driver de .ucode não é carregado no Debian

Question

Eu coloquei meu arquivo .ucode na pasta / lib / firmware. Na inicialização, o Debian me escreve:

Muito obrigado pela sua resposta!

Isto é típico para o kernel std deb, ele irá procurar por uma versão e falhar em carregá-la até encontrar uma válida e irá carregar essa.

por exemplo, no meu arquivo de log;

23 de outubro de 16: 39: 43 kernel mike-laptop4: [7.432898] iwlwifi 0000: 03: 00.0: carga de firmware direto para iwlwifi-7265D-24.ucode falhou com erro -2 23 de outubro de 16: 39: 43 kernel mike-laptop4: [7.432921] iwlwifi 0000: 03: 00.0: carga de firmware direto para iwlwifi-7265D-23.ucode falhou com erro -2

(Eu tenho iwlwifi-7265D-22.ucode mas não 23 ou 24 no meu diretório de firmware)

Então, por algum motivo, se o seu Wi-Fi não está carregando, não está encontrando a versão correta do firmware.

Eu sugeriria verificar o kernel wifi para um download de firmware.

você pode rodar o lspci para verificar o seu chip wifi, então você pode baixar o blob de firmware apropriado baseado na versão do kernel e no cartão wifi.

também há algumas boas dicas sobre gerenciamento de energia.
