If there are packets captured, Congratulations, your hardware should be fine!Īctual Wi-Fi Packet Capture (using Omnipeek)įor doing something meaningful on this, we can use this setup to capture actual Wi-Fi activities/packets of our target device and extract some useful Wi-Fi info.Now that you have set up Wi-Fi dongle correctly, you can try capturing Wi-Fi packets RIGHT AWAY.
