Hi everyone.

my laptop wireless card is : intel wifi 5100 and detected automatically.

2: airodump-ng --encrypt wep mon0

3: airodump -c 1 -w alireza -bssid [bssid adsl modem] mon0

4: aireplay-ng -1 0 -a F4:3E:61:20:F7:E8 mon0
No source MAC (-h) specified. Using the device MAC (00:16:EA:AB:99A)
14:05:13 Waiting for beacon frame (BSSID: F4:3E:61:20:F7:E8) on channel 8
14:05:13 mon0 is on channel 8, but the AP uses channel 1

even with MAC address... but:
