On Kubuntu 20.04 the NetworkManager is slow to connect via LAN. It is in the “Setting network address” state for about 20-30 seconds, while dhclient from console connects (obtains IP) immediately. I’m not sure what other info to include, which log files etc. to post to help resolve this. Please advice.
More info as reaction to the comments:
1) this happens even when using a single connection.
2) I’m not sure what is “Plasma KDE network manager” what I’m trying to use comes from the network-manager package.
