I've been able to use my Mobile broadband for months till last week. It keeps popping out "Error 633 : modem or connecting device in use or not configured properly". It works fine with my brother's laptop though. I spent a week poring through the net looking for various solutions and nothing seems to work. Can anyone help me?

Hi, Thanks for the post! Do you have another active broadband connection? If so, disconnect with that one. Restart the computer and enter into the Safe Mode with networking, does it work here? Also reinstall the latest modem driver.
