Tras actualizar mi Samsung Galaxy GT-9003 a la \u00faltima versi\u00f3n disponible (2.3.5), he visto que he perdido algunas funcionalidades…… al conectarlo a mis port\u00e1tiles con linux (varios), por USB, no lo puedo volver a usar como modem… \ud83d\ude41 usarlo como AP wifi no me gusta, consume mucha bater\u00ed\u00ada.
\nVamos a comprobar…. ponemos el tel\u00e9fono en modo depuraci\u00f3n y lo conectamos a nuestro ubuntu….. hacemos un sudo dmesg<\/em> y vemos algo positivo… \ud83d\ude42
\n

\n<\/code>
\nVemos que se crea un nuevo modem USB \ud83d\ude42 en el puerto ttyACM0: USB ACM device<\/strong>…. y ahora vamos a investigar c\u00f3mo….
\nLo primero que se me ocurre es usar el viejo wvdial…
\n
\nsudo apt-get install wvdial
\n<\/code>
\nTras unos instantes tendremos instalados los paquetes… ahora hacemos la config…
\n
\nsudo wvdialconf
\n<\/code>
\nY ahora vemos la config… en mi caso tengo Joigo; el modem en el puerto ACM0. Editamos el fichero \/etc\/wvdial.conf<\/strong> y deber\u00e1 estar m\u00e1s o menos como este:
\n
\n[Dialer Defaults]
\nInit1 = ATZ
\nInit2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
\nInit3 = AT+CGDCONT=1,\"IP\",\"internet\"
\nModem = \/dev\/ttyACM0
\nPhone = *99***1#
\nIdle Seconds = 3000
\nAuto DNS = 1
\nPassword = internet
\nModem Type = USB Modem
\nStupid Mode = 1
\nCompuserve = 0
\nBaud = 460800
\nNew PPPD = yes
\nDial Command = ATDT
\nAsk Password = 0
\nISDN = 0
\nUsername = internet
\n<\/code>
\nYa tenemos listo el marcado y el modem… ahora para usarlo… desde el terminal, hacemos:
\n
\nsudo wvdial
\n<\/code>
\ny tendremos que ver en la consola, algo como esto:
\n
\ncraem@cepheusMAC:\/etc$ sudo wvdial

\nY voil\u00e1!!!! ya tenemos conexi\u00f3n a internet… nuestro flamante tel\u00e9fono android 2.3.x + linux ubuntu \/ debian \ud83d\ude42 problema solucionado.
\nAhora podemos ver si hay IP; hacemos un ifconfig y vemos el interface ppp
