Outra coisa que notei é que as teclas especiais para ajustar o brilho da tela mostram o mesmo comportamento.
A atualização do debian stretch para a versão buster (teste) corrigiu o problema para mim.
Editar: Se você não deseja atualizar para uma distribuição de teste, também há a opção de instalar um kernel mais recente por meio de stretch-backports . Depois de atualizar meu
/etc/apt/sources.listde acordo, instalei o kernel mais recente disponível e o wifi funciona na inicialização agora. Também pode ser necessário instalar a versão backports do iwlwifi .Concluindo: o problema era devido a um kernel desatualizado.
