How to activate Router/Ap in Win7 64bit?



Hi, i have a usb-pen Alfa’s brand installed in my notebook and a secondary integrated wifi card.
For about 4 days i’m trying to install router/Ap feature but I
cannot do it.
It seem like is a difficult feature to work.
I tried Virtual Router that crashs, Connectify and internal router
feature in my app/driver of my Alfa’s device. I have always
problems…each setting with external programs modifies settings
in internal Virtual router.
Can you suggest me a right way by cleaned system to enable
definitively this working feature?
