1/30/2024 0 Comments Wol wake on lan settings values![]() ![]() The MAC address is critical, as a PC in the off condition doesn’t have an IP address. (CCNA Intro Exam Certification Guide, Cisco Press, 2004, Wendell Odom, p34)Īt Layer 1, (the Physical layer) both the PC to be turned on and the PC sending the WOL signal need to use wired Ethernet connections.Īt Layer 2, (the Data Link layer) WOL uses MAC (Media Access Control) addresses to turn on a specific PC. As you can see in Figure 1, the OSI model specifies seven layers. To find your way through all the options, it’s helpful to reference the OSI model for computer networking. If you check your work at each step, you can avoid doing it all over again later. I have been involved in far too many network changes that had to be completely re-done due to poor testing and methodology. Trust me, you’ll thank yourself later for your patience and attention to detail now. I can’t emphasize enough the importance of making one change at a time, and then testing the effectiveness. You’ll notice that testing comprises multiple steps in this guide. The goal here isn’t to cover every aspect of Wake On LAN/WAN technology, but to provide understanding and tools to make it work on your network. This guide lists those steps, covering BIOS configurations, software, testing, routing, and security. In order to take advantage of Wake On LAN/WAN technology, there are multiple steps to perform. Certainly, your PC is more secure from hackers when it is off. Maybe you saw Al Gore’s video, and you want to conserve energy and leave your PC off except when you need it. ![]() Perhaps you have a PC at home that you don’t want to leave powered on, yet may need to access while at work. Wake on WAN is the ability to send that same signal over a wide area network (WAN), such as the Internet, to trigger power-up of a PC on a private LAN. What is Wake On LAN? Wake on LAN, or WOL, is the ability to send a signal over a local area network (LAN) to power up a PC.
