System can't go to sleep likely because of wake on LAN

[robilong]

Mobo Intel DP55WB. Computer cant enter into standby. In event Viewer I found System:
e1kexpress - Intel 8257DC Gigabit Network Connection - Network is disconnected
and 3 seconds later
Intel 8257DC Gigabit Network Connection - Network link has been established at 1Gbps full duplex
following in 2 seconds
The PCP/IP NetBIOS Helper service enetered the running state
following in 2 seconds
Power troubleshooter -> The system has resumed from sleep ... sleep time approximately 10 seconds
The mobo's BIOS doesn't have Wake on Lan on/off option.

How to troubleshoot, any ideas?
Does Windows has any overriding power settings?
Thanks!
