Wake on LAN - XPS 9720
I'm trying to activate Wake on LAN on a DELL XPS 9720.
I have activated in BIOS "LAN with PXE Boot" . Also "Wake on AC" and "Wake on USB-C Dock"
In Windows 11 , for wireless card 6E AX211 , I have enabled "Wake on Magic Packet" and "Wake on Pattern Match".
Also in Power Management tab I have checked "Allow this device to wake up the computer" and "Only allow a magic packet to wake up the computer" .
Also in Power Options , in Shut-down settings , I disabled "Turn on fast start-up"
Sending a Wake-up package to the laptop does not wake up the laptop ( from hibernate state on complete shutdown )
I also have a docking station , I tried with a UTP cable directly from the router , still nothing .
No Events found!

I solved the problem. I'm using the docking station for this , with an internet cable from the router . The docking station has an internal network card ( Realtek USB GbE Family Controller - for this one you need to activate the magic packet options again) . This one can provide the internet via USB-C cable of the docking station to the laptop ( you can even disable the wireless card ) . However this changes the MAC of the network card of the laptop in the network ( it is not the same like with the internal wireless card ) - you can see the new MAC usually on the router , when you check the devices connect to the router. When sending the Wake Up - Magic packet , you need to send it to the MAC related to the docking station , not to the MAC of the wireless card . To check if the magic packet arrives at the destination , install wireshark on the laptop and put a filter on wol (wake on lan ) . You need also to select "LAN Only" instead of "LAN with PXE Boot" in BIOS . After that it works.
