I was following the directions in the activation guide got to step 3 and I connected to the mifi, but when I open my browser it says there is not internet connection. Also when I went to the IP address given in the book the directions say enter you password and admin is the default. However it also asks for a user name. Can someone tell me what that would be by default? I have fooled with this thing all night because we are going out of town tomorrow and wanted to take it and use it while traveling. Can someone help?
