They claim many great things, such as, you will never have to upgrade them, instead just download the latest updates. These software modems use a modem card that has less chips on it and therefore costs less to make and sell. The cost benefits are far outweighed by the reliability and speed issues with these modems. One fact about software modems is that, if your system is not working perfectly or you are running heavy applications, such as graphical games, your connections are going to be much less reliable.
