WIFI_PWR_ON_AC/BAT

WIFI_PWR_ON_AC=off
WIFI_PWR_ON_BAT=on

Sets Wi-Fi power saving mode. Adapter support depends on kernel and driver. Possible values:

  • off – disabled

  • on – enabled

Default when unconfigured: off (AC), on (BAT)

Hint: deprecated config values 1=off/5=on are supported for backwards compatibility.

Note

Power saving mode can cause an unstable Wi-Fi link.

WOL_DISABLE

WOL_DISABLE=Y

  • Y – Disable Wake-on-LAN

  • N – Do not disable Wake-on-LAN (keep BIOS default)

Default when unconfigured: Y

Note

  • After changing to WOL_DISABLE=N a reboot is required to make the new setting effective (or use sudo ethtool -s <interface> wol g in a shell).

  • Your laptop’s BIOS may have an option for Wake-on-LAN too. Some vendors even allow to configure Wake-on-LAN on AC only. If you choose the BIOS option, leave WOL_DISABLE=N.
