How to Turn on Your Computer via Wi-Fi: A Step-by-Step Guide with Router Setup

Have you ever wanted to turn on your home PC without leaving the couch? Or start your workstation ahead of time so it's ready to go when you arrive? Today, it's possible—and you don't need complicated smart plug systems. Just set it up correctly. remote activation via Wi-Fi (technology Wake-on-WLAN).

In this article, we'll cover all the current methods: from standard BIOS functions to mobile apps and router settings. You'll learn how to wake your computer from a signal on the local network or even over the internet—from a phone, laptop, or tablet. We'll also find out why this technology sometimes doesn't work and how to fix it.

Important: The methods differ for desktop PCs and laptops and also depend on the motherboard and network card model. We'll cover universal solutions that work on 90% of modern devices (produced between 2018 and 2026).

1. What is Wake-on-WLAN and how does it work?

Wake-on-WLAN (WoWLAN) - this is an extension of the classical technology Wake-on-LAN (WoL), which allows you to turn on your computer via a network signal. While WoL requires a wired connection (Ethernet), WoWLAN works via wireless network - This is exactly what we need.

The principle is simple:

• 🔌 The computer is turned off, but the network card remains powered (receives power from the line +5VSB from the power supply).
• 📡 The router or other device sends a special packet to the network - Magic Packet (6 bytes FF, followed by the MAC address of the target PC repeated 16 times).
• 💻 The network card "catches" the packet, compares the MAC address, and sends a signal to the motherboard. The computer turns on.

The main difference between WoWLAN and WoL is the involvement of a router. It must support the function ARP Proxy or Wake-on-WLAN (Different manufacturers have different names.) Without this, packets won't reach a powered-off PC.

2. Equipment requirements: what is needed for remote activation

Before setting up, check that your equipment is suitable. Here are the minimum requirements:

Critical note: WoWLAN is often disabled by default on laptops to conserve battery power. Even if configured correctly, the PC may not boot when running on battery power.

⚠️ Note: Some budget motherboards (especially those of the form factor Mini-ITX) do not support WoL/WoWLAN due to their simplified power supply circuitry. Check your model's specifications on the manufacturer's website.

3. BIOS/UEFI setup: enabling WoL support

The first step is to enable the feature in the BIOS. The interface may vary, but the general procedure is as follows:

1. Restart your PC and enter the BIOS (usually the key Del, F2 or Esc when loading).
2. Find the section Power Management (or Advanced → APM Configuration).
3. Activate options:
   • 🔘 Wake-on-LAN → Enabled
   • 🔘 Power On By PCI/PCIe → Enabled
   • 🔘 Resume by LAN → Enabled
   • 🔘 ErP/EuP Ready → Disabled (this disables ultra low power which interferes with WoL)

Save settings (F10) and reboot.

On laptops, look for similar settings in the section Advanced → Wake-on-WLAN or Power → Wake on Wireless LAN.

Wake-on-LAN enabled|ErP/EuP Ready disabled|Saved changes before exiting|Network card power checked (+5VSB)-->

⚠️ Note: On some motherboards ASUS (series ROG Strix, Prime) The WoL function is hidden behind additional settings. If you can't find this setting, update your BIOS to the latest version.

4. Windows setup: network card drivers and settings

Even if the BIOS is configured correctly, Windows may block WoWLAN. Follow these instructions:

Step 1: Update your network card driver

• 🖥️ Open device Manager (Win + X → Device Manager).
• 🔍 Expand Network adapters, find your Wi-Fi module (for example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA61x4).
• 🔄 Right-click → Update driver → Automatic search.

Step 2: Enable WoWLAN in the adapter properties

1. IN Device Manager Open the properties of your Wi-Fi adapter.
2. Go to the tab Power management.
3. Please tick the boxes:
   • 🔘 Allow this device to wake the computer from standby
   • 🔘 Magic Packet package only (if there is such a parameter)

Step 3: Adjust power settings

powercfg /deviceenablewake "NETWORK_ADAPTER_NAME"

To find out the exact name of the adapter, run the following in the command line:

powercfg /devicequery wake_armed

5. Router setup: Magic Packet forwarding

This is the most difficult step—without the correct router settings, packets won't reach a powered-off PC. Instructions for popular models:

For routers TP-Link (Archer, Deco, TL-WR*):

1. Go to the web interface (192.168.0.1 or 192.168.1.1).
2. Go to Advanced Settings → Network → Wake-on-LAN.
3. Activate Enable Wake-on-LAN.
4. Add a rule with the MAC address of your PC (you can find it out using the command ipconfig /all in Windows).

For routers ASUS (RT-AX*, GT-AX*):

• 🌐 Open Administration → Local Network → Wake on LAN.
• 🔧 Turn on Enable WoL and specify the MAC address of the PC.
• 🔄 Save the settings and reboot the router.

For routers Keenetic:

In the web interface:
System → Devices → [Select your PC] → Enable Wake-on-LAN

⚠️ Attention: On routers MikroTik Setting up WoL requires creating a special rule in IP → ARPIf you are not familiar with RouterOS, it is better to use alternative methods (see section 6).

What to do if your router doesn't have WoL functionality?

