Code:# This is the network config written by 'subiquity'
network:
ethernets:
enp3s0:
dhcp4: true
optional: true
version: 2
wifis:
wlx984827af4e82:
dhcp4: false
optional: true
addresses: [192.168.1.10/24]
gateway4: 192.168.103.1
nameservers:
addresses: [192.168.1.1]
access-points:
"my-ssd":
password: "my-wifi-password"I tried Quote:
