BT5R2 x64 KDE installed on laptop.

My laptop's built in wireless card shows as 15dBm.

I just bought an Alfa AWUS051NH with 9dBi antenna rated at 30dBm (after the iw reg set BO trick)

However when I do back to back airodump's the signal strengths are pretty much identical between them?

To make sure I did this right I checked nearby netwworks with the Alfa unplugged, rebooted and then checked with the Alfa interface.

Is something wrong here or am I missing something?
