Ubuntu 14.04 wifi Realtek RTL-8100/8101L/8139

[edjin]

Olá pessoal, instalei em meu computador o ubuntu 14.04, e tenho um conector wifi "Realtek RTL-8100/8101L/8139 " na embalagem é especificado 802.11N, e nele acompanha um cd para instalação (o arquivo compactado "DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2" e instruções para compilação do mesmo...) segui a cartilha sudo make... porem o modulo não compilou. Existe alguma maneira de conecta-lo?

resultado do comando lspci:

Vejo que a maquina reconhece o conector de wifi, porem acredito que não faz nenhum modulo carregar...

Como poderia funciona-lo?

Boa noite!!

Os módulos estão ai, só não levantou.... o que tem dentro de:

/etc/modules

O módulo ta na blacklist? Se tiver, colocar um comentário#, salva e reinicia. #8139

vi /etc/modprobe.d/blacklist.conf

[edjin]

Obrigado amigo Andre Magrego, estarei testando esse procedimento e retorno com os resultados obtidos. Abraço.

Bom dia pessoal, olhei na lista negra em /etc/modprobe.d/blacklist.conf... mas não existe nenhum de mesmo nome, veja o arquivo:

O que vcs acham, o que posso fazer agora?
No aguardo amigos... Abraço.

Bem, já tenho a confirmação do que estava pensando: o que você deve fazer agora é... parar, e revisar seu procedimento, pq vc está errado desde o início.

1. O adaptador RTL-8100/8101L/8139 não é um adaptador WiFi, e sim cabeado.

2. Sua máquina não tem adaptador WiFi detectável.

3. Você baixou um script da internet. Muito, muito cuidado com qualquer coisa que você baixe pra sua máquina que não venha dos repositórios do Ubuntu.

o que posso fazer... qual o procedimento?

[zekkerj]

Primeiro vc tem que conseguir um adaptador wireless de verdade. Uma boa dica: eles costumam ter uma antena, não um conector RJ45 para receber um cabo.

esse é o que estou usando (ainda não)

[zekkerj]

Como eu disse, não há nenhum sinal de adaptador wireless em sua máquina.

[edjin]

Isso vc me disse antes... o que vc me indica fazer agora, instalar o ubuntu 13.10 (que funciona) ?  Trocar de adaptador nem rola, porque to longe de onde comprei. Vou ter que especializar em redes ? rsrsrsrs

Vamos estudando o caso, quem sabe nos resolvemos...
No aguardo...

Downgrade pra versão não-LTS? Nunca.

Seu adaptador wireless é USB, certo? É este aqui? "Bus 001 Device 020: ID 148f:7601 Ralink Technology, Corp. "

Se for, uma busca na internet pelo código "148f:7601" pode te dar algum resultado.
