You can then use one of the many fancy power plugs that you can access from even the internet to turn the machine on. The power difference is very minor.Ī much better way to accomplish this is to use the option in most bios that let will boot as soon as it sees power. In general you can just use one of the many sleep states where the machine is just very slowed down. If it gets in the wrong mode it will not wake on these packets. They got involved and have a bunch of proprietary sleep things that some bios manufactures actually support. I know asus routers you can remotely access the router from the internet and then tell it to send a real wake on lan packet on the internal lan. I don't know if alexa has the ability to send a actual wake on lan packet. This is why real wake on lan sends a broadcast packet not a data packet to the mac address of the machine. Since the wake on lan machine does not respond to arps there is no way for the router to know where to send the data. After about 15 minutes or so this is purged. If there is a setting in bios, Wake on Lan does have to be enabled in bios. It works at first because there is a ARP table entry cached for a period of time in the router. Device Manager>expand network adapters>right click on your adapter>select properties>power management tab> check box next to allow magic packet to wake computer. If they did they would find out it has the problem you describe. Most the idiots that write these guides have no clue and do not test properly. They want to get their clicks on their silly pages so they don't admit even if they know that it will not actually work. Everything you see related to waking stuff up from device on the internet is a hack, and the vast majority of the instructions skip the fact that it will never work unless your router has the ability to set a static arp table entry. For example, if the client address is 192.168.1.12, the broadcast address used in the packet would be 192.168.1.255.First thing to remember is there is no such thing as wake on WAN. It may be necessary to change the address to broadcast the packet to the whole network. If an IP address is specified in the magic packet, then the network switch may not properly broadcast it to the whole network.Confirm that the MAC address used in the magic packet matches the MAC for Ethernet 1 on the client system.Confirm that the client system can be pinged by the system that is sending the magic packet.These settings can override the BIOS in Windows 8 or Windows 10. Check the NIC driver properties in Windows and ensure that WOL is enabled there.There is some interaction between the BIOS settings and the NIC driver settings in Windows 8. It may be necessary to boot to the Windows desktop after changing the BIOS settings in order for them to be properly applied.This power saving setting turns off the NIC. Ensure that Deep Sleep is disabled in the BIOS (not applicable to all systems).Ensure that WOL is enabled in the BIOS under Power Management settings.If there is no link light, then there is no way for the NIC to receive the magic packet to wake the system. Confirm that the link light remains on when the system is powered off.WOL does not work when the system is running on battery. Confirm that the AC power is plugged in.Once you have confirmed that the network cable is connected to the NIC on the system, if Wake On LAN still doesn't function properly, troubleshoot using the following steps: Expand Network adapters in the device tree, select your Ethernet. Ensure that any USB NIC Adapters are WOL capable, before any troubleshooting of the system. Enabling Wake on LAN on Windows 10 Press Windows key + X to bring up the hidden quick access menu and select Device Manager. Systems without an integrated network jack will need a USB Dongle that is WOL compliant. NOTE: Most modern systems are equipped with a RJ-45 network jack.
