Router Troubleshooting Guide

Use these FAQs to troubleshoot your WarpTworouter.

  1. The ISDN LED is not ON.
  2. The B1 (or B2) LEDS are not ON.
  3. The NET 1 (or NET 2) LED comes on for a few seconds then goes OFF again.
  4. The NET LED is ON the other comes ON for a few seconds then goes OFF again.
  5. Both NET LEDS are ON.
  6. Only one NET LED is ON.
  7. The POWER LED is not ON.
  8. The LINK LED is not ON.
  9. The router is functioning normally but I cannot configure it or use Telnet.
  10. I have just updated the Route Table (or any table) and want to use the new parameters immediately.

All the configuration answers assume you have downloaded and installed CoolFig the standard router configuration utility. You can download CoolFig here


The ISDN LED is not ON.

This indicates that your ISDN line is not connected or is not functioning (synchronizing) correctly.

  1. Check that the ISDN line is connected to the rear of your router (see controls and indicators).
  2. Check that the ISDN line is connected to your wall jack or termination.
  3. Check that you are connected to an ISDN U interface and that you do NOT have an NT1 device connected (your router has a built-in NT1 for use in North America).
  4. If you have another ISDN U interface device does it synchronize on this line?

If items 1, 2 and 3 are OK then it is most likely your ISDN Line. Contact your Telephone Service Provider and have then run a check. If item 4 is true and the replacement device definitely connects to a U interface then your router maybe faulty. Contact support.

The B1 (or B2) LEDS are not ON.

If the ISDN LED is NOT ON follow this procedure first.

If your ISDN LED is ON and the B1 (and/or the B2) LED is OFF then you may have an incorrect SPID or the there may be fault with your ISDN line.

  1. If you have just changed the SPID, reset your router to ensure the changes take effect (or use CoolFig’s Update Menu ,SPID Table followed by DN Table).
  2. Check that your SPIDs are correct (use CoolFig’s Router Summary window, ISDN Line Configuration). If one or both SPIDs are incorrect edit then in the Router Summary window and click Update.
  3. If the unit was operational prior to this and you did NOT change the SPID, report the fault to your Telephone Service Provider.
  4. Try removing the ISDN line from the connector (see controls and indicators) for about 30 seconds then replace it.

NET 1 (or NET 2) LEDs comes on for a few seconds then goes OFF again.

This means you are dialing a remote network number and not connecting.

  1. Verify using CoolFig’s Router Summary window that the ‘Link speed and Type’ parameters are correct ‘Remote Telephone Numbers’ are correct.
  2. Verify using CoolFig’s Router Summary window that the ‘Remote Telephone Numbers’ are correct.
  3. Verify using CoolFig’s Router Summary window that the ‘Link Security’ parameters are correct.
  4. Verify that the phone number being used is serviceable by dialing it using a normal telephone.

One NET LED is ON the other comes ON for a few seconds then goes OFF again.

This means that your second connection is not configured properly or you are dialing a remote network and not connecting.

  1. Verify using CoolFig’s Router Summary window that the ‘Link speed and Type’ parameters are correct ‘Remote Telephone Numbers’ are correct.
  2. Verify using CoolFig’s Router Summary window that the ‘Remote Telephone Numbers’ are correct.
  3. Verify using CoolFig’s Router Summary window that the ‘Link Security’ parameters are correct.
  4. Verify that the phone number being used is serviceable by dialing it using a normal telephone.

Both NET LEDS are ON.

This is normal is you are using a 128K service. You can verify the configuration as follows:

  1. Load CoolFig
  2. Go to the Router Summary window.
  3. Find the correct route.
  4. Expand ‘Remote Connection Details’.
  5. Expand ‘Link Speed and Type’.
  6. If the configuration is incorrect click any value, then click again (not double click) and you will be presented with a display that will let you change the configuration.
  7. Run Update from the Router summary window.

Only one NET LED is ON.

This is normal is you are using a 64K service. You can verify the configuration as follows:

  1. Load CoolFig
  2. Go to the Router Summary window.
  3. Find the correct route.
  4. Expand ‘Remote Connection Details’.
  5. Expand ‘Link Speed and Type’.
  6. If the configuration is incorrect click any value, then click again (not double click) and you will be presented with a display that will let you change the configuration.
  7. Run Update from the Router summary window.

If the Speed is correct and you are using a dynamic service this indicates that you are not using enough bandwidth to trigger the threshold for use of the additional channel. You may want to review or experiment with your connection parameters with this in mind.

The POWER LED is not ON.

This means no power is reaching your ISDN router.

  1. Check that the power connector is snugly connected to the rear of the router (see controls and indicators)
  2. Check that the power cord or transformer is properly connected to a power socket.
  3. If WarpTwo.6 model ONLY check that the ON/OFF switch on the front of the unit is in the ON position (see controls and indicators).
  4. Place another device of any kind into the power socket and confirm it is operational (if NOT your power circuit has fused).

Go to Top


The LINK LED is not ON.

This means that you are not connected to any local LAN.

WarpTwo.1

  1. Check that you have a LAN (category 3 or 5) cable connected to the rear of the unit (see controls and indicators) and to either a PC or a HUB. NOTE: Over time connections can become loose or corroded, remove and re-insert both connectors.
  2. If you are connecting DIRECTLY from a PC to the router (without a HUB) this cable MUST be a PC-to-PC (crossed) cable type. NOTE: The normal cable type is PC to HUB (uncrossed or straight).
  3. If you are connecting from a HUB to the router use a normal PC-to-HUB (uncrossed) cable.
  4. Try another cable of the same type.
  5. Check that your HUB is powered ON.
  6. Move the cable to another port on your HUB.

WarpTwo.6

  1. Check that you have a LAN (category 3 or 5) cable connected to the rear of the unit (see controls and indicators) and to either a PC or a HUB. Check carefully the setting of the UPLINK switch. NOTE: Over time connections can become loose or corroded, remove and re-insert connectors.
  2. Try another cable of the same type.
  3. Move the cable to another port on the WarpTwo.6 HUB.

The router is functioning normally but I cannot configure it or use Telnet

The most likely explanation is that you have a router lockout condition. Follow this procedure to diagnose and recover.

I have just updated the Route Table (or any table) and want to use the new parameters immediately.

If you use CoolFig's Update button on the Router Summary window then it will present you with an option to update the router immediately to use the new parameters. If you did not use this method of update or declined the automatic update you will have to manually update the Table that you changed from CoolFig’s Update Menu.
