+# ethtool Role
+
+Installs ethtool and configures Wake-on-LAN (WoL) via a systemd service.
+
+## Variables
+
+```yaml
+ethtool_wol_interface: "eth0"  # Network interface to enable WoL on
+```
+
+## Usage
+
+```yaml
+- role: "ethtool"
+  vars:
+    ethtool_wol_interface: "enp0s25"
+```
+
+## Enabling Wake-on-LAN
+
+Three steps required:
+
+### 1. BIOS Configuration (manual)
+
+**ThinkPad:**
+1. Reboot → press `Enter` then `F1` at Lenovo splash
+2. **Config** → **Network** → **Wake On LAN** → `AC Only` or `AC and Battery`
+3. `F10` to save
+
+**Other systems:** look in BIOS under **Power** → **APM** or **Advanced Power Management** → **Wake on LAN**.
+Also disable **ErP/EuP Ready** to keep NIC powered during sleep.
+
+### 2. Ansible (this role)
+
+Enables WoL on the NIC via ethtool on every boot. Add to your play with the correct interface:
+
+```yaml
+ethtool_wol_interface: "enp0s25"
+```
+
+### 3. Suspend the host
+
+WoL is most reliable from suspend (S3). Shutdown (S5) requires BIOS "WoL from S5" support.
+
+```bash
+systemctl suspend
+```
+
+## Sending the Magic Packet
+
+From another host or FritzBox UI (**Home Network → Network → device → Wake on LAN**).
+
+## Verify WoL is enabled
+
+```bash
+ethtool enp0s25 | grep Wake
+# Wake-on: g   ← means WoL is active
+# Wake-on: d   ← means WoL is disabled
+```
