Wake-on-LAN was working in 19.04 just fine, then I left my computer on full time for a few weeks, now WOL no longer works to wake up my desktop from suspend mode.
The sudo ethtool enp2s0 |grep Wake command shows:
Supports Wake-on: pg
Wake-on: g
One thing I noticed though is that it might be related to the power state. Before, when my computer would suspend, the power light would slow blink blue. Now, the power light is off in suspend mode. Running cat /sys/power/mem_sleep returns s2idle [deep]. When I went through a bunch of things to set it to [s2idle] deep, all it did was make it so my computer didn't really go to sleep or WOL.
I have tried older kernel (5.0.0-15 through 5.0.0-20 and 4.14.134) with no success.
I tried editing the .yaml file in /etc/netplan as suggested here to this:
# Let NetworkManager manage all devices on this system
network:
version: 2
# renderer: NetworkManager
renderer: networkd
ethernets:
enp2s0:
match:
macaddress: 90:2b:34:ad:b5:f4
dhcp4: true
wakeonlan: true
I tried this command to show magic packets received
sudo ngrep '\xff{6}(.{6})\1{15}' -x port 9
and got this:
interface: enp2s0 (192.168.1.0/255.255.255.0)
filter: ( port 9 ) and ((ip || ip6) || (vlan && (ip || ip6)))
match: \xff{6}(.{6})\1{15}

I'm really getting stumped and need some help. Computer is set to receive WOL packets and react to them. It's receiving them, it's just not acting on them. I'm starting to do some cost calculations to see if buying new components would be cheaper than just leaving the computer on. Help please!
