How can airodump determine if packet capturing is successful?

To determine if Airodump-ng has successfully captured packets, you can observe the following indicators:

1. BSSID (MAC address of the wireless access point): In the Airodump-ng output, make sure to check if the BSSID is listed. If it is not, it could be due to improper configuration of the wireless card or it not being connected to the wireless network.
2. PWR (Signal Strength): Monitor the PWR column, which displays the received signal strength. A negative PWR value indicates a weak signal, while a positive value indicates a strong signal. A higher PWR value indicates better signal strength, making it easier to capture data packets.
3. #Data Packets: Look at the #Data column, which displays the number of packets captured. If the number of packets keeps increasing, it indicates that packets have been successfully captured.
4. Channel (CH): Ensure that the wireless network card and the target network are on the same channel. If they are not matched, it may be unable to capture data packets from the target network.
5. ESSID (Wireless Network Name): In the Airodump-ng output, check if the ESSID of the target wireless network is listed. If the ESSID is not listed, it could be due to the wireless card not being properly configured or not connected to the wireless network.

In conclusion, by observing indicators such as BSSID, PWR, #Data, CH, and ESSID, we can determine if Airodump-ng has successfully captured packets.
