Eu tenho um adaptador WiFi 802.11b / g / n Realtek RTL8188CE no meu computador. Hoje eu atualizei para 13.10 e não consigo me conectar. Antes de atualizar o WiFi funcionou muito bem. Eu posso ver redes WiFi, mas apenas dá o erro "A configuração IP não estava disponível" ao tentar se conectar. Outros dispositivos funcionam bem. Eu tentei excluir a configuração e refazê-lo várias vezes, e isso não funciona.
Então, olhando para o syslog, parece que a requisição DHCP está expirando. Eu posso conectar-me à rede se eu definir manualmente o IP e outras configurações, mas ainda não tenho conexão com a Internet por meio do Wifi - acho que minha configuração manual ainda está um pouco desligada.
Aqui está o lspci:

Alguém tem alguma ideia?
Isso não é realmente uma resposta, é uma solução. Parece que, como já foi notado, o driver incluído no kernel em 13.10 está com defeito. Eu instalei a versão do kernel 3.8.13-03081312-generic do link e inicializei a partir dele. Meu wireless está funcionando bem agora.
Edit: O driver no kernel 3.9.11-030911-generic também funciona, e é isso que estou usando agora.
E ainda outra atualização: o Kernel 3.12.0-031200-generic corrigiu o problema.
Eu tive exatamente o mesmo problema e encontrei uma correção bastante artificial: remasterizar o live CD. Em uma instalação do Ubuntu eu instalei o Ubuntu Customization Kit (UCK) e usei para personalizar o ISO original do Kubuntu 13.10. Basicamente, o UCK chroots no ISO e permite que você o personalize. Eu comecei o UCK e pedi para me dar acesso a um console, então eu modifiquei o /etc/apt/sources.list e adicionei esta linha:
deb http://archive.ubuntu.com/ubuntu/ saucy-proposed main restricted universe multiverse
para permitir o download dos pacotes mais recentes (instáveis). Então eu corri apt-get update e apt-get dist-upgrade , que instalou, entre os outros, plasma-nm e outros pacotes relacionados à rede. Então terminei a sessão do UCK e construí um novo ISO. Se eu iniciar meu sistema usando este ISO personalizado, então o DHCP não expira e, aparentemente, tudo funciona bem.
Eu posso colocar meu ISO online se alguém estiver interessado (apenas deixe um comentário, eu não quero enviar 1GB se ninguém vai usá-lo), no entanto peço que você crie seu próprio ISO porque é simples e você não precisa confiar em mim e assumir que eu não adulterei o ISO.
Lembre-se de que testei apenas o sistema em tempo real e não executei uma instalação completa. YMMV.
Eu tive o mesmo problema ao instalar o 13.10 a partir de um ISO de construção diária. A atualização completa do sistema corrigiu o problema para mim.
Os passos que eu segui foram:
dhclient eth0 para configurá-lo e verifique se a interface está ativa apt-get update / apt-get dist-upgrade Isso resolveu o problema para mim. No entanto, de vez em quando, o Network Manager tentava assumir o controle e desconfigurar a conexão, fazendo com que o download parasse. Eu tive que cancelar o download, executar dhclient eth0 novamente e, em seguida, retomar o dist-upgrade.
Espero que funcione para você!
Existem alguns problemas com o driver incluído no 13.10. Parece estar ficando cada vez pior.
Se você se sentir aventureiro, peguei o código-fonte do driver e arrumei tudo para mim. Eu postei no Github: link
Até agora esta é a única versão do driver que eu conheço (além do pré-empacotado) que compila e trabalha no Ubuntu 13.10. Existem instruções de instalação no arquivo README.md .
Você pode tentar usar esse script que eu criei na rede:
Caso! [%] em .bin / sh nmcli nm sleep = false 'rede' Caso final
e pode funcionar bem assim.
