Troubleshooting Remote Wake-Up

If your PC does not boot in response to a Remote Wake-Up event, perform these troubleshooting steps:

  1. Make sure that the PC meets the Remote Wake-Up requirements listed in Chapter 1.
  2. Make sure that you are using the latest driver for the NIC.
  3. This driver is shipped with the NIC on the EtherCD. It can also be downloaded from:
    http://www.3com.com/
  4. Perform the Remote Wake-Up Test.
  5. See Running the NIC Diagnostics Tests for instructions.
  6. Check the PC BIOS.
    1. Boot the PC and enter the BIOS.
    2. If you do not know how to enter the BIOS, consult the reference manual for your PC or contact your PC vendor.
    3. Locate the Wake-Up on LAN event setting.
    4. Verify that the setting is enabled.
  7. Check the Remote Wake-Up cable connection.
  8.  

     

    If you have a 3C905C-TX-M NIC and your PC is compliant with PCI 2.2, the Remote Wake-Up cable is not required. Remote Wake-Up is automatically enabled through the PCI bus.
    1. Turn off the power to the PC and remove the PC cover.
    2. Make sure that the Remote Wake-Up cable is plugged in to the RWU connector on the NIC and in to the appropriate connector on the PC motherboard. Unplug and reinsert the cable if necessary.
    3. Replace the Remote Wake-Up cable with a known functioning Remote Wake-Up cable and perform the Remote Wake-Up Test again.
  9. If the previous steps have failed, install a known functioning Remote Wake-Up NIC in the PC.
  10. If Remote Wake-Up works with the new NIC installed, contact your PC vendor for a replacement NIC.
    If Remote Wake-Up does not work with the new NIC installed, there may be a problem with the PC motherboard. Contact your PC manufacturer.
