Boa noite!
Sou novo no linux e estou com problemas na internet.
Sei que a internet está funcionando pois em outros dispositivos navega normalmente, e as vezes uso o comando ping e retorna os pacotes, porem quando vou navegar via chrome ou firefox, ao digitar um site, demora um tempo para abrir, algumas vezes da erro de conexão, ai passa uns 8 segundos a pagina recarrega e funciona (algumas vezes incompletas).
Percebi que quando dou o comando ifconfig, aparecem varias interfaces (conforme abaixo) .
Vocês sabem o que podem ser estar interfaces que aparecem ? E pode ser que o erro seja na configuração do DNS?
Como forma de solucionar, realizei alguns procedimentos para alterar o dns, possui algum comando para resetar toda a configuração de rede?
Outro ponto eh sobre a tabela de roteamento, ela esta conforme abaixo. Está correta?
