Hi list, I've installed C8 on my workstation. I configured my network devices (two bridges, two nics) using nmcli. Now that NM is the default I tried it. On C7 I always disabled it. I noticed some problem: 1) During the boot, also if NetworkManager-wait-online.service status is OK, I noticed that opening a terminal and ping some address it needs some time to perform ping and any operation on a network connection. So seems that in the first 30sec/1min there isn't an available network connection. After this time if I run a ping or whatever network is available. 2) Due to the problem 1, It cannot mount samba shares on boot saying "Not suitable address found". After the network is available I can mount samba shares. 3) I noticed that with NetworkManager a bridge must have an address. If I don't specify an address for the bridge, NM will try to assign some address, enable the connection? forever (reporting errors in messages and on notification bar). 4) NetworkManager-wait-online slow down? boot time and network availability. To solve this problem I installed network-scripts and disabled NetworkManager but I don't understand why NetworkManager need so much time to enable a connection. Can someone point me in the right direction? Thanks in advance.

I can say that they have an entry in fstab and I have several mnt-share.mount unit as generated.

From the CLI, do "nmcli con mod <device> ipv4.method disabled ipv6.method ignore". -- Chris Adams <linux at cmadams.net>

This is different from having method disabled?
