Could you please expand Network Adapters in Device Manager, right-click the adapter, click Properties, click the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box.
One of my computers there is a Broadcom Netlink adaptor who has the option to "V" (activate) Allow computer to turn off this divice to safe power but it is not switched on (like you requested) but I can't get the reomote connected when the computer is in sleep mode.
If you want I can email you a screenshot
On the secound computer there is an INTEL 82579LM and there I do not have that option. There is a Enegry efficient ethernet option wich was switched ON I did switch that off and now I can get to the computer when he has rebooted but still not when he is in sleeping mode.
Just as an information ... I was a [censored] user before and never had a problem to get a connection to the computers even when in sleeping mode.
I've just tested. You can not access the computer in sleeping mode. And I am fully confident, that you can't do it through another software. Because you can't even ping a machine in sleeping mode. Network adapter is unpowered at that time.
You probably should just disable your remote computer from going to sleep.
1. Type Power Options into the start search box 2. Press enter. 3. Select ChangePlan settings next to the prefered plan that is selected 4. Set Put the computer to sleep - Never.
