Here is my problem! I don´t Know if I´m the only one but about two weeks ago I update my computer from vista to windows 7 ultimate, the problem is that at home I don´t have any problem to get conexion to my private wireless network but at work there is a public wireless network and I can see the network I click to conect but after a few minutes shows me a message saying "network not identified, no internet access" . apparently all the adpators and drivers are working properly. I don´t which way to take or where to walk with this problem... if somebody knows something about it please help me!!!!
