I have a MacBook Pro and am pretty new to this world and loving it...having just come across from the darkside....I have semalessly connected into every wireless envrionment I have had to work in until today in a hosted serviced office environment...the machine detects the wireless network; it connects and attmepts to link to the "https://securelogin.xxx.xxx" location where username and password has to be entered but it freezes on that site before loading and locks safari and the mail client..it recognises the wireless network but wont connect any further...all the lights on the diagnostic are green but everything is still locked and no internet...when I move to another location and a dififerent wireless network it all connects and the browsers and email all work...but when I then go to check the http://securelogin.xxx site it locks the browser and mail client again...has anyone got an idea of what may be happening and how I fix it?..
