Remote Wake-Up Cable This procedure applies to 2.1 PCI specification-compliant PCs that support Remote
Wake-Up using a cable connected to the 3-pin connector on the NIC and the PC
motherboard.
1 Turn off the PC power, remove the PC cover, and check the Remote Wake-Up
cable connection.
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.
2 Replace the Remote Wake-Up cable with a known functioning Remote Wake-Up
cable and perform the Remote Wake-Up test again.
3 If the previous steps have failed, install a known functioning Remote Wake-Up NIC
in the PC and connect the Remote Wake-Up cable.
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.

Troubleshooting a
Network Connection
When working with 10BASE-T or 100BASE-TX cabling, concentrators, and NICs
from different vendors, it is possible to connect everything but still have no
network communication.
To narrow the range of possible causes of common network connection problems:
1 Determine whether your equipment complies with the 10BASE-T or
100BASE-TX standard.
This is particularly important for data concentrators (hubs or repeaters).
