Bom dia a todos,
Minha conexão Wi-Fi tem sido bastante sombria desde ontem; é funky porque tudo começou comigo tentando converter um vídeo em VLC (a correlação não é muito clara para mim, embora quando vlc eventualmente não conseguiu fazê-lo e apenas parou, o wifi funcionou novamente).
Por isso, ele simplesmente não conecta, e às vezes funciona e o wifi funciona, e às vezes ele simplesmente pára de funcionar, mas fica conectado.
Definitivamente não é um problema com meu roteador, porque todos os outros computadores e dispositivos estão funcionando perfeitamente.
Além disso, a mesma coisa está acontecendo se eu inicializar com o Windows (eu particionei meu HDD em duas partes, uma com o Ubuntu 16.04 e outra com o Windows 10).
Meu palpite é que talvez a placa wifi esteja falhando em mim? está lenta mas seguramente parando para cumprir seu dever? O que é que vocês acham?
Aqui está um monte de infos que você pode precisar entender o problema (desculpe, eu simplesmente não ...), e que outro tópico sugeriu colocar.
( Minha conexão sem fio / WiFi não funciona. Que informação é necessária para diagnosticar o problema?
Desculpe se é um pouco de confusão aqui, eu estou colocando tudo ...
muito obrigado antecipadamente!
(falta algumas informações que eu corto por causa do número do personagem)
