На Raspberry Pi 3b - проблема с wifi.
Вывод ifconfig:

Хочу подключиться к wifi - сначала пробовал задать свою сеть в
/etc/netplan/50-cloud-init.yaml
Получилось следуюшее:
# 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:
eth0:
dhcp4: true
optional: true
version: 2
wifis:
wlan0:
dhcp4: true
optional: true
access-points:
" my ESSID":
password: "my_pwsd"
- затем
sudo netplan apply - перезагрузил малину. Не помогло.

Далее, как второй вариант, пробовал через nmcli подключиться, но проверяя стату устройств увидел такое:
nmcli dev status
выдает следующее:
DEVICE TYPE STATE CONNECTION
wlan0 wifi unavailable --
eth0 ethernet unmanaged --
lo loopback unmanaged --
Устанавливал Network-Manager - выдает ошибку при попытке работы с интерфесом:
systemctl start NetworkManager

Смотрел:

Самой малине назначина статика на dhcp сервере (если вдруг это важно)
