Troubleshooting
Remote Wake-Up
If your PC supports Remote Wake-Up and fails to boot when a wake-up packet is
sent over the network, perform these troubleshooting steps:
1 Make sure that the PC meets Remote Wake-Up requirements.
For information on Remote Wake-Up requirements
Go to: Remote Wake-Up .
2 Make sure that you are using the latest driver for the NIC.
A driver is on the EtherCD that ships with the NIC. Download the latest driver from
the 3Com World Wide Web site:
Go to: http://www.3com.com/ .
NOTE: If a red circle with a line through it appears over the 3Com icon, there is no
connection between the NIC and the network.
