Hayes ADSL Duo Modem User Manual page 90

If the State box at the top of the page says "showtime," make sure
that:
The RJ-11 phone cord is firmly plugged into the wall jack and
the ADSL port on the back of the modem.
The RJ-11 phone cord is connected to a DSL-enabled phone
jack. You cannot use a standard telephone jack for DSL service
unless your service provider has activated it for DSL.
Your RJ-11 phone cord is not defective. Replace the phone
cord with a known good one.
Your Ethernet or USB connections are okay. Check that the
correct ADSL Duo front panel light is lit (LAN or USB). This
will confirm that the connection is good.
You have installed phone filters on all the phones and fax
machines using the same DSL line as the modem. These
devices can produce noise and interfere with your DSL
connection.
You did not inadvertently change your modem's DSL
configuration values. If you think this may be the case, using a
paper clip, press the RESET button on the modem's back
panel. While holding in this button, count to five, and then
release the button. The front panel LINK light will turn off
and then blink slowly, about once per second. You are now
guaranteed that all system settings are restored to the unit's
factory defaults. (Note: If you had changed your Protocol,
VPI, VCI, or encapsulation settings since purchasing the
modem, you need to re-enter this information; refer to page 11
if you need help).
If the State box at the top of the ADSL Status page says
"showtime," but the State field under Connection Status at the
bottom of the page does not say "Connected," make sure that:
Your computer's TCP/IP properties are correct.
Windows users:
Go to Start | Settings | Network and Dial-up
Connections.
