Troubleshooting with the LED lights on the Lingo Phone Adapter

Lingo Phone Adapter (figure 1)

Here is another way to make sure these instructions apply to your adapter:

1. Turn your device upside down.
2. Find the small rectangular sticker that looks like this:
   
   
   
3. The first six (6) characters should be either 00028A or 000E9B.

When you have a problem with Lingo's VoIP service a good place to start is the front of the adapter. Your Lingo Phone Adapter has six (6) lights on the front. They are often called “LED” lights for the type of bulb inside (Light-Emitting-Diode).

1. Purpose for Lingo Phone Adapter LED lights:
   
   1. PWR – Lets you know if the phone adapter is plugged in and getting power.
      
      
   2. WAN – Tells you if the phone adapter is connected to your modem or router.
      
      
   3. ENET – Shows you the physical activity for any computer or router plugged into the “ENET” port on the back of the phone adapter. Use of the ENET port is not required for Lingo's VoIP service to work.
      
      
   4. VOIP – Lets you know if you have successful registration on our VoIP network. “VoIP” is short for “Voice over Internet Protocol” - the technology that Lingo uses to place and receive calls over the Internet. Successful registration is required for VoIP use.
      
      
   5. PHONE 1 & PHONE 2 - These lights tell you the status of the phone or fax machine plugged into the phone jack of the same name. Note that these lights are not related to receiving dial-tone or ability to place and receive VoIP calls (that is the function of the “VOIP” light).
      
      
2. Normal status of Lingo Phone Adapter LED lights:
   1. PWR – The LED should be a steady green light, indicating the phone adapter has power.
      
      
   2. WAN – The LED should be a steady green light or a blinking green light. When the WAN light is steady, it means that a cable is connected to the WAN port on the back of the adapter but the connection is not actively in use. When the WAN light blinks, it means the adapter is accessing your modem or router. The speed of the blinking changes depending on how much and how fast this is happening. When not using your phone or computer, the WAN light may be steady or it may blink; this is normal.
      
      
   3. ENET – The LED should be a steady green light, a blinking green light, or off. When you have a computer or router plugged into the ENET port, this light works like the WAN light (above). It will be a steady green when connected and a blinking green when working to communicate with the computer or router attached to it. This light will remain off when nothing is plugged into the ENET port, the attached device is disabled, or an incorrect/bad cable is attached. Use of the ENET port is not required for Lingo's VoIP service to work.
      
      
   4. VOIP – The LED should be a steady green light, indicating the phone adapter is ready for you to place or receive calls.
      
      
   5. PHONE 1 – The LED should be a steady green light when you pick up the attached phone. The green light will flash rapidly when you receive a phone call.
      
      
   6. PHONE 2 - Only customers with a Lingo “Office” or “Business” VoIP plan will be able to use the PHONE2 jack. The LED should be a steady green light when you start a fax transmission or pick up the handset on an attached fax machine. The green light will flash rapidly when you receive a fax call.
      
3. Recommended actions for troubleshooting Lingo's VoIP phone service using the adapter’s LED lights:
   
   Compare the current status of the lights to the above list (“B. Normal status of Lingo Phone Adapter LED lights”).
   
   1. If all of the lights are operating as described and you are still experiencing a problem with your VoIP phone service, you should contact Lingo technical support by phone at 888-Lingo-99(546-4699).
   2. If any of the lights are not operating as described above, use the following recommendations to troubleshoot the problem light(s).
      1. Try each recommended action one at a time. If it fixes the problem, stop there. If it does not fix the problem, move on to the next recommended action.
      2. If more than one light is not operating as described, troubleshoot them in the order presented below (left to right across the face of the phone adapter).

PWR – Should be a steady green. If it is not try these actions:

1. Check if any other lights on the phone adapter are lit. If so, then your PWR LED is defective, but your Lingo Phone Adapter should still operate correctly.
2. Verify that the thin cord from the rectangular power converter (figure 3, below) is plugged completely into the Lingo Phone Adapter.
3. Verify that the thick cord from the power outlet is plugged completely into the rectangular power converter (figure 3, below).
4. Verify that the thick cord (figure 3, below) is plugged into a live outlet (check wall switches, surge-suppressors, light timers, etc.).
5. If the PWR light and all other lights are still off please contact Lingo technical support by phone at 888-Lingo-99(546-4699).

