We can use the iwconfig command to change the channel. That's because we're listening on one WLAN channel only.

Now, if you execute this, you will notice not all nearby networks are available.

#Wifi scanner program code#
To the main code now: if _name_ = "_main_": Since we're going to use sniff() function (which blocks and start sniffing in the main thread), we need to use a separate thread to print the content of networks dataframe, the below code does that: def print_all(): Now we need a way to visualize this dataframe. In hidden networks, the access point leaves the info field blank to hide the discovery of the network name, you will still find them using this tutorial's script, but without a network name. You will encounter some networks that don't have the SSID ( ssid equals to ""), this is an indicator that it's a hidden network. Finally, we add these information to the dataframe with the BSSID as the index. Scapy's Dot11Beacon class has the awesome network_stats() function that extracts some useful information from the network, such as the channel, rates, and encryption type. This callback makes sure that the sniffed packet has a beacon layer on it, if it is the case, then it will extract the BSSID, SSID (name of access point), signal, and some stats.

Now the code of this tutorial won't work if you do not enable monitor mode in your network interface, please install aircrack-ng (comes pre-installed on Kali) and run the following command: Note: This tutorial assumes you are using any Unix-based environment, it is also suggested you use Kali Linux.Īfter that, we gonna use pandas just for printing in a nice format (you can change that obviously): pip3 install pandas

Or you can clone the current development version in Github: git clone To get started, you need to install Scapy, I have cloned the development version, you can also install it using pip: pip3 install scapy Related: How to Extract Saved WiFi Passwords in Python.

If you're in this field for a while, you might have seen the airodump-ng utility that sniffs, captures, and decodes 802.11 frames to display nearby wireless networks in a nice format, in this tutorial, we will do a similar one. Have you ever wanted to build a tool to display nearby wireless networks along with their MAC address and some other useful information? Well, in this tutorial, we are going to build a Wi-Fi scanner using the Scapy library in Python.
