This is my second replacement 9000 this week. I've had this model for 8 months now and have always used wi-fi whereever I can pick up an open connection. Of course my home connection is secure; however all of a sudden since receiving this one (two days ago), I'm getting the message, 'you are trying to open a secure connection, but the server's certificate is not trusted.' What gives? When I click connect, wi-fi starts right up, but I have to go through that prompt first. Thanks for any help.
