If you are having problems receiving e-mail or browsing the Web, you should verify that your cable modem is successfully communicating with the Mediacom Online network.
Your cable modem owner's manual should describe the functions to which the lights on the front of your modem correspond. Look at the front of your cable modem to ensure that the cable connection indicator light is blinking. Depending upon the type of modem you are using, this light may be labeled as status, online or cable.
If the corresponding light is blinking, you may need to reset the modem. To do so, press the reset button on the front or back of your modem. If your modem does not have a reset button, you will need to powercycle your modem.
If, after one to two minutes, the light on your cable modem continues to blink, a service call may be required.
