Wifi não funciona no MX Linux 21.1

[Vinicius]

Comecei a usar o MX Linux a algumas semanas e no início o wifi nunca deu problema; porém, hoje ele começou a apresentar o seguinte problema: após alguns poucos minutos o wifi simplesmente para de funcionar, ele funciona na inicialização mas depois de uns 5 minutos não funciona mais, não conecta na minha rede e nem procura por outras redes.

Verifique se o gerenciamento de energia esta ligado, com o utilitário iwconfig, executando no terminal, encontre a sua interface wireless e certifique-se, que à linha Power Management: , apresentar on, ou seja ligado, tente desativar executando o comando abaixo.

sudo iwconfig <INTERFACE> power off

Se talvez funcionar considere desativar de modo permanente, editando o arquivo /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf e adicionando ou alterando, com os valores seguinte.
