Alfa 036 - sees beacons for one network, but internal wifi sees all networks beacons

[sandaili]

I have BT4 installed on a laptop. The laptop has an internal wifi (ra0), but I am using the Alfa awus036H for testing.

My Alfa does not see any beacons except for my test wep, which I have cracked. But I thought today when playing around getting ready to test WPA, that it sees only my beacons, and not any other networks. I must have a setting wrong?

So I put down the card using the following:

ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

Then I started airodump-ng mon0, which shows all the networks, but still only shows beacons for my router.

However, when I enable the ra0, it shows beacons for all networks, not just mine.

Does anyone know what I can do to fix this? I am a newbie, but trying to learn.

Hmmm,
I use the Alfa with no problems on a laptop with built in wifi - try:
ifconfig wlan0 down
airmon-ng start wlan0
airodump-ng wlan0
