about 50% of the time there is no connection. On mozilla i get an error to contact the server administrator and i just get a no network on safari. I installed windows 7 and there is also full bars but no connection. My friends, who have PCs, connect fine. There s a dell netbook and a 50lbs Toshiba laptop. I tried talking to the IT department at school but 1 of them didnt know how to operate my trackpad, my 8 yr old sister does every day, and the only other guy there said he would not operate a mac. Needless to say i was pretty pissed off. I have already tried different Ip adresses and like i sid two different OS. Any of you have any idea?
