5268AC Router Wake On Lan (WOL)
Trying to get Wake On Lan (WOL) working with the 5268AC router, problem is over time the router clears the ARP cache and it stop working.
When the computer is initially turned off and a WOL packet is sent from the Internet (WAN) the computer turns on as expected. However, turning off the computer for a few hours or overnight the router's ARP cache naturally ages out ARP entry for this computer.
Then when a WOL packet is sent the router does an ARP request, however with the computer off it seems like the NIC is not responding to the ARP request and the WOL fails.
This could be a computer NIC configuration, in this case a Windows 10 Pro with a Realtek PCIe GBE NIC. There is an ARP Offload option by default is enabled, I've tried disabled without luck.
Seems like this could be solved one of 2 ways:
1.) Adding a static ARP entry in the router so it never ages out - possibly using one of the 5268AC Application Types or some other setting.
2.) Configuration setting on the NIC to listen and respond to ARP Request for its IP address.
