Bug de dispositivo sem fio no 13.10. BCM4313 registra como eth1 em vez de wlan0 e sem acesso à internet

Question

Meu WiFi do hotel exige que eu faça login com um nome de usuário & amp; senha depois de se conectar ao hotspot. Então, meu navegador abriria uma página com o nome de usuário & amp; campos de senha para login e, em seguida, conectar-se à Internet.

Mas, infelizmente, o Firefox & amp; O cromo parece não funcionar. Não acho que seja relacionado ao navegador, mas uma configuração para o roteador ou driver WiFi que está criando esse problema.

Usando o driver sem fio Broadcom 801.11 STA (proprietário). Tentei código aberto também, mas mesmo resultado.

A imagem vinculada abaixo mostra minha configuração de conexão Wi-Fi & amp; Cromo A própria página de login aparece depois de muito tempo e depois de inserir as credenciais, ela continua carregando para sempre. É o mesmo para qualquer outro navegador. Então, eu não acho que seja um problema no navegador, mas algo relacionado à configuração de WiFi ou ao gerenciamento de rede.

Curiosamente, posso me conectar a redes WiFi usando o WPA sem qualquer problema. O hotspot ad hoc é um problema e essa é a minha rede doméstica normal. Espero conseguir ajuda para resolver este problema!

Eu tentei repetir o mesmo hotspot após o login do meu android, criando um repetidor virtual com a chave WPA e funciona. Eu posso navegar no Ubuntu usando esse método, mas não posso estar fazendo isso regularmente! Tentei carregar a mesma página de login do WiFi do hotel enquanto procurava meu repetidor WiFi criado no celular e anexava uma captura de tela abaixo. A página é carregada de maneira rápida e fácil. Isso significa que algo está errado com o modo como o gerenciador de rede lida com conectividade adhoc & amp; entrar?? Eu instalei o wicd0, mas ele falha na inicialização e não ajuda em nada!

ifconfig output é:

Eu me pergunto por que o wireless é configurado em eth1? Eu acho que este é um bug com versões anteriores do Ubuntu, mas isso é normal em 13.10 ou há uma configuração errada aqui?

O dispositivo sem fio no meu pc é BCM4313 e eu instalei o bcmwl-kernel-sources, ferramentas wireless para suportar o dispositivo. Eu também reinstalei o bcmwl-kernel como sugerido no site da broadcom, via gerenciador de pacotes synaptic.

Nada mudou essa situação!

Eu tentei inicializar em um LiveUSB e, em seguida, ifconfig resultados mostram o wireless em wlan0. Mas então o wireless conecta e carrega a página de login. Então, o problema com a configuração do dispositivo agora é?

Eu realmente quero consertar isso antes de começar a configurar as outras coisas, como gráficos da ATI e outras, no laptop, para superaquecimento. A falta de acesso à Internet é um erro muito ruim para mim. Qualquer ajuda é apreciada!

Answer 1

Atualmente, estou trabalhando em um laptop com a mesma placa de rede sem fio, que funciona bem. Então, vamos começar a cavar ...

Meu conselho é não usar o driver de propriedade STA, mas o brcmsmac de código aberto. Isso deve ser incluído nos kernels recentes.

Como você disse e, como posso ver na sua captura de tela, sua configuração de Wi-Fi está definida como Ad-hoc. Eu acredito que deveria ser instrumental.

Vamos comparar alguns resultados.

Qual kernel você está usando? Eu estou usando um kernel mainline, no entanto, ele tem trabalhado com o kernel do Ubuntu fora da caixa com 3.8, 3.10 e 3.11 também.

Se o driver brcmsmac estiver instalado corretamente, o lsmod deve fornecer isso.

No /etc/modprobe.d/blacklist.conf eu tenho um par de módulos broadcom na lista negra. Verifique se você tem essas listas negras também e, se não, tente o que acontece se você as adicionar e reiniciar.

# replaced by b43 and ssb.
blacklist bcm43xx

# Disable the recently enabled b43 module (kernel 3.11?) - manually added
blacklist b43

Não tenho pacotes bcmwl instalados.

arthur@AOD270:~$ dpkg -l | grep bcmwl
arthur@AOD270:~$ 

Meu resultado de ifconfig

arthur@AOD270:~$ ifconfig wlan0

          inet addr:192.168.1.51  Bcast:192.168.1.255  Mask:255.255.255.0

Espero que isso ajude você no caminho certo para encontrar a causa. Algum dos itens acima ajudou a resolver seu problema?

Estou assumindo que você está se referindo aos padrões 802.11 adhoc. Nesse caso, eles são mais lentos que os protocolos Wi-Fi normais. Deixe-me reformular isso. Eles são assustadoramente lentos. Eu estava pensando em montar uma rede Adhoc no bairro, mas foi horrível com os protocolos da Adhoc. A melhor rede adhoc que você pode configurar seria WDS com o protocolo OLSR.
