Buenas, prometo que he leído y releído muchos hilos pero no consigo dar con la tecla de mi problema. He visto que tiene mucho recorrido y que sigue vivo en algunos foros todavía. En otros dan soluciones (como un hub usb 2.0 pasivo) que he probado y no he conseguido resolver.
Básicamente el problema es que el dispositivo usb se desconecta aleatoriamente del router y tengo que reiniciar servicio network (tengo una watchdog en el servicio crontab para que reinicie el servicio network si la interfaz wwan pierde salida exterior). Desgraciadamente esta tarea está saltando varias veces al día.
Quiero señalar que mi problema no es falta de detección del dispositivo ni de rendimiento. Ambos aspectos funcionan muy bien con la información que he podido leer en los foros. Es el problema de la desconexión lo que no he conseguido solucionar.
Vamos al lío:
* Router HG556a BZRB (ralink)
* ALFA AWUS036NHA (AR9271)
* He probado varios firmware de AA,el último firmware que he instalado es: openwrt- HG556a_usbATH-pllfix-SLUB compilado por danitool
