Eu recentemente atualizei a RAM no computador do meu pai (Lenovo ThinkPad E545) porque ele estava reclamando que era lento. Tudo funcionou bem por um tempo, então seu WiFi morreu sobre ele.
O Windows 10 acha que um switch de hardware está desativado e todas as tentativas de executar o solucionador de problemas simplesmente me dizem para ligar o switch novamente. Todas as tentativas de ligar o interruptor foram infrutíferas, não faz nada.
Recoloquei a RAM, reinstalei a RAM antiga, recoloquei a placa Wi-Fi, desconectei e reconectei os cabos das antenas, verifiquei o BIOS e o gerenciador de dispositivos para verificar se a placa está sendo reconhecida (é) , reinstalou o Windows e até inicializou o Fedora Linux a partir de uma unidade USB (e teve problemas similares no Windows).
Então, tenho certeza que agora é algum tipo de problema de hardware (sinta-se à vontade para inserir aqui). Mas o que poderia ser? Mais uma vez, o cartão Wi-Fi é reconhecido pelo computador, então estou em uma pequena perda.
--- Editar ---
Alterei o cartão Wi-Fi e o problema permanece inalterado.
Aqui está a saída de lspci -vvv

Nenhuma maneira de ligar o Wi-Fi com este modelo no Fedora. Desde que precisa da combinação botão FN + Wifi. Já é um desafio para fazer esse trabalho, depois de um tempo, quando eu consegui ter de alguma forma o acesso ao cartão, os drivers não podem realmente lidar com este computador. Eu tentei de tudo; Se você quiser solucionar o problema, é melhor usar o Windows.
