After my modem dials out, I hear a message stating that the number is not in service or has been disconnected.

As soon as my modem connects, I get an error message that I have been disconnected.

Why can't I get the maximum speed of my modem?  I have a 33,600bps modem, but I only get 28.8Kbps at best.

I'm using a US Robotics Sportster modem and can connect to 95Net just fine.  Shortly after however, the connection gets slower and eventually dies.

How can I get the full 56K speed?

I signed up for a 56K account, but I can't get beyond a 33.6K connection.

Is there any way to automate the dial-up connection, so I don't have to click Connect every time?
