How to Fix Manjaro Linux on ASUSTUF Gaming B550M Plus Not Waking Up on Wireless

Introduction

In this article, we will discuss the steps to fix the wake-on-wireless feature on a Manjaro Linux system with an ASUS TUF Gaming B550M Plus mainboard and a PCIe AX200 wireless card. We will cover the key concepts and configurations required to enable this feature.

Wake-on-Wireless Overview

Wake-on-Wireless (WoW) is a feature that allows a wireless network adapter to bring a computer out of sleep mode when it detects network activity. This can be useful in various scenarios, such as remote backups, updates, or even just to reduce the time it takes to resume using your computer.

Manjaro Linux and ASUS TUF Gaming B550M Plus Configuration

To configure WoW on a Manjaro Linux system with an ASUS TUF Gaming B550M Plus mainboard and a PCIe AX200 wireless card, you will need to perform the following steps:

1. Update your system: Before making any changes, make sure your system is up-to-date using the following commands:

   sudo pacman -Syu

2. Check your wireless adapter: Verify that your wireless adapter supports WoW by running the following command:

   lspci -nnk | grep -i network -A3

   Look for the "Wake-on" field, and ensure it includes "g". If not, your wireless adapter may not support WoW.

3. Configure the BIOS: Restart your system and enter the BIOS settings. Navigate to the "Power" or "Advanced" settings and enable "Wake-on-LAN" or "Wake-on-Wireless LAN." Save your changes and exit the BIOS.

4. Configure Manjaro Linux: Open a terminal and edit the /etc/systemd/network/wlan0.network file (replace "wlan0" with your wireless interface name) using your preferred text editor, and add the following lines:

   [Match] Name=wlan0 [Network] WakeOnLan=magic

   Save the file and exit the text editor.

5. Enable and start the network service: Run the following commands to enable and start the network service:

   sudo systemctl enable systemd-networkd sudo systemctl start systemd-networkd

6. Test the WoW feature: To test the WoW feature, put your system to sleep and then use another device to send network traffic to it, such as a ping command. If everything is configured correctly, your system should wake up.

• Ensure your wireless adapter supports WoW.
• Enable the WoW feature in the BIOS.
• Configure Manjaro Linux to enable WoW.
• Test the WoW feature.
