The Scientific-Atlanta WebSTAR DPX-110-series cable modem has four LED lights on the front indicating the network status. These indicate the following:
If the power light is blinking, your modem is not associated with your internet service. You will need to call our technical support department at 1-866-WAVE-123 (1-866-928-3123) to make sure your account is active and your modem is registered with our system.
If the PC light is blinking or solid, your modem is connected to your computer, or your router if you are using one. The next step is to check to see if your computer or home network is online.
If the cable light is blinking, your modem is showing current internet activity from your computer or home network.
If the status light is blinking, your modem is securing a connection to the network that can be used to access the internet. Once the status light turns solid, the modem is connected. If it continues to blink without turning solid, there is no connection to the internet. Check the cable line that screws into the back of the modem and make sure it is secure. If necessary, bypass any splitter and run the cable directly from the outlet to the modem.
If your modem is unable to get online, you will want to reset it. Remove the power cord from the back of the modem, and let it sit without power for at least 30 seconds. Then restore power to the modem and determine if it can get online. If the modem cannot connect to the internet, please call our technical support department at 1-866-WAVE-123 (1-866-928-3123) so we can determine if a service call is required.
If you have a router, you will want to disconnect power to the router while the modem is unplugged, and leave the router without power while the modem is getting connected to the internet. Once the status light is solid, you can restore power to the router, and the PC light on the modem should turn on, either blinking or solid.
