Normally, you can go to either the Control Panel->Internet Options and select the "Connections" tab. I think the modem you are using should be in the "Dial-Up" window. I think this should work for both IE and Firefox, but I can't be sure.
Could I ask you to give a detailed explanation of how you connect to the Internet with the Smartview? What type of device you use? What do you have to do with the laptop to connect to the Internet? Do you have to plug in something and then activate some software? As I mentioned before, I don't use Smartview, so any information may be helpful to understand what is happening.
