Si quieres potencia y no te importa que el precio sea algo elevado, la Alfa.
Si quieres que sea mas barata, la edimax.
salu2
-
No tengo la edimax, pero hablan muy bien de ella.
Tengo la alfa y es una pasada. En ebay te sale por unos 50 euros.
-
Yo confirmo que la edimax va de lujo.
De la alfa lo que te digan mis compañeros, aun no tenio la suerte de probarla.
Saludos

Pues la decision no es complicada, y la comparacion es ........ dificil .....
¿que prefieres?
Alta potencia o potencia normal?
Por que una es de alta potencia y la otra es normal y corriente ......
Como a dicho gscabi
Si quieres potencia y no te importa que el precio sea algo elevado, la Alfa.
Si quieres que sea mas barata, la edimax.
Eso es lo que tienes que valorar, las dos son muy buenas

entonces me decidire x la alfa,creo que me sale por unos casi 60 euros con gastos de envio
