![]() Ive read that its needed to switch network card to promiscuous mode. The monitor mode Wi-Fi interface will be available to start capturing. Hello everyone, I need to use Wireshark to monitor mirrored traffic from switch. Next, click on the “Install integration” button to allow Wireshark 3 to interact with Acrylic Wi-Fi Sniffer. Promiscuous Mode should probably be allow, unless you have a network interface dedicated only to HA, which means not even the host OS can use it.

NDIS is a native Windows mechanism to turn a card into a Wi-Fi sniffer. When Acrylic Wi-Fi Sniffer cannot enable monitor mode on the installed WiFI card using its driver we can use NDIS driver, by installing it in the program control panel. ![]() WiFi cards available for use as a device sniffer ![]()
