Tengo un nuevo HP Stream 11-r001nd. Puedo conectarme a mi red, pero es demasiado lento. Incluso cuando pongo mi computadora portátil y el enrutador uno al lado del otro, es demasiado lento para ver un video de YouTube (si es que la página web de YouTube se carga). En Windows 10 este problema no existía.
En este video de youtube se muestra que usando la versión 14.10 la velocidad era aceptable. Pero esa versión ya no es compatible.

Relacionado:¿No puedo encontrar los paquetes sstp VPN con Ubuntu 16.04 LTS?Sin embargo, su problema real parece ser que la tarjeta Realtek Wifi RTL8723be no funciona correctamente. Siga los pasos dados en la solución allí.
Si esto resuelve su problema, haga clic en la marca de verificación a la izquierda para mostrar que su problema está resuelto. Si no, vuelva a publicar la salida del script wifi, preferiblemente después de resolver los otros dos errores. El primero debería desaparecer después de un reinicio. El segundo no aparecerá si retira el dispositivo USB antes de ejecutar el script.
Revisé los resultados de su segunda ejecución del script inalámbrico. Veamos algunos fragmentos:

Esto muestra que el atasco proviene de un punto de acceso llamado serie HP-print-C3-Deskjet 2540. Sugeriría cambiar el canal de RF del punto de acceso o de la impresora para que estén en diferentes canales. En este momento, ambos están en el canal 1. Los únicos otros canales que se usan son el 6 y el 7, por lo que tiene mucho para elegir.
La impresora está actuando como un punto de acceso porque ha presionado el botón directo inalámbrico (consulte la página 53 del manual del usuario). Debería haber conectado su impresora a su enrutador siguiendo las instrucciones en la página 49 del manual. El manual de usuario está disponible en línea aquí
