[WoL] Debian host no longer wakes up

Hello,

For some reason, a Debian host no longer wakes up using NirSoft's WakeMeOnLan application from Windows.

~# ip link
00:24:21:16:bb:98

~# ethtool eth0

Put computer to sleep:

~# /usr/sbin/rtcwake -m standby -u -t $(date +\%s -d 'tomorrow 1145')

The host is shown as unavailable.

Any idea what it could be?

Thank you.

Wake-on: d

That should have been "g".

Any reason why it changed, and why it no longer works (like it used to)?

No way of knowing the reason, maybe an update?

You can change the setting by

sudo ethtool -s <device> wol g
