tengo la misma tarjeta y hp tambien, y me inyecta desde bt4. mo he probado wifislax ni wifiway.
al ponerla en modo monitor te crea una "mon0" y es esa con la que tienes que inyectar. he de decir que no me inyecta a topos los aps probados. solo lo he probado en mi red, con varios routeres y me ha funcionado. ¿sera por la cercania?
mira esto a ver si te ayuda:
bt ~ $ sudo airmon-ng start wlan0
Found 2 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
