I certainly have 2 wifi cards
Realtek 8188 wireless works at half the capacity of my internet/wifi signal, which I have inside my pc/rack and cannot extract from it.
My second/wifi card is a Linksys/WUSB54GC v3 wifi adapter. and it works wonders, it's more the green led / wifi is activated without problems and blinks in FreeBSD, this is very good for me since it takes the Ralink RT2670 controller or something like that and it's the one I always want to use.
Thanks for your time, I really appreciate it.
