[SOLVED] NetworkManager constantly disconnect and reconnects

Greetings,

Since yesterday, I have been unable to get a stable connection with NetworkManager: it suddenly broke and started constantly disconnecting and reconnecting, whichever connection I use (wifi or cable). The symptoms are exactly the same as described in the following topic:

https://bbs.archlinux.org/viewtopic.php?id=259876

Including the dmesg output:

wlp3s0: deauthenticating from <censored> by local choice (Reason: 3=DEAUTH_LEAVING)

The solution didn't entirely work out for me though. It turns out I did have both dhcpcd and NetworkManager enabled, but disabling dhcpcd didn't help. I decided to disable NetworkManager instead, and use dhcpcd instead. That worked out alright.

With a working connection, I had the opportunity to check for alternatives. Turns out Wicd isn't working anymore : doesn't build, and they're allegedly still working on a Python3/GTK3 port (I haven't found any recent news though). I'll try to move to ConnMan, but I would very much like to get some clues onto how to diagnose and fix NetworkManager.

I did update my system yesterday, but I don't see which update might've broken anything related to NetworkManager. I updated again this morning to no avail.

Post a full journal covering a failing situation and your currently active services

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
sudo journalctl -b

Well... I'm a retard.

I had issues with connman, so did another reboot, and now I can't reproduce the issue...

Checking my console history, everything becomes clear.

I *disabled* dhcpcd. I didn't stop it.

Damn. Sorry for the inconvenience !
