What Is Remote Wake-Up (RWU)?

Wake up and smell the coffee." If you've ever left your computer on, only to return later to find it turned off, you know how frustrating that can be. With Intel's Remote Wake-Up feature, all of that is a thing of the past! Remote Wake-Up is a feature of Intel's Wired for Management network specification. It allows network administrators to send magic packets containing the MAC address of their computers. Those computers will wake up from their sleep mode, enabling administrators to access them remotely. That way, they can remotely check on their network and ensure everything's okay without manually turning on each office computer before leaving for the day or even reminding employees to do so. So stop forgetting about turning on your computer before bed—use Remote Wake-Up instead! Dreaming of waking up your computer from across the globe? Well, you're in luck! Remote Wake-Up (RWA) is a feature that allows you to wake up your computer from afar. It's a handy feature when you need access to a device and the physical means to do so. Remote Wake-Up will work if the magic packets are sent from one computer on the same local area network (LAN) or within the current network subnet. However, exceptions make it possible to remotely wake a laptop outside its LAN. It is also a helpful feature that allows you to remotely trigger your computer to turn on and boot up. It can be beneficial when you need to access your computer from afar or if it is located in an area where it would be inconvenient to walk over and push the power button. What does it mean for a remote wake-up to succeed or fail? What steps can you take to ensure that remote wake-ups work as intended? And why do some users have trouble with them?
