I have another problem almost related to the one you are having. I have this alfa that i bought recently cause i cannot get a wifi signal on my room though we do have a wifi on our building. But then after i installed everything it cannot find the wifi on our building even you are infront of the acces point still it will not detect. I wonder what seems to be the problem cause it can connect and detect to another wifi outside our building but the nearby it cannot. if anyone has some suggestion or can give me reason why alfa cannot detect the nearby signal please email me or reply to this.
