1) Examine lights on DSL modem.

  • The POWER/SYNC light should be a solid green. (Line Sync)
    
  • The 10BASE-T light should be a solid green. (Ethernet)
    
  • The TX/RX light should be blinking green as you send/receive data.
• If you have an "Alcatel Speedtouch" Modem:
  • The LAN light should be blinking green as you sends/recieve data. (Ethernet)
    
  • The LINE TX light should be blinking green as you send data.
    
  • The LINE RX light should be blinking green as you receive data.
    
  • The SYNC light should be a solid green. (Line Sync)
    
  • The PWR/ALARM light should be a solid green.
• If you have a "Westell Wirespeed" Modem:
  • The POWER light should be a solid green.
    
  • The READY light should be a solid green. (Line Sync)
    
  • The LINK light should be a solid green. (Ethernet)
    
  • The ACTIVITY light should be blinking yellow as your send/receive data.

  • The ADSL light should be a solid green. (Line Sync)
    
  • The TX and RX lights should be blinking as you send/receive data.

• If you have any other type of modem you will need to consult your DSL Modem documentation to determine the state of the equipment.

2) If the LEDs on your modem do not match the descriptions above:

• First turn the modem off and leave it off for 10 seconds. 
• After 10 seconds turn the modem back on and allow 1-2 minutes for the modem to complete its initilization.
• If the light that indicates "Line Sync" does not match the description above, you do not have a working link between your location and the phone company's Central Office. You should call Coastside Net at 650-712-5933 with this information and we will start the process to have it resolved.

3) If the light that "Ethernet" does not match the description above you have a problem with the connection between your computer and the DSL modem. Double-check the ethernet cable connections at both ends. If you have any devices between the DSL Modem and the computer (such as an Ethernet hub) you will have to troubleshoot that device as a possible source of the problem.

4) If the Power (Ready) light does not match the description above then there is a hardware problem with the DSL Modem. Call Coastside Net at 650-712-5933 with this information and we will start the process to have it resolved.
