Make sure that the Remote Wake-Up cable is plugged into the NIC and to the PC motherboard. Unplug and reconnect the cable to ensure a good connection.

2Replace the Remote Wake-Up cable with a known functioning Remote Wake-Up cable and perform the Remote Wake-Up test again.

If Remote Wake-Up works with the new NIC installed, contact your network 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 vendor.
