Sony VAOI laptop modem has no dial tone
I have been using juno dial up for years. The laptop gets no dialtone message. The desktop was doing the same thing. I switched from fiberoptic to ATT and the desktops dials up juno. The laptop does not. The laptop works WiFi. I bought a USB external dial up modem and still no dial tone. I have run down the list of everything that juno suggests in trouble shooting. Does anyone have a suggestion how to fix this problem?
