I am trying to use the WOL function on a NVXIf 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 minutes of removing the power.However if I leave the NAS overnight then the WOL function does not work.The only way to power on is via the power switch or using the power timer.Is there some sort of backup battery that is failing or is my unit faulty?I am using the latest release of the firmware.

One thing I have discovered with my computer if the power fails (which I usually turns on with WOL), it won't turn on with WOL anymore. This might be related to the ARP table on the switch you have hooked your NAS (or in my case, the computer) as it seem to remove the ARP table setting that the computer is hooked onto that specific port, which means that the switch doesn't know where to send the WOL packet.This is probably an issue with low-end switches. This problem is solved when the computer (or the NAS in your case) activates a service and requires switch activity and updates the ARP table of the switch. It's weird in your case that this happens when you only shut it down. Removing the power-cable will be an issue though.If you try and remove the power-cable, and replug it after a minute or so, and see if the network-indicator on your NAS is active, or if it blinks on the back of the unit. If the lamp on the network-card doesn't blink its most likely that the NAS doesn't boot the network card so its capable of receiving WOL packets. Hope this is of any help, and feel free to ask if anything is unclear

Thanks for that, looks like a good place to startI will check tonight when I get home.Like you say it seems likely that the ARP is getting flushed and it doesn't know where to send the magic packet.My setup is WAN side of ADSL Modem connected to Belkin cable router connected to Netgear GS116 switch which is connected to the NAS.

Please let me know if you figure it out :)

No success last night.Tried fixing the IP in the router, changing the port forward IP to the broadcast address and plugging the NAS straight into the router switch bypassing the Netgear switchAfter about 15 minutes from power off, no WOL, the network light on the switch is still lit, just no packet seems to get through.

I guess its the ARP issue.. did your router accept port forwarding of the magic packet over the broadcast-address?Fixing the IP won't do much other than defining an IP for your router to forward the port to. WOL uses mac-addresses to fire up computers or units.

Yes it seemed happy enough.

My internal IP range is 192.168.1.xx, mask 255.255.255.0. So i assume the broadcast address is 192.168.1.255

The broadcast address would be 192.168.1.255

Are you sending the WoL over the internet? Or is this failing on the local LAN? If this is not going over the internet, then there is no need to do any forwarding.

Yes, trying to send WOL from internet so I am port forwarding to the broadcast address.

Still won't wake up though.

Maybe install wireshark on a PC on the LAN, and see if the WOL message is in fact being forwarded.

Thats not a bad idea. Just remember to shut off any firewall on your computer. WOL packets should be able to travel to a broadcast address, but as I stated earlier, I'm not sure if your router forwards the port correctly.

What kind of router do you have? And which port are you forwarding?
