Duplicate ARP responses from Intel Wi-Fi 6E AX211 on Windows 11
I have noticed duplicate ARP responses from an Intel Wi-Fi 6E AX211 on Windows 11 64-bit when the system is sleeping. The test system has MAC address 08:9d:f4:29:34:16 and IPv4 address 192.168.1.192. The number of duplicates varies between a few and several hundred.
This example shows four consecutive arp-scan runs, using grep to display only the reponses from the test system:
rsh@bookworm:~$ arp-scan -l | grep 192.168.1.192
