Hola a todos: Tengo un problema con la conexi�n PPP que, despues de leer los HOWTO y probar de todo, no he conseguido resolver. A ver si hay alg�n gur� que pueda ayudarme.
El problema es que la conexi�n se bloquea y, tras un rato, se muere, pero s�lo cuando estoy transmitiendo datos, bien por ftp o bien por correo electr�nico. La cantidad que puedo transmitir es variable, a veces aguanta archivos de mas de 100kb, pero lo habitual es que se bloquee a partir de los 10kb. Los archivos peque�os llegan sin problema. Cuando est� bloqueada, ni siquiera puedo hacer 'ping': no me responde nada, ni la red es inreachable, ni nada, se queda esperando qu� se yo. La recepci�n funciona bien, con una velocidad m�xima de algo menos de 4k/s (no s� si es un poco poco) y creo que no se ha cortado nunca. Al conectarme, tampoco tengo demasiados problemas; a veces hay que hacer dos o tres intentos para que el modem se decida a marcar, pero al final funciona. Esto me ocurre con tres servidores diferentes: Jazzfree, EresMas y el Servidor de la Polit�cnica de Madrid. La configuraci�n del PPP se la he dejado a PPPConfig, pero tambi�n he intentado hacerla a mano, variando opciones de /etc/ppp/options sin �xito. Tengo instalado Potato, con el kernel "default" tal como ven�a en la distribuci�n (sin recompilar) El ordenador es un Portatil Celeron 433Mhz de AHTEC y el modem, una PCMCIA OVISLINK Fax Modem 56K V.90.
