awus036H original from alfa was broken since i used 3 commands in mdk on a AP in full power .
Sorry, that is NOT possible.
It is NOT possible to damage a wifi interface exposing it to an AP in full power (all APs are by default set to full power), or simply running any of the mdk tests.
I suggest you to check it better, maybe using different PC/antenna/usb cable, it might be working thou.
If you really damaged your wifi interface, you probably did something more serious, such as: patched the drivers with the mod to push transceiver power over limit, fiscally hard hit the device, short-circuit some pin in the USB port, plugged some rusty-faulty antenna, and so on.
