I recently bought an ALFA-AWUS03NHA Wireless Card, I am running Debian and I want to use the card with the aircrack-ng suite of tools. However, I am pretty sure it is using my laptops wireless card, for a few reasons: the light on the ALFA card never flashes, and if I'm running a command and unplug the card it makes no difference.I've done some research into the drivers for the card, I believe it uses the AR9271 driver, which is included in some download called 'ath_9k'. But I think this is already installed, at least when I run lsmod the drivers show up:Before plugging in the card, I run the following commands:~$ sudo iwconfig[sudo] password for root: eth0      no wireless extensions.lo        no wireless extensions.wlan0     IEEE 802.11bgn  ESSID:...

After plugging the card in, there still seems to be one accessible wireless interface, wlan0. What is supposed to happen, do I get a new interface, wlan1, on top of the old one, or should the wireless card overwrite the other and become the new wlan0?If I run the same lsmod command as before now the card is plugged in, I get new drivers appearing in the 'usbcore' section:~$ lsmod | grep athath9k_htc              64602  0 ath9k                  98430  0 ath9k_common           12634  2 ath9k,ath9k_htcath9k_hw              391009  3 ath9k_common,ath9k,ath9k_htcath                    26026  4 ath9k_common,ath9k,ath9k_htc,ath9k_hwmac80211              488308  2 ath9k,ath9k_htccfg80211              436618  4 ath,ath9k,mac80211,ath9k_htcusbcore               166472  5 uvcvideo,ehci_hcd,ehci_pci,usbhid,ath9k_htcI'm pretty sure neither of those things are happening, instead the wireless card simply isn't being used, I'm sure of this as I can unplug it with no effect, and it never flashes at any point during set up or execution of commands.So, the question!Do I have the correct drivers installed for the card? If so, why is it not working? Every video or tutorial I've seen assumes the Alfa is just plug and  play. Am I missing out some step here?Thanks!
