Laptop won't start with Wakeup-On-Lan

English Install/Boot/Login

Originally i had Leap 42.3 installed on my Lenovo T410 and I was able to boot that machine with my iPhone and other laptop by sendind it a “Wakeup-On-Lan”. In my other laptop i’m using the “wol” command, on my iPhone some “WOL” app.

The T410 is on my ethernet, the iPhone and other laptop are on my WIFI network (with a TP-LINK) router in between.

After upgrading the T410 from Leap 42.3 to Leap 15 the Wakeup-On-Lan doesn’t work anymore.

I’m not sure what change did cause this, sine i believe it is a BIOS setting on the T410 that enables it (it till is enabled) and i didn’t change anything on my iPhone. Still the laptop does not even power on.

Only thing i can think of is that my T410, when it goes down or suspends, it somehow tells my laptop to ignore WOL packets ???

To answer my own question:

i didn’t realize that Wakeup-On-Lan is disabled at the OS level (even if it is enabled at the BIOS level).
# ethtool eth0 showed it as disabled.

Enabling it (for broadcasts = b) did the trick for me:
# ethtool -s eth0 wol b

I feel a bit stupid after this … :open_mouth:
