Este é o meu primeiro post aqui. Por favor, tenha paciência comigo: sou totalmente novo no Ubuntu e na codificação em geral.
Eu tenho o Ubuntu 16.04 LTS instalado no meu Lenovo IdeaCentre AIO 510. Meu Wifi parece estar bem conectado. Antes de minhas experiências com o Ubuntu, minha conexão é geralmente excelente e nunca tive problemas no Windows. No entanto, tenho navegadores Firefox e Chrome no Ubuntu, e os dois frequentemente param de se conectar à Internet. Às vezes, apenas por alguns segundos e até cerca de 10 minutos de cada vez. Em seguida, ele será reconectado e, muitas vezes, desconectará novamente alguns minutos depois.
Eu sei que existem algumas perguntas parecidas com as minhas, mas tentei várias das soluções recomendadas e não consigo fazer nada funcionar para mim. Por que valeu a pena, pensei em postar em outra questão.
Deixe-me saber quais informações posso fornecer para você. Vou começar com o seguinte:
