We have a number of Dell Optiplex 320s, which are rejecting wake on LAN requests following upgrade from Windows XP to Windows 7.
The onboard network adapter is a Broadcom 440x 10/100 Integrated Controller. The latest driver v220.127.116.11 is installed. I've also tried a different network adapter, Realtek RTL8139/810x Family Fast Ethernet NIC.
WOL is enabled in the BIOS. The BIOS has been upgraded to v1.1.12.
Does anyone know how WOL can be enabled for this model with Windows 7?