If your router does not support Wake-on-LAN, you can use a workaround:

1. Connect a device that supports sending Magic Packets (for example, Raspberry Pi or a second computer).

2. Set up a packet sending service on it (for example, wakeonlan in Linux or Depicus Wake-on-LAN in Windows).

3. Send a command to this device remotely (via SSH or TeamViewer).

6. Alternative ways to turn on a PC via Wi-Fi

If WoWLAN doesn't work or your equipment doesn't support it, try these methods:

Method 1. Smart socket with a timer

• 🔌 Connect your PC to a smart plug (e.g. Xiaomi Mi Smart Plug or TP-Link HS100).
• ⏰ Set the power-on timer to 1–2 minutes earlier than the desired time (to allow the PC time to boot up).
• 📱 Control the socket using an app on your phone.

Disadvantage: the computer will turn on “blindly”, without checking the OS loading.

Method 2. Remote control programs

Some applications can wake up your PC via cloud services:

• 🖥️ TeamViewer (function Wake-on-LAN in the device settings).
• 🌍 AnyDesk (requires WoL pre-configuration in BIOS).
• 📱 Unified Remote (there is a plugin for WoL).

Method 3. Cloud services (for example, WakeOnLan Over Internet)

Services like Depicus WOLi allow you to send Magic Packets over the internet. To do this:

1. Register on the service website.
2. Add your PC's MAC address.
3. Download the mobile app and send a turn-on signal from anywhere in the world.

7. Common problems and their solutions

WoWLAN is a fickle technology. Here are some common errors and how to fix them:

Problem	Possible cause	Solution
The PC does not turn on the first time	Unstable power supply to the network card in sleep mode	Check your settings ErP/EuP Ready in BIOS (should be Disabled)
WoWLAN only works when connected via Ethernet.	The Wi-Fi adapter does not support the function or is disabled in the BIOS.	Update your adapter driver or use an external USB Wi-Fi module with WoWLAN support.
The router is not sending Magic Packet	The WoL function is disabled in the router settings.	Check your settings ARP Binding or Wake-on-LAN in the web interface
The PC turns on but immediately turns off.	Conflict with fast boot (Fast Startup) in Windows	Turn it off Quick Launch V Control Panel → Power Options

Troubleshooting:

1. Check if the indicator on the network card is lit after turning off the PC (it should blink or glow dimly).
2. Make sure that the MAC address in the router settings is specified correctly (no dashes, only numbers and letters).
3. Try sending a Magic Packet from another device on the local network (for example, from a smartphone via an app) Wake On Lan).

⚠️ Note: On some motherboards Gigabyte (series B550, X570) WoL function conflicts with technology Q-Flash PlusIf your PC won't turn on, turn it off. Q-Flash Plus in BIOS.

8. Security: How to protect your PC from unauthorized activation

Remote power-on is convenient, but potentially dangerous. An attacker can send a Magic Packet to your MAC address to turn on your PC and attack it. How to protect yourself:

• 🔒 Configure it on your router MAC filtering — allow sending WoL packets only from trusted devices.
• 🛡️ Disable port forwarding for WoL in your router if you don't use WLAN.
• 🔑 Use a strong password to access your router's web interface.
• 📵 Update your router firmware regularly - vulnerabilities in WoL are periodically found (for example, CVE-2019-16746).

If you don't need to turn on your PC remotely on a regular basis, disable WoWLAN in the BIOS when not in use. This will reduce the risk of attack and save power (the network card consumes ~0.5–1 W in standby mode).

FAQ: Answers to Frequently Asked Questions

Is it possible to turn on a PC via Wi-Fi if it is completely turned off (not in sleep mode)?

Yes, but only if:

1. The motherboard and power supply maintain voltage supply to the network card in the off state (+5VSB).
2. The function is activated in the BIOS Wake-on-LAN or Wake-on-WLAN.
3. The router is configured for forwarding Magic Packet.

If the PC is disconnected from the power outlet or the power supply is not supplying +5VSB, WoWLAN will not work.

Why does WoWLAN work over Ethernet but not over Wi-Fi?

This is a typical problem if:

• Your Wi-Fi adapter does not support WoWLAN (check model specifications).
• The adapter driver is not configured (see section 4).
• The router cannot send Magic Packet over a wireless network (support needed) ARP Proxy).

Solution: Update your Wi-Fi adapter driver or use an external USB module with WoWLAN support (for example, ASUS USB-AC56).

How to turn on a PC via Wi-Fi from a phone?

Install one of these applications:

• Wake On Lan (Android/iOS) - Sends Magic Packet over local network.
• TeamViewer — if the WoL function is configured in the account.
• Unified Remote — requires installation of the server part on the PC.

To work via the Internet (not on a local network), you will need:

1. Set up port forwarding on the router (UDP 7 or UDP 9).
2. Use a static IP address or DDNS (eg. No-IP).

Is it possible to turn on a laptop via Wi-Fi if it is running on battery?

In most cases, no. Laptops turn off power to the network card when running on battery to conserve battery life. Exceptions:

• Some models Dell Latitude And HP EliteBook support WoWLAN on battery (must be enabled in BIOS).
• If the laptop is connected to charging, WoWLAN may work (depending on the model).

Check your laptop documentation for this parameter. Wake-on-Wireless LAN in Battery Mode.

How do I know if my router supports Wake-on-LAN?

Verification methods:

1. Take a look at the router's web interface and look for sections LAN, Wake-on-LAN or ARP Binding.
2. Check the model specifications on the manufacturer's website (keywords: WoL, Wake on LAN, ARP Proxy).
3. Use the support table:

   Manufacturer	WoL support	Examples of models
   TP-Link	Yes (on most models)	Archer C7, Deco X60, TL-WR1043ND
