What is Wi-Fi probe request?

Probe requests advertise the mobile stations supported data rates and 802.11 capabilities such as 802.11n. If they have compatible data rates, a probe response is sent advertising the SSID (wireless network name), supported data rates, encryption types if required, and other 802.11 capabilities of the AP.

What is Wi-Fi probing?

User devices that have a WiFi interface periodically perform a wireless probe procedure by actively sending a control frame, known as a ”probe request”. The purpose of this procedure is to have nearby wireless access points send information about wireless networks that are available for connection.

4. Analyze sketchy activity.
5. Use network monitoring software.
6. Check your router’s log.
7. Keep Wireshark running.