AC adapter (figure 3):

WAN – Should be a steady or a blinking green. If not, try these actions:

1. Verify that you have followed the correct installation instructions for VoIP service as found on Lingo Support.
2. Power-cycle both devices. To do so, follow each of these steps in order:
   1. If you have a DSL modem, skip ahead to step 2. If you have a cable modem, do the following:
      1. Turn off the power to the modem and unplug the Lingo Phone Adapter. If you have a router placed between the modem and the Lingo Phone Adapter turn it off, too.
      2. If you have a router placed between the modem and the Lingo Phone Adapter, restore power to it and wait until it is successfully connected to the modem (see your router’s documentation for how to tell).
      3. Restore power to the Lingo Phone Adapter.
      4. Restore power to the modem and wait for it to establish an Internet connection (see your modem’s or ISP’s documentation for how to tell when you are connected to the Internet).
      5. If this does not restore your Internet connection, move on to step 2.
   2. For DSL modems or for cable modems that did not respond to the procedures in step 1, do the following:
      1. Turn off the power to the modem and unplug the Lingo Phone Adapter. If you have a router placed between the modem and the Lingo Phone Adapter turn it off, too.
      2. Restore power to the modem and wait for it to establish an Internet connection (see your modem’s or ISP’s documentation for how to tell when you are connected to the Internet).
      3. If you have a router placed between the modem and the Lingo Phone Adapter, restore power to it and wait until it is successfully connected to the modem (see your router’s documentation for how to tell).
      4. Restore power to the Lingo Phone Adapter.
3. Verify that the modem or router your Lingo Phone Adapter is plugged into is turned on and has access to the Internet. The best way to verify this is to plug a computer directly into the modem. Power-cycle the modem and reboot the computer. Open up your web browser and see if you can access the Internet. If you can not, then contact your ISP. If you can, then continue trying these recommended actions.
4. Verify that the Ethernet cable from your modem or router is plugged into the WAN port on the back of the phone adapter.
5. Verify that you are using an Ethernet cable and not a telephone cable (figure 4, below).
6. Verify the plugs on the Ethernet cable are securely plugged into the ports. You should hear a “click” when they plug in.
7. Try replacing the Ethernet cable between the phone adapter and your cable modem with a new Ethernet cable. One is provided with the Lingo Phone Adapter.
8. If you have a router placed between the modem and the Lingo Phone Adapter, replace the modem with the Lingo Phone Adapter. See our recommended method for installing Lingo with a router for help with this setup.
9. If you are a DSL customer that uses PPPoE (a user name and password) to log onto your ISP, make sure you have followed the install instructions here: Configuring PPPoE (Advanced).
10. If your ISP provides you with a Static IP address (usually a feature you would be paying extra for), make sure you have followed the install instructions here: Configuring Static IP (Advanced).
11. Some modems require the use of a “cross over” cable when connecting the modem to something other than a computer. Check your modem’s documentation or with your ISP to see if your modem requires one. If it does, use a cross over cable to connect your modem to the Lingo Phone Adapter’s WAN port. There are two ways you can tell whether your cables are straight-through or crossover:
    1. Check the small printing on the side of the cable. A cross over cable should (but not always) be stamped with “CROSS OVER”, “X-OVER” or similar.
    2. Hold the ends of the cable side by side, with both spring clips facing down. The plugs are see-through (figure 4, below). Look through them and compare the order of the colored wires.
       1. If the plugs have the same order of wire colors in each tip then it is a straight-through cable.
       2. If the plugs have a different order of wire colors then it is a crossover cable.
12. If you still can not get the WAN light on or blinking, please contact Lingo technical support by phone at 888-Lingo-99(546-4699).

ENET – If you have a computer or router set up to obtain Internet access through the Lingo Phone Adapter’s ENET port then this light should be a steady or a blinking green. If you have a device plugged in but the ENET light is off, try these steps:

