unable to connect to the internet for installation

hello everybody, I am trying to install Debian (Potato), via floppy and the internet. My problem is that the connection process normally involves a terminal window popping up after my ISP has been dialled up. Then I manually type in the username and then the password... And THEN it says:

installing via apt/ppd
