Eu tenho lutado com um problema estranho com o meu NetworkManager no Ubuntu 17.04 por talvez 3 meses.
Minha rede Wi-Fi congela e interrompe o trabalho a cada 30 minutos a 1 hora. Eu tentei reinstalar o Ubuntu e desinstalar o Windows, mas nem ajudou. Quando isso acontece, não consigo procurar por sites, mas se eu pressionar F5 para recarregar uma página, ela tentará recarregar para sempre. Então eu tenho que desligar o NetworkManager e se eu estiver fazendo isso, meu computador irá congelar por 5 segundos. Depois disso, posso me conectar ao meu WiFi novamente e tudo funciona normalmente por cerca de 30 minutos.
Além disso, isso acontece em todos os roteadores, independentemente de ser um hotspot, WiFi universitário ou WiFi doméstico.
A propósito, tive que reiniciar o NetworkManager 3 vezes nos últimos 5 minutos.
