Saída sem fio usando a placa Intel 7260AC (desautentada - Razão 7)

Question

Comprei recentemente um novo laptop e ele tem uma placa sem fio Intel 7260AC. Eu estou recebendo dropouts sem fio regulares que ocorrem em nenhum intervalo específico. AFAIK isso só ocorre na minha casa.

Coisas que tentei

• Atualize para o kernel principal mais recente (3.15)
• Atualize para os novos drivers no site da Intel (copie o iwlwifi-7260-8.ucode para o / lib / firmware e reinicie).
• Desligou o gerenciamento de energia
• Sem fio residencial comutado para WEP

Não sei o que fazer. Isso é absolutamente incapacitante em casa.

Aqui estão algumas saídas de vários registros
