Help! I have a Dell Inspiron 3800 laptop from work. No one will help me with this issue. At work, I use a network connection. No biggie. However, I am trying to set up a Dial-Up connection at home and I am receiving a line failure. The diagnostic says that the modem is working properly (by the way, LT Win Modem) but it cannot detect the line. I have check the phone cables, tried several, and check the the outlets (plugged in a phone and received a dial tone.) Can anyone help me?
