This was probably due to EEE's weak compatibility with other networking hardware. This program is language independent and can be used with any language system. The second feature implementing the Energy-Efficient Ethernet standard would cause WoL to be unreliable if a workstation was powered on for a long time, but idle. Intel 82577LM Gigabit Network Connection If this package has been installed, updating (overwrite-installing) this package will fix problems, add new functions, or expand functions. Enabling PME for a NIC (by doing that in the Advanced tab of the NIC's device settings in Device Manager) would allow WoL to function.

With the Intel NIC drivers Windows 7 disables PMEs ( Power Management Event) on a shutdown which renders WoL unusable.

The issue was being caused by driver features for power saving: PME and EEE
We've had similar issues with WoL on newer Intel cards on Windows 7. They are well formatted regardless of the whether the ping request goes first or not.Īm I overlooking something obvious here? It seems like an unlikely flaw in an ethernet controller that an icmp request qould "block" for subsequent magic packets.Īny thoughts on this (additional tests to perform etc.) would be much appreciated before I go talk to Intel. I've also looked at the magic packets using tcpdump. I've tried using two different devices to run the wake script using different wake-on-lan-utilities (wake on lan and etherwake) and the results are the same. This dt' value causing the computer to wake is 20-40 seconds. Regardless of the value of dt (dt = 0, 0.5s, 2s) if the script is invoked twice in a row, with a time inteval dt' between invocations, the computer will wake.

The script would then be invoked like "wake.sh ip mac dt". Wakeonlan -p 7 $2 # Could be wakeonlan or etherwake or similar This script is a minimal implementation of the scenario I am talking about: #!/bin/sh The computer wakes as it is suppose to due to the magic packet So basically if I send an icmp echo request and wait a time dt before sending a magic packet I will experience the following: I am experiencing a very annoying and mysterious behavior when sending magic packets (for Wake On LAN) shortly after pinging an Intel 82579LM GigaBit Ethernet Controller (the onboard ethernet controller of the Intel DQ67SW motherboard).