1. Verify that the computer or router plugged into the ENET port is turned on and has power.
2. Power-cycle all devices. To do so, follow each of these steps in this order:
   1. Turn off the power to the modem and the router. Unplug the Lingo Phone Adapter.
   2. Restore power to the modem and wait for it to establish an Internet connection (see your modem’s or ISP’s documentation for how to tell when you are connected to the Internet).
   3. Restore power to the Lingo Phone Adapter. Wait until you see the WAN light blinking.
   4. Restore power to the computer or router that is connected to the ENET port on the Lingo Phone Adapter.
3. Verify that the Ethernet cable from your router’s “WAN” or “INTERNET” is plugged into the “ENET” port on the back of the Lingo Phone Adapter.
4. Verify that you are using an Ethernet cable and not a telephone cable (figure 4, above).
5. Verify the plugs on the Ethernet cable are securely plugged into the ports. You should hear a “click” when they plug in.
6. Try replacing the Ethernet cable between the Lingo Phone Adapter and your device with a new cable. One is provided with the Lingo Phone Adapter.
7. Verify that the cable plugged into the ENET port is a standard straight-through Ethernet cable and not a “cross-over” Ethernet cable. There are two ways you can tell whether your cables are straight-through or cross over:
   1. Check the small printing on the side of the cable. A cross over cable should (but not always) be stamped with “CROSS OVER”, “X-OVER” or similar.
   2. Hold the ends of the cable side by side, with both spring clips facing down. The plugs are see-through (figure 4, below). Look through them and compare the order of the colored wires.
      1. If the plugs have the same order of wire colors in each tip then it is a straight-through cable.
      2. If the plugs have a different order of wire colors then it is a crossover cable.
8. If you have a router plugged into the Lingo Phone Adapter’s ENET port, remove it and plug your computer directly into the ENET port. Power-cycle the modem and the Lingo Phone Adapter, then reboot the computer. Open up your web browser and see if you can access the Internet. If you can, then the problem is with your router. Troubleshoot the router using the documentation the manufacturer provided you, or contact the manufacturer.
9. If you still can not get the ENET light on or blinking, please contact technical support by phone at 888-Lingo-99(546-4699).

VOIP – Should be a steady green. If not, try these steps:

1. Make sure the WAN light is on or blinking (see “WAN” above). The VOIP light needs Internet access in order to work.
2. Power-cycle the modem and the Lingo Phone Adapter. To do so, follow each of these steps in this order:
   1. Turn off the power to the modem and unplug the Lingo Phone Adapter. If you have a router placed between the modem and the Lingo Phone Adapter turn it off, too.
   2. Restore power to the modem and wait for it to establish an Internet connection (see your modem’s or ISP’s documentation for how to tell when you are connected to the Internet).
   3. If you have a router placed between the modem and the Lingo Phone Adapter, restore power to it and wait until it is successfully connected to the modem (see your router’s documentation for how to tell).
   4. Restore power to the Lingo Phone Adapter.
3. If you have a router placed between the modem and the Lingo Phone Adapter, remove it and plug the Lingo Phone Adapter’s WAN port directly into the modem. See our recommended method for installing Lingo with a router for help with this setup.
4. If you still can not get the VoIP light on, please contact technical support by phone at 888-Lingo-99(546-4699).

PHONE 1 – For all plans, this light should be a blinking green when you receive a call, a steady green when you “pick up” the phone that is plugged into the PHONE1 port, and off when the phone is not in use. If not, try these steps:

1. Pick up you telephone’s receiver (press “talk” or similar on a cordless phone). If the PHONE 2 light comes on, then your telephone is plugged into the wrong jack on the back of the Lingo Phone Adapter. Switch it to the PHONE1 jack.
2. Verify the plug on the telephone cable is securely plugged into the port. You should hear a “click” when it plugs in.
3. Try using a different phone cord. Two are provided with the Lingo Phone Adapter.
4. Try using a different analog phone. If this works, the problem is with the first telephone.
5. If you still can not get the PHONE 1 light on, please contact technical support at 888-Lingo-99(546-4699).

PHONE 2 – For Lingo Office VoIP service only: This light should be a blinking green when you receive a fax on the fax machine that is plugged into the PHONE2 port. It will be a steady green when you send a fax or pick up the fax machine handset. It will be off when not in use. If not, try these steps:

1. The PHONE2 jack is only active for customers who subscribe to a Lingo Office VoIP service plan. If you are not an Office plan subscriber, then you do not need to troubleshoot this light.
2. Pick up the fax machine handset or initiate a fax send. If the PHONE 1 light comes on, then your phone is plugged into the wrong jack on the back of the Lingo Phone Adapter. Switch it to the PHONE2 jack.
3. Verify the plug on the telephone cable is securely plugged into the port. You should hear a “click” when it plugs in.
4. Try using a different phone cord. Two are provided with the Lingo Phone Adapter.
5. Try plugging in an analog phone and placing a test phone call with it. If this works, the problem is with the fax machine.
6. If you still can not get the PHONE 2 light on, please contact technical support by phone at 888-Lingo-99(546-4699).
