iw_parse

Parse the output of iwlist scan to get the name, address, quality, channel, and encryption type of all networks broadcasting within your Wireless NIC's reach.

Dependencies

pip - If you don't have pip installed, followed the link.

Installation

pip install iw_parse

Usage

iwlist <INTERFACE_NAME> scan | iw_parse

Replace <INTERFACE_NAME> with the system name for your wireless NIC. It is usually something like wlan0. The command iwconfig will list all of your network interfaces.

Example:

iwlist wlan0 scan | iw_parse

The result should look something like:

Name             Address             Quality   Channel   Encryption
wireless1        20:AA:4B:34:2C:F5   100 %     11        WEP
wireless2        00:26:F2:1E:FC:03    84 %     1         WPA v.1
wireless3        00:1D:D3:6A:3C:60    66 %     6         WEP
wireless4        20:10:7A:E5:02:98    64 %     1         WEP
wireless5        CC:A4:62:B7:D2:B0    54 %     8         WPA v.1
wireless6        30:46:9A:53:3C:76    47 %     11        WPA v.1
wireless7        A0:21:B7:5F:84:B0    44 %     11        WEP
wireless8        04:A1:51:18:E8:E0    41 %     6         WPA v.1

Example from Python shell:

>>> import iw_parse
>>> networks = iw_parse.get_interfaces(interface='wlan0')
>>> print networks
