Ubuntu Server 20.04 WiFi Соединение

Question 1

У меня есть Ubuntu Server 20.04, установленный в ноутбуке Compaq. При подключении подключается к Интернету. Я пытался подключить его через Wireless без успеха. Я прочитал ряд статей на использовании NetPlan онлайн и попробовал их инструкции без успеха. команда: «IP A» производит следующий вывод.

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

    link/ether 00:1f:16:d1:af:b7 brd ff:ff:ff:ff:ff:ff

    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

Может кто-нибудь, пожалуйста, помогите мне поднять интерфейс WLS1 '? Или здесь еще одна проблема?

Спасибо. оу.

Команда «IWConfig WLS1» получена следующим образом:

wls1      IEEE 802.11  ESSID:off/any

Question 2

Для работы беспроводной сети в серверной установке необходимо установить wpasupplicant .

Использование проводного соединения ...

sudo apt update

sudo apt install wpasupplicant

reboot

Ваш / etc / netplan / *.yaml должен выглядеть ТОЧНО так:

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# 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:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: true
      optional: true
  wifis:
    wls1:
      dhcp4: true
      access-points:
        "A-----66a":
          password: "7m-----k8y"

Затем создайте /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg с содержимым:

network: {config: disabled}

Затем:

sudo netplan generate

sudo netplan apply

reboot
