My modem doesn't dial out or doesn't answer incoming
calls.
Solution 1:
You may have a bad telephone cord. Try another telephone cord.
Solution 2:
You may have plugged the modem's phone cord into a digital line. Contact the department responsible for
your phone system if you are unsure whether your phone line is analogue or digital.
Solution 3:
If your phone system requires an access code to access an outside line, be sure to include the code in the
number that you are dialling.
Solution 4:
If your voice mail alters your dial tone when messages are waiting, restore the normal dial tone by
retrieving your messages before using the modem to dial out.
My modem tries to connect to another modem, but the
connection fails.
Solution:
You may have a poor connection. Try placing the call again.

My modem or computer is performing erratically.

Solution:
Some USB host controllers have power output issues which may cause erratic performance for any USB
device or the computer itself when any USB device is in use. Try using a powered USB hub or check with
the manufacturer of your USB host controller for a possible driver update.
