Network.service falhou ao iniciar: Nenhum dispositivo adequado foi encontrado

Instalei recentemente a versão mínima do Centos 7 no meu Raspberry PI 3B +. Rede parece estar funcionando (eu sou capaz de ssh para isso), mas network.service está a falhar ao iniciar. Abaixo da saída do journalctl:

Minha #ip a output:

aae abaixo do meu arquivo /etc/sysconfig/network-scripts/ifcfg-wlan0 :

TYPE=WiFi PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=wlan0 DEVICE=wlan0 ONBOOT=yes IPV6_PRIVACY=no UUID=b9253d06-b892-41ad-a05b-7c49a2eebc73 IPADDR=192.168.8.210 NETMASK=255.255.255.0 HWADDR=B8:27:EB:BC:30:B5 GATEWAY=192.168.8.1 DNS1=192.168.8.1

Outra questão é que eu tenho IP duplo, apesar de ter IP estático configurado no arquivo ifcfg-wlan0, como você pode ver acima. Primeiro que é dinamicamente preenchido pelo servidor dhcp do meu roteador e segundo que eu especifiquei no arquivo ifcfg-wlan0 como IP estático. Alguma idéia do que devo fazer diferente para ter apenas um ip estático?

FYI, após a instalação do SO, não havia arquivos ifcfg, então eu tive que criar ifcfg-wlan0.
