Desconexões sem fio do wifi / reconecta

Question

Estou assistindo /var/log/syslog porque minha experiência de navegação na Internet é infeliz.

Eu corri sudo apt-get update e sudo apt-get upgrade para ter certeza de que sou o mais atualizado possível. Este ciclo começando com wpa_supplicant e terminando com o evento de link enviado acontece cerca de uma vez a cada 20 segundos.

Reiniciando o roteador e o Wi-Fi, a reinicialização da máquina parece ter sido esclarecida.
