Ayuda con aircrack-ng

donfirefox

Tengo el siguiente problema:

Al ejecutar airmon-ng no me arroja donde esta establecido el monitor, creo que puede ser problemas con mi tarjeta inalambrica, les dejo la siguientes capturas.

root@goku:/home/ricardo# airmon-ng start eth1


Found 5 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!
