ACX100 Wireless

["Luiz Henrique" <quick@process.com.br>]

Alguem ja instalau a placa D-link 520 + seguinte o as instruções do site do Emota.

 

A Minha Placa  funcionou  mas estou com uma duvida o meu provedor me passou
somente o SSID e disse que nao precisa do restante mas a placa nao conecta
nada.
Entao se o meu provedor so me passou o SSID e o ÌP eo Gateway, e no windows
esta funcionado. No script start_net ficaria como ou tem outra forma de fazer isso

segue abaixo o script start_net  de inicialização da placa como exemplo:

#!/bin/bash
