Wake on LAN Issue

[bebens]

I've configured WOL on a target computer and it seems that for first 20 minutes or so the target is asleep, I can wake it remotely.  So I assume my configuration is correct.  However, if the target is a sleep longer than that, the target computer will not wake up. The computer is not set to hibernate.  I'm using a Win 10 on the target and Win 7 on the partner.

The bios setting is set to WOL for S5 and S6 sleep states.

Does anyone have any thoughts as to what is happening the longer the computer is sleeping?  What exactly is changing?

Another question I have - does the Windows firewall have to be configured to allow traffic on Port 9?  I don't see any reference for this firewall setting in the Team Viewer WOL manual.

check power settings to see when things like drives sleep, or Network adapters power down...

Not heard of port 9 needing to be open.

I normally don't have to configure windows firewall at all for Teamviewer
