I'm trying to access an unsecure network with my MacBook pro osx version 10.4.11. I have permission to access it (it's from a hotel). There are some other people with a pc and with a mac who can Access it. It says i am connected on my airport but when I open safari or firefox it gives me an error message. I can also access it on my iPhone...I hAve little knowledge of techinology so a step by step explanation would be appreciated.
