Intel® Ethernet Adapter Power Management related Known Problems and Solutions

by Cengiz Kuskaya

Some of the most known Intel® Ethernet Adapter Power Management related Problems and Solutions

1. System does not wake when expected.
Under Microsoft Windows Server 2012, the system may not wake even though Wake on LAN settings are enabled.
Disabling Fast Startup in the operating system should resolve the issue.

2. Intel® Ethernet Controller X710 series devices do not support Wake-On-LAN in multicast mode.
Devices based on the Intel® Ethernet Controller X710 do not support Wake-On-Lan (WOL) in multicast mode.

3. System does not wake on link.
On a driver-only installation, if you change ‘Wake on Link Settings’ to Forced and change ‘Wake on Magic Packet’ and
‘Wake on Pattern Match’ to Disabled, the system may not wake up when expected. In order to “Wake on Link”
successfully, check the Power Management tab and make sure that “Allow this device to wake the computer” is
checked. You may also need to change ‘Wake on Magic Packet’ or ‘Wake on Pattern Match’ to Enabled.

4. Directed Packets may not wake the system.
On some systems, quad port server adapters may not wake when configured to wake on directed packet. If you
experience problems waking on directed packets, you must configure the adapter to use Magic Packets*.

5. Power Management options are unavailable or missing.
If you install only the base drivers, later install Intel® PROSet for Windows Device Manager, then remove Intel
PROSet, the settings on the Power Management tab on the Adapter Property Sheet may be unavailable or missing
altogether. You must reinstall Intel PROSet to resolve the issue.

6. System Wakes-Up from a Removed VLAN.
If a system goes into standby mode, and a directed packet is sent to the IP address of the removed VLAN, the system
will wake-up. This occurs because a directed packet bypasses VLAN filtering.

7. Intel Adapters ignore consecutive Wake Up signals while transitioning into standby mode.
While sending a system into standby, occasionally a wake up packet arrives before the system completes the
transition into standby mode. When this happens, the system ignores consecutive wake up signals and remains in
standby mode until manually powered up using the mouse, keyboard, or power button.
