How to turn on a PC remotely

Among the various options that Windows offers us, we find a special one, available for most operating systems, with which it is possible to turn on our computer remotely, either on a local network or, in some cases, externally. This process is known as WoL (Wake on Lan) and its mission consists of a protocol with which it is possible to remotely start the PC without pressing the typical physical power button. This is something that administrators or users must simplify a daily task..

 

 

When leaving the PC connected, the network card continues to receive power, this card must have WoL active (both in the BIOS and at the configuration level), based on this, Wake on Lan will send something called "Magic Packet" which is sent simultaneously to all the computers on the network and in it the MAC address of the destination computer. When the PC that is turned off performs the "listening" function, it will take care of receiving the magic packet and automatically the network card will send a signal to the motherboard or to the power source so that the boot process starts, We see how simple the remote start process is internally.

 

The Magic Packet is a broadcast frame where we find a string of 6 bytes with a value of 255 (in hexadecimal value FF FF FF FF FF FF) which is followed by 16 repetitions with the MAC address of the destination computer, to using Wake on Lan requires:

  • Have access to the network
  • The PC may be turned off or in sleep or hibernation mode
  • Have a point-to-point network between two or more computers

 

TechnoWikis will explain how to turn on a PC remotely and have access to this functionality..
