netsh is a command-line utility to configure a Windows machine from the command-line. Here I'm going to show the commands to get information about the wireless interface.

The Base Query Command

The command takes the form:

netsh wlan show <what>

The Whats

all:

netsh wlan show all

Shows all the available information concatenated together.
drivers:

netsh wlan show drivers

Shows driver information for the interface.
interface:

netsh wlan show interface

Shows the interface information. Sample output:

There is 1 interface on the system:

    Name                   : Wireless Network Connection
    Description            : Intel(R) Centrino(R) Wireless-N 100

    State                  : connected
    SSID                   : allionstaff

    Signal                 : 99%
    Profile                : allionstaff

    Hosted network status  : Not started

Getting The IP Address

To get the IP address you need to use a different subset (not wlan):

netsh interface ipv4 show addresses

Sample output:
