[SOLVED] dhcpcd upgrade makes wifi constantly disconnect

Hi All,

After I upgraded from dhcpcd-6.11.5-1 to dhcpcd-7.0.1-1 my wifi connection  is constantly disconnecting.
There's an error message in NetworkManager logs:

NetworkManager[568]: <warn>  [1522478420.8553] dhcp6 (wlp3s0): failed to start client (-98)

Full NetworkManager log:

Reverting dhcpcd to the older version fixes the issue.
I would appreciate any help on how to narrow down the problem to help resolve it.
Thanks.

Re: [SOLVED] dhcpcd upgrade makes wifi constantly disconnect

NetworkManager [...] dhcpcd

You're not supposed to run concurrent network managing services - they start a race and things will go south:

systemctl list-units | grep -iE '(wicd|dhcp|net|conn)'

Re: [SOLVED] dhcpcd upgrade makes wifi constantly disconnect

Thank you.
I didn't know that dhcpcd is like a network manager. I though NetworkManager uses it as a dhcp client.
Disabling dhcpcd resolved the issue.
