I am writing on behalf of my friend. Her white Macbook is having some problems connecting to the internet at a specific location. My macbook and other laptops connect to the internet without any problem, but she has been having problems. Airport connects to the network and even assigns an IP address properly, but the safari or firefox doesn't open any websites. I tried manually assigning IP address but didn't work either. I am not very good at solving problems with Macs so any help is welcome. edit: sometimes it is a bit difficult to assign the IP address, but it does end up assigning one.
