To 'wake up' your computer, you need to log in to the Keenetic device web interface or open the Keenetic mobile app, select the PC in a list of home network devices and click the 'Wake on LAN' button.
In some Wi-Fi devices (wireless adapter, smart TV) this technology is called WoWLAN (Wake on Wireless LAN). The computer must be in sleep mode, and it must have Wake-on-LAN enabled beforehand. A practical use case might be, for example, when you are in the office, you can remotely turn on your home PC. Wake-on-LAN is a special option of the PC's boot firmware - BIOS or, on modern systems, UEFI, that allows you to power on the computer by sending a special signal (a so-called 'magic' packet) to that computer over the local network. With a Keenetic router, it's possible to remotely turn on home network computers via the web GUI or a mobile app by exploiting the Wake-on-LAN (WOL) technology.
