34 Your driver has to support monitor-mode.
35 I am using an Atheros-based internal WiFi-card and an Alpha-USB-WiFi-device
36 with Realtek-Chip. The drivers I used a while ago needed a patch to work with
37 monitor-mode, but the recent drivers don't. Take a look at the driver-section
38 on the aircrack-ng homepage. Maybe your driver needs to be patched.
