Laptop unable to wake from sleep when connected to wifi

Hi, I just installed KDE Plasma and I have been using netctl/dhcpcd to connect to my wifi. I noticed that whenever I was connected to wifi, I'm unable to wake my laptop (Lenovo U31 Intel Core i3) from sleep. I just have a blank screen with no cursor. I also notice that it never really goes to sleep; the power light is still on and I have to reboot in order to start again.

I tried using NetworkManager w/ dhclient instead and the problem persists. I've tested this; every time I run

 nmcli device disconnect wlp3s0 

I'm able to wake from sleep. Otherwise, I run into my problem. What steps should I take to tackle this problem?

EDIT: Here's the journalctl output for a failed sleep:

I have been using netctl/dhcpcd

Why are you using NetworkManager as well? It looks like you missed the red "Warning" that's in the netctl Wiki about conflicting network services?

If that doesn't fix the problem, please post dmesg, journal logs, etc. that are from when you attempt to "wake up" the laptop.

Re: Laptop unable to wake from sleep when connected to wifi

I'm not using netctl, I simply switched to NetworkManager to see if anything changed. I made sure that netctl/dhcpcd processes did not run.
