Eu tenho um Intel Wireless AC 7260 na minha área de trabalho e ele parece estar funcionando bem o suficiente até cerca de uma semana atrás. Eu devo ter feito algo na linha de comando que borked meu Wifi, porém eu sou infelizmente incapaz de lembrar o que poderia ter sido. No entanto, no menu do painel, minha opção "Ativar Wi-Fi" não aparece mais e, de fato, quando eu procuro pela minha interface sem fio no terminal, ela não aparece. Parece que meu computador só reconhece a interface ethernet e o controlador de rede. Eu tentei substituir o driver de dispositivo sem sucesso. Eu sou uma espécie de noob de Linux, então não tenho certeza de quais saídas de console são necessárias para diagnosticar esse problema, no entanto, vou produzir qualquer, se solicitado. Devo acrescentar, se não ficou claro, que não há absolutamente nenhum problema com a minha conexão Ethernet.
Aqui está a saída de ifconfig -a :
