I can’t access the internet. z Check all of the connections to your EMTA Gateway. z Your Ethernet card or USB port may not be working. Check each product’s documentation for more information. z The Network Properties of your operating system may not be installed correctly or the settings may be incorrect. Check with your ISP or cable company. All of the lights are flashing in sequence. z This means the EMTA Gateway is automatically updating its system software. Please wait for the lights to stop flashing. The updating process typically lasts less than one minute. z Do not remove the power supply or reset the EMTA Gateway during this process. I can’t get the modem to establish an Ethernet connection. z Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer has a properly installed Ethernet card and the driver software to support it. z Check to see that you are using the right type of Ethernet cable. The modem won’t register a cable connection (CABLE LINK light not on continuously). z If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable Company if it has not completed this 5-step process within 30 minutes, and note which step it is getting stuck on. (See page 24 for details.) z The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than one your Cable Company recommends, or if the terminal connections are loose, it may not work. Check with your Cable Company to determine whether you’re using the correct cable.  z If you subscribe to video service over cable, the cable signal may not be reaching the modem. Confirm that good quality cable television pictures are available to the coaxial connector you are using by connecting a television to it. If your cable outlet is “dead”,
Chapter 3: Additional Information  42 call your Cable company. z Verify that the Cable Modem service is DOCSIS-compliant and PacketCable-compliant by calling your cable provider. I don’t hear a dial tone when I use a telephone. z Telephone service is not activated. If the rightmost light on the EMTA Gateway stays on while others flash, check with your TSP or cable company. z If the EMTA Gateway is connected to existing house telephone wiring, make sure that another telephone service is not connected. The other service can normally be disconnected at the Network Interface Device located on the outside of the house.   z If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
