Instalei recentemente o adaptador de rede Intel Gigabit CT na minha máquina Windows de 64 bits. Anteriormente, eu estava usando conexão sem fio e cliente Cisco AnyConnect VPN ver 3.1.0165. Ao tentar se conectar à VPN no trabalho, estou me conectando com êxito primeiro, mas depois fico desconectado e não consigo me reconectar. Este é um problema conhecido com o nosso servidor Cisco. Ele sempre desconecta e se reconecta nos primeiros dois minutos. Se eu estiver conectado ao meu roteador em casa usando conexão sem fio, tudo funciona bem. Ele é desconectado e, em seguida, reconecta-se automaticamente e permanece conectado. Mas se eu estiver conectando usando o novo adaptador Intel, ele não conseguirá se reconectar. Eu rastreei esse problema para o fato de que, quando o cliente Cisco se desconecta, ele remove minha rota de gateway padrão. Eu não consigo descobrir por que isso é feito somente se eu estiver conectado através do adaptador Ethernet e não através de wireless. Eu já tentei desinstalar e reinstalar drivers para a placa de rede. A única coisa que ajuda depois é desabilitar e, em seguida, habilitar o adaptador de volta, mas não está ajudando com a reconexão à VPN. Aqui está a configuração e as rotas antes de se conectar à VPN:

Depois de se conectar à VPN (brevemente), o adaptador VPN é adicionado:

Neste ponto, eu já perdi o gateway padrão e a conexão com a Internet. Mais uma vez, se eu conectar usando o gateway padrão do adaptador sem fio não é perdido após a desconexão da VPN. Aqui estão as configurações para o adaptador sem fio:

Alguma idéia de qual configuração está causando isso?
