Double-click the
Network Stumbler
icon on the desktop.
The NetStumbler application will start.
The left side of the application lists the categories and filters.
The right side of the screen lists the specifics.
*Note:
It is important to understand at this point that NetStumbler will only work
with specific network cards and VMware Workstation may require you to set
your network card to Network Address Translation (NAT) instead of the
bridged setting in order for VMware Workstation to identify your wireless
card. As it appears my VMware Workstation-compatible wireless card has
been misplaced, the remainder of this lab was conducted from the host
computer and not the VMware Workstation machine. The results are identical.
