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.
