I've never used nmtui (I didn't even know about it). This the config that I use when i visit my parents (I use a static address at home so this corresponds to your use-case). It has to be in 0600 mode for NM to use it. # cat /etc/NetworkManager/system-connections/mumdad [connection] id=mumdad uuid=da59ada3-1349-49fe-b63b-bc68f67b6f89 type=802-11-wireless [802-11-wireless] ssid=number96 mode=infrastructure security=802-11-wireless-security [802-11-wireless-security] key-mgmt=wpa-psk psk=xxxxxxxxx [ipv4] method=auto dns=8.8.8.8;8.8.4.4; [ipv6] method=link-local You have to have "plugins=keyfile" in the "[main]" section of "/etc/NetworkManager/NetworkManager.conf" for the above to work.
