1. Ensure that the telephone cord is securely connected at both modem and wall outlet.

2. Unplug the telephone cord from the computer and connect it directly to a telephone from the wall outlet. Check for a dial tone. If there is none, the problem is in the telephone cord or system. Call your telephone service provider.

3. Double-check your country setting. Different country setting will cause different modem performance. Please select the correct country as you located.

4. Check modem performance with a direct line from your telephone company. Some PBXs may cause the telephone line condition change and affect modem performance.
