Hello, so this happened yesterday morning. I couldn't connect to wifi at school, but didn't think much of it as things like this sometimes happen (could've been problem on their side, or simply weak signal) and I wasn't using laptop later that day. Today, at home, same problem and LAN doesn't work either.
Now I know it's not just temporary, or even hardware issue. Phone can connect to router wifi without problems and live distro on laptop works well too. The only thing I can recall doing prior to this problem, is system update, altho everything seemed to work fine right after..
Network interface info shows that both interfaces are down, but turning them on does nothing.

Dmesg output after trying to connect to wifi shows 'Reason: 3=DEAUTH_LEAVING', which brought me to one topic on this forum. Trying few methods from there didn't help.

try disabling all network related services like netctl, wpa_supplicant, dhcpcd, networkmanager etc.
then reenable network manager.
e.g.
# systemctl disable netctl
# systemctl enable NetworkManager
then reboot your system and try connecting again.

Unfortunately, that didn't help. Good thing is LAN actually works, but only right after restart. After re-plugging the cable, system won't connect again.
Another thing I tried, was downgrading some packages which got upgraded earlier, but no success either.

Please post the output of:
ls -l /etc/systemd/system/multi-user.target.wants
Have you tried connecting manually?

I tried connecting manually using wpa_supplicant, didn't work.

I hope you didn't just type in the example JJK wrote as it was only an 'example'. You needed to modify with correct spelling of the service and capitalization. https://wiki.archlinux.org/index.php/Wi … atic_setup
"There are many solutions to choose from, but remember that all of them are mutually exclusive; you should not run two daemons simultaneously"
This means you cannot have NetworkManager.service, netctl-auto.service, dhcpcd.service all started. They are all part of the fight club. They will fight over each other. Only use one.

I was using netctl some time ago, but not anymore. Don't know why those links stayed there..
I honestly thought dhcpcd worked together with NetworkManager, even in config file for NM I set it to use dhcpcd and it was working fine. Now I read somewhere that NM is using dhclient, so I just changed that option, restarted NM service and it all finally started to work. So there's a good ending to this story.
Thanks for your time.
