Network connection doesnt connect after update

Hi, I updated my system and now I can't connect. If i disable and enable connection on gnome settings, momentarily connection  load one website but after that connection doesnt work again.
I'm writing from older installation that i dont use anymore and the connection works fine on here, also wifi connection on my cellphone.
I extracted some information that may help.

Re: Network connection doesnt connect after update

Look in your journal for NetworkManager related information.

Re: Network connection doesnt connect after update

For now I solved by disabling NetworkManager and start to use wicd, but anyway I extract my journal file from 15/05/2018, I still want to figure out what happened.

You've at least dhcpcd & NM enabled/active (which is somehow not reflected by the "find /etc/systemd" output ...)

Re: Network connection doesnt connect after update

I had a similar issue with NetworkManager a few days ago after a recent linux and networkmanager update. However, I was in a rush to do something and switched to netctl. As I have wifi connectivity now that seems reliable so far, I haven't switched back, just as the OP has switched to wicd
