deteccion de redes y conexion wifi en lubuntu

muy buenas.soy de las personas q migro de win xp,y me pase a lubuntu 14.04 lts.todo desconocido para mi,pero google me ha ayudado mucho,aunque hay algo q no he podido solucionar.
les cuento,ojala se entienda.en el icono de conexiones q esta en la barra de tareas solo me muestra una sola red disponible,q no es la mia.añadi a mano el ssid q me corresponde,y sale como conectado al 100% la señal,pero no puedo conectarme a internet,ni descargar actualizaciones ni nada.es como si no estuviera conectado.me explico?
mi pc es un olidata L41II1,y la tarjeta de red al parecer es ralink rt73.ejecutando en la terminal comandos no me aparece esta,solo el ethernet,y en controladores adicionales no me sale nada para descargar.
aqui la info q recopiló system profiler and benchmark:

he aqui la informacion completa del sistema.no les escribo que he hecho para solucionar el problema,ya q perdi la cuenta de comandos ingresados al terminal,y quisiera empezar desde cero.
atento a sus comentarios.

Si te sale como conectado has probado hacer un ping a algun lugar para ver que responde?

ping google.com
ping 8.8.8.8

gracias por contestar.voy a probar lo q dices a ver q pasa,y posteo novedades.igual tengo otro pc aca con el q no tengo ese problema,todo bien con ese,es mas moderno claro,y me detecta todas las redes del area sin problema.al conectarme a la mia me sale con un maximo de 50% de intensidad de señal,andando impecable,por lo cual es raro q este me diga q la señal esta al 100%...
voy y vuelvo con novedades

edito.- volvi,y mira lo q es la tontera.anoche se chingo el internet,o mas bien dicho,funcionaba bn con el modem 3g q tengo y de repente se hecho a perder de la nada esto y bloqueo todas las redes.salia todo en gris en el applet.no entendi q fue lo q paso,no estaba haciendo nada extraño,ni descargando ni visitando paginas desconocidas....me aburri y apague el pc.
hoy al prenderlo me salio el aviso de "lo sentimos,ha ocurrido un error inesperado..." ,el primer error desde q lo instale.
de costumbre,puse mi modem 3g y a navegar...y voy a hacer eso q me dices tu,desconecte el modem y voy a ver las redes wifi y ahora de la nada me esta detectando bn las redes disponibles del area,y ya me funciona la conexion a mi red,jajaja.2 semanas batallando con esto y de la nada se soluciono.que cosas.no alcance a hacer lo que me dijiste.
muchas gracias tux por tu ayuda igualmente,se agradece el tiempo q se toman en moderar,contestar.

weee,la luna de miel duro menos q un dulce.apague el pc y todo vuelta a lo mismo.yo de informatica nose nada,dejame averiguar como se hace el ping y vuelvo.
