When u made the post i was compiling the kernel so i dind't use the drivers from entropy, I use the drivers I already had.
At start I was following this configs http://wireless.kernel.org/en/users/Drivers/ath9k_htc(I used make menuconf) for atheros chip and I saw a line for rtl chip and activate it, I think that the kernel wasn't loading wtv is load(drivers or I dunno what it loads).
