How to Purchase CommView for WiFi

Using CommView for WiFi in a Virtual Machine

You can install and use CommView for WiFi inside a virtualized Windows OS running as a guest operating system on a Mac (or PC, if you prefer a virtual environment for whatever reason). In order to do that, you will need virtualization software, such as VMWare, Parallels Desktop for Mac, or Virtual Box.

Guest Operating System

As a guest Windows version, you can use Windows 10, 8,1, 8, or 7, although we recommend Windows 10, 8.1, or 8 for the reasons explained below.

Hardware

To use CommView for WiFi for passive surveys, you need a compatible adapter. When you run our software on a Windows notebook, you can use any of the compatible adapters in different form factors. The list of compatible adapters can be found here. When you run CommView for WiFi inside a virtual Windows machine, you can use USB adapters only. Please refer to the adapter list to find the USB adapter you are going to use. We strongly recommend that you choose an adapter marked "Recommended." They are also always available from us directly when you buy the boxed version.

Virtualization Software Configuration

If your virtualization software supports USB 3.0 emulation (which is the case if you are using VMWare or Parallels Desktop for Mac), be sure to use USB 3.0 emulation rather than USB 2.0 emulation, even if the USB port and the Wi-Fi adapter you are going to use are USB 2.0. Support for USB 3.0 requires at least Windows 8 as the guest OS. USB configuration in VMWare is illustrated below.

USB 3.0 emulation is preferable because it dramatically increases the communication speed between the Wi-Fi adapter and guest OS. For example, in some adapters, switching the Wi-Fi channel might take 500 or even 1,000 milliseconds if you use USB 2.0 emulation and only 100 milliseconds if you use USB 3.0 emulation. Considering the fact that CommView for WiFi might switch channels every 250 milliseconds, this difference is dramatic. Using USB 2.0 emulation might slow down the application considerably.

For this reason, we recommend that you do not use VirtualBox as virtualization software. At the time of writing, VirtualBox has no USB 3.0 support. If you still want to use VirtualBox, at least use the Enable USB 2.0 (EHCI) Controller option; otherwise, your USB Wi-Fi adapter might not work.

Adapter Installation

Plug in the USB adapter into your computer. Once the adapter is plugged in, you will need to configure your virtualization software to use the detected USB device, i.e. disconnect it from the host OS and connect it to the guest OS.  The configuration method depends on the specific virtualization software that you use; please refer to the related documentation. After the virtual machine takes control of the adapter, Windows will notify you that a new USB device has been found and will try to find the driver for the device. Click Help => Driver Installation Guide in CommView for WiFi to find the instructions for installing our special packet capture driver. Once that driver has been installed, you can restart the application and use it.
