Talk with this PC's maker about this. It's possible they didn't test for that function or feature.
Trying to Wake On Lan over the internet from Sleep Mode with a Magic packet. Running Windows 7 Ultimate, have Intel Ethernet adapter, wake with Magic Packet enabled. Have port 7 forwarded to computers IP address on E3000 Cisco router. Using "Awaker" on Windows Phone with all settings correct.
This will work for the first 2-3 minutes after the computer has gone into sleep mode. After it has been asleep for around 5 minutes, then it will NOT wake without keyboard action. Once put into sleep mode, it will wake over Lan again, untill it has been asleep for around 5 minutes again, same thing.
Anyone have any ideas?
