WOL problem on NVX
I am trying to use the WOL function on a NVX If the NAS powers down, either by pressing the power button or using the built in power timer, then the WOL works if the packet is sent within a few min...

In your case I would want the router to use the DHCP reservation information (since it includes the mac address/IP address binding) - meaning it shouldn't ever need to send an ARP request for that device. The only reason I can think of to send the ARP would be to find which LAN port of the router is the correct one to use to reach the device. That is a small optimization (without it, the router needs to wait until it receives a packet from the device).

I'm using the ReadyWOL addon on my Duo, and if the computer is switched off and powercable taken out, it won't respond to WOL packets. The NAS is connected directly to my router, while my computer is connected to a Netgear switch of some kind (can't remember model atm).
The router shouldn't flush the ARP info even though I'm connected through a switch should it?
It seems unlikely that the router would handle switches differently. Though as far as I know, there is no standard behavior on ARP caches.
On your computer, there might be bios settings related to WoL.
BTW, what I'd really like to see is a WoL facility built into the router UI. That would avoid a lot of these issues.
