The first image shows Wireshark's interface-selection screen and my router's two interfaces. The following two screenshots were taken directly from Wireshark in full-screen mode on my WiFi-to-WiFi router - which was running on my Raspberry Pi 4 with the 64-bit beta version of Raspberry Pi OS. That cleared out all extraneous data traffic unrelated to what I was about to do.ġ0: On my iPhone's Safari web browser, I quickly tapped a shortcut to BBC News at Īnd that was that - I sat back and watched all the network traffic flowing in and out of my iPhone - a crazy range of activity triggered by visiting just one website!

It's what my iPhone was connected to.ĩ: I then clicked the green shark fin button in the upper-left corner - 'Restart current capture'. It then correctly showed the two WiFi interfaces that my router creates - OBwlan0 (the Raspberry's on-board WiFi chip) and DGwlan1 (the USB WiFi dongle).Ĩ: I then double-clicked OBwlan0 - because that's my router's Access Point. I clicked the drop-down box on the right-hand side and unchecked all the boxes except 'Wireless'.

It said 'Should non-superusers be able to capture packets?' I accepted the default option and said NO by tapping the Enter key.Ħ: To launch Wireshark, I simply ran sudo wiresharkħ: An interface-selection screen then appeared.

I began by doing exactly what you see in my infographic at the beginning of my tutorial:ġ: Activated my iPad's mobile hotspot (Apple calls it a “Personal Hotspot”).Ģ: Activated my Raspberry-based router (the toggle switch on the desktop said 'Router is On').ģ: Connected my iPhone to my router's Access Point.Ĥ: Installed Wireshark by running sudo apt install wireshark in Terminal.ĥ: During the package installation, a configuration screen automatically appeared. Wireshark allows me to detect and analyze all the data packets travelling through my router - and any device(s) connected to it. As a fun test for no particular reason, I ran the Wireshark network traffic analyzer on my WiFi-to-WiFi router.
