Common Technical Questions
- Verify that the cable modem and computer are disconnected from the power source.

Most cable modems are "on" all the time and do not have a switch. If the modem has a power switch, turn on the modem and wait for the modem to synch with the cable network. This may take up to five minutes.
- Connect one end of the Ethernet cable to the back of the modem.
- Connect the other end of the Ethernet cable to the back of the computer.
- Connect the power to the computer and turn the computer on.
- Check the modem lights for proper status. Most modem lights operate similarly. Some blink at start-up, then become steady, except for the “activity” light, which may blink continuously. If modem lights do not come on, turn off the computer, unplug the modem, wait 30 seconds, plug the modem back in, then restart the computer.
Result: The modem is now connected and ready.
