depois de instalar o Ubuntu 16.04 meu novo Laptop (Asus P2520LA) Eu não posso resolver um problema que eu tenho com o meu wlan / internet, então eu ficaria muito grato se você pudesse me ajudar.
O problema é que depois de conectar com sucesso ao meu wlan, depois de algumas horas a internet cai de repente enquanto eu estou apenas navegando em um site ou algo assim. A conexão wlan ao meu roteador parece permanecer intacta, mas a internet desapareceu. (O ícone "conectado" na barra superior não muda, mas um ping não é possível).
Depois disso, uma reconexão wlan não é possível (através do ícone) e a única possibilidade que encontrei para reconectar é reiniciar ou remover e adicionar meu módulo de driver:
sudo modprobe -r rtl8821ae && sudo modprobe rtl8821ae
Em este tópico foi publicado um script que coleta informações relevantes para problemas de wlan, portanto, aqui está a saída do script executado logo após a queda da conexão com a Internet:

Há outra coisa estranha que notei que pode ser relevante: depois que a Internet caiu, posso me desconectar do wlan por meio do ícone, mas não consigo me reconectar. Mas depois de executar o script de análise, as reconexões funcionam bem.
Eu ficaria muito feliz se você pudesse me ajudar com este problema. Se você precisar de qualquer outra informação, diga-me e eu postarei.
Obrigado!
EDITAR:
Depois de mais algumas pesquisas, encontrei alguns posts / artigos que descrevem exatamente o mesmo problema que eu:

Infelizmente, em alguns posts o problema permanece sem solução e em alguns outros, onde as soluções são postadas, as soluções não funcionam para mim, então eu realmente conto com a sua ajuda.
