The Wake on LAN (WOL) feature of my Intel 82579V Gigabit LAN adapter is working great in case my Windows 7 PC is powered off.
But because my network card is able to wake my PC I can’t use the sleep mode. All traffic directed to my IP wakes the PC.
Any ideas on how to fix this?
Unsure what your exact version of Windows is, but this site seems to indicate a similar issue is connected to “Wake on pattern match” issues in Windows 7. And the solution appears to be to disable “Wake on pattern match” under the advanced properties tab for that network adapter as shown below:
The Intel adapter panel has the “Wake on Pattern Match” option in the power management tab:
As for what “Wake on pattern match” actually is, this answer covers it nicely; it’s basically a lot of basic network activity:
The “Wake on pattern match” option instead checks for packets that matches the operating-system-specified patterns; for example, an ARP request for the computer’s address, or a TCP connection attempt.
In contrast, a “magic packet” is a unique an—as implied—magical/non-standard bit of network communication designed specifically for unique needs of wake on LAN setups:
The magic packet is a broadcast frame containing anywhere within its payload 6 bytes of all 255 (FF FF FF FF FF FF in hexadecimal), followed by sixteen repetitions of the target computer's 48-bit MAC address, for a total of 102 bytes.
