You're facing issues with Wake-on-LAN on your old laptop. It seems the problem might be related to your network adapter or configuration, possibly affected by changes when you boot from USB or restart. The fact that it works in the terminal but not during normal startup suggests a configuration or driver issue rather than a hardware fault.
It varies. Make sure your network card setup and BIOS WOL options are correct. Likely the issue is your router isn't compatible with WOL. First, when you want to turn on the computer, it needs its MAC address. This is recorded in the router's ARP table and assigned automatically when the computer starts up. Once you turn off the computer, most routers remove that ARP entry after a short time (about 2 minutes), so they can't wake it again. Your router simply doesn’t remember the connection. TP-Link routers include ARP binding by default, which permanently links a MAC address to an IP. This means the router doesn’t check for power or connection status—it already knows the IP associated with that MAC. Other approaches exist, like using internal WOL (common in Asus models) or creating ARP bindings via telnet (though not all routers support this). If your router is from Linksys or Cisco, the situation is usually fine. Remember, ARP binding differs from DHCP reservation: DHCP assigns an IP for future use, while ARP binding creates a direct link. I tried to simplify the explanation for your understanding.
I have Windows installed on my PC with Windows 10, and it functions correctly on the same router (Netgear Centria WNDR4700). I mostly tried assigning a MAC address, but it seems more like DHCP is handling it. I haven’t seen any ARP settings. I have a spare TP-Link router at home, so I’ll test it next. You did a good job, and your English isn’t my first language.
Certain Netgear routers support telnet, and you can locate guides online. If the second machine functions, it suggests its power-off mode maintains a link to the router.
