Wake On Lan

February 14th, 2012 by Luke

Short version: A new application is available for download that allows you to wake PCs across the LAN using magic packets. You need the LAN IP & MAC address of the target PC, and you need to enable wake by magic packet on the target PC. You can download the application from here.

Wake On Lan is an application I developed that sends a “magic packet” to the sleeping PC in order to wake it up. You can read more about the magic packet/wake on lan technology here.

You will need to ensure that wake by magic packet is enabled on your PC and that the PC does not turn off the network card when it goes to sleep. This can be activated in some cases by the BIOS, in others by the PC, either way I recommend ensuring you have the latest drivers for your network card. It can be a bit fiddly on some setups to configure, and there is no straight forward one size fits all guide; but in cases, like mine, it is worth setting up.I have a media PC that sleeps when it has not been used in X amount of time. When I am on the other side of the house I want to be able to access media without having to go back over the other side to wake the PC and this is where this application comes in. As mentioned you need the LAN IP and MAC address of the target PC, both of these are obtainable on a Windows PC by running “ipconfig /all” from the command line. Once you entered this data into Wake On Lan it will remember it for next time.

        I was able to download it by copying the link, pasting it into the address bar and changing the .exe to be .jar … earlier in the description you described using the .jar, plus listed the java run-time as a dependency, so I tok a stab in the dark and it worked πŸ™‚

        On the flip side, your previous page button is not working in FireFox 35, but it does work in Chrome 40.
