Can you use Wireshark on public WiFi?
Yes. Wireshark can capture packets off of a WiFi network as long as the computer it is installed on has a WiFi transceiver and is in promiscuous mode. Wireshark uses the Airpcap standard for wireless packet capture.
Can Wireshark sniff WiFi?
Wireshark (formally Ethereal) is freely-available software that interfaces with an 802.11 client card and passively captures (“sniffs”) 802.11 packets being transmitted within a wireless LAN.
Can public WiFi be monitored?
Because it does not require authentication, a public WiFi Internet connection means hackers might be able to see your data. Not only that, but the Wi Fi router's administrator might see what sites you use and could sell your data. Therefore, do not visit websites with sensitive information if you're on public Wi-Fi.
