I have tried it again this few days but I still cannot capture the WPA handshake.
The reply from the system is as follow:

Sending 64 directed DeAuth. STMAC: [00:16:EA:C8:27:30] [0| 0 ACKs]

What have I done wrong?

I try to patch the new driver into the Wireless adaptor but it just gives me error: "drivers/net/wireless/zd1211rw/zd_mac.c", No such file or directory...
Please help...
