last time running and NetworkManager[2714] killed by another terminal
`kill -KILL 2714`:

# /usr/sbin/NetworkManager --no-daemon --log-level=debug
[...]
NetworkManager[2714]:    keyfile: parsing ATT448 ...

The weird thing is this is only happening at home with ATT448, that is
an AT&T internet device WIFI with WPA authentication;

when I am working with other WIFI providers, I see NetworkManager
launched only one dhcpcd and running well
