Subject: wake-on-lan

Hi Michal,

This is my network card:

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
	Subsystem: Realtek Semiconductor Co., Ltd. Device 0123
	Kernel driver in use: r8169

On the Realtek website (https://www.realtek.com/en/products/communications-network-ics/item/rtl8168e) it says that both wake-on-lan and remote wake-on-lan are
supported. I got the wake-on-lan from my local network working, but I have problems getting the remote wake-on-lan to work.

When I set 'Wake-on' to 'g' and suspend my system, everything works fine (the router does lose the ip address assigned to the mac address of the system). I
figured the SecureOn password is meant to forward magic packets to the correct machine when the router does not have an ip address assigned to a mac address,
i.e. port-forwarding does not work.

Ethtool 'Supports Wake-on' gives 'pumbg', and when I try to set 'Wake-on' to 's' I get:

netlink error: cannot enable unsupported WoL mode (offset 36)
netlink error: Invalid argument

Does this mean that remote wake-on-lan is not supported (according to ethtool)?

---

I also tried to set 'Wake-on' to 'b' and 'bg' but then the systems turns back on almost immediately for both settings.

---

Hope you can help getting the remote wake-on-lan to work,

Best regards,
Mischa.
