Olá amigos do FórumDebian,

Boa noite a todos!!!

Estou aqui postando meu problema com wpa_supplicant para se conectar em um acess point.

vamos ao problema...


- PROBLEMA: TENHO UMA PLACA DE REDE WIRELESS ATHEROS COM O DRIVER ATH9K CARREGADO E PLACA JÁ ESTÁ RECONHECIDA E TRABALHANDO, PORÉM ELA SÓ SE CONECTA AO ACESS POINTR VIA KNETWORK-MANAGER, QUANDO TENTO CONECTAR VIA WPA_SUPPLICANT DÁ ERRO E FICA EM LOOP INFINITO. LOGO ABAIXO MOSTRO COMO PROCEDI:

- O QUE FOI FEITO: gerei o arquivo de configuração wpa_supplicant.conf e coloquei o ssid dentro do arquivo junto com a chave Pré-compartilhada.

# /etc/wpa_supplicant/wpa_supplicant.conf

# wpa_passphrase ssid minhapassprase > /etc/wpa_supplicant/wpa_supplicant.conf

#### Após feito tudo isso rodei o comando wpa_supplicant com seus paramentros. #######

wpa_supplicat -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -d -D wext

OBS: a saida deste comando foi esse loop, que mostrou que chegou a se autenticou com sucesso porém não estabelece a conexão e fica em loop, saida do comando abaixo:

- NOTA: JÁ TENTEI ME CONECTAR PARANDO O NETWORK-MANAGER, MAS NÃO DEU CERTO, CONTINUOU DA MESMA FORMA, OLHA LÁ EM CIMA DESTACADO A AUTENTICAÇÃO FEITA.

######### E quando uso outro driver no comando, ( o driver que está controlando a placa de rede wireless ele dá essa saida ai o:

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -d -D ath9k
Initializing interface 'wlan0' conf '/etc/wpa_supplicant/wpa_supplicant.conf' driver 'ath9k' ctrl_interface 'N/A' bridge 'N/A'
Unsupported driver 'ath9k'.

Aguardo uma solução postada por alguns dos amigos do fórum, pois preciso mesmo de uma solução.

obrigado mais uma vez ao Fórum Debian pelo espaço reservado.

aqui eu usei a net a cabo para editar ai sources.list e add repsitórios e instalar o wicd,com ele instalado antes de tudo editei assim:

configurando rede cabo e Wireless

editar /etc/network/interfaces

#gedit /etc/network/interfaces
OBS: sempre execute o ifconfg para saber a interface ok?

adicionar:
#REDE CABO
iface eth0 inet dhcp
#wireless
iface wlan0 inet dhcp

depois instalar o wicd
marcar o daemon meu usuário [*]
no Wicd
ABA PREFERENCES=> External Programs setado em dhclient e não a opção Autmatic (Recommended)

reboot o PC e já vai aparecer as redes wireless,tenho a mesma placa de rede sua.num acer 5551

Olá colegas do fórum do debian.

Problema Resolvido.....

Resolução: só tive que desativar o network-manager, ativar o wpa_supplicant e configurar a rede para a interface wireless, no meu caso "wlan0".

Obrigado ghost pela ajuda, agradeço o fórum do debian pelo espaço.

Belo tópico. Estava com o mesmo problema e nao sabia como resolver.Ele ele me ajudou muito. Valeu por me ajudarem.

Boa tarde,

Por favor mudar o adicionar ao tópico a palavra [RESOLVIDO], desta forma evitamos visitas desnecessárias ao mesmo, e aumentamos nossa base de problemas resolvidos.

Até mais...
