Wimonitor is a wonderful product from Hacker Arsenal that saves pentesters the hassle of having to configure VMs, carry compatible wireless cards that support monitor mode etc. and comes with a web interface to do the configurations. It gives you the flexibility to plug in the device into the Ethernet port and start Wi-Fi monitoring on any OS. Basically it is a tp-link TL-MR3020 router with a custom firmware that does all the monitoring part and sends the packets to the host laptop (or Mac !) where you can start Wireshark and concentrate on the packet analysis.
I haven’t got one yet, but have been hearing good reviews about the product since launch. The shipping cost to EU is a bummer :(. Hopefully they will start shipping from EU soon.
Meanwhile - why not try this on a Raspberry Pi ?↪
