WiFi & Privacy treats what NetworkManager can do
summary
Monitor-mode Wireshark capture shows ~45,000 frames over 10 minutes with roughly 10% probe requests, including one station repeatedly probing a single SSID that makes it trackable. NetworkManager already randomizes MACs for scans and lets you choose association behavior (preserve, permanent, stable randomized per connection) via cloned-mac; change with nmcli connection modify <name> cloned-mac <value>. DHCP identifiers leak persistent IDs (IPv4 client-id, IPv6 DUID/IAID) but NetworkManager can set them to MAC-based or custom values and can drop the DHCP hostname option to reduce identifiability.
