sudo vi /etc/netplan/50-cloud-init.yaml에서 SSID랑 password입력 해주면 되는데, 그럼 매번 재부팅할 때마다

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        enx00e04c6802e2:
            dhcp4: true
            wakeonlan: true
    version: 2
    wifis:
        wlp2s0:
            optional: true
            access-points:
                "SSID":
                    password: "password"
            dhcp4: true

sudo ip link set wlp2s0 up 이걸 해줘야 합니다.
자동으로 up되게 해주려면 sudo vi /etc/network/interfaces으로 interfaces file을

auto wlp2s0

iface wlp2s0 inet dhcp

        allow-hotplug wlp2s0

        wpa-ssid "ssid"

        wpa-psk "password"

이런식으로 바꿔줘야 합니다.
