I have fresh installation of Ubuntu Server 18.04. Until it is all set up and tested, I want it to be connected to both wired and wifi network.
My /etc/netplan directory contains two files:
network: version: 2 renderer: networkd wifis: wlp58s0: dhcp4: yes dhcp6: yes access-points: "MyNetworkName": password: "MyPassword"
network: ethernets: eno1: addresses:  dhcp4: true optional: true version: 2
When the server boots up, it stays for 2 minutes on this message:
A start job is running for Wait for Network to be Configured.
While this message is displayed, the server can be pinged over the wired IP, but not over the wifi IP. It can be pinged over the wifi IP right after the 2 minutes of waiting have passed and user prompt is displayed on the connected display.
When I log on, ifconfig shows that both interfaces have initialized fine: both have received their IP addresses from the router, the server is reachable over the network at both IPs.
Here's the output of
networkctl list command right after boot:
$ networkctl list IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 eno1 ether routable configured 3 wlp58s0 wlan routable configured
The wifi router is about 2 meters close, the signal is very strong. Since I don't plan to restart the server too much, the problem of waiting is bearable. But I am afraid this could be a symptom of some network configuration that should be fixed before things get bad.
