Is there a tool like wifi analyzer for ubuntu?

If you don’t require a fancy GUI, kismet will give you all the software tools of the fanciest (i.e. most expensive) consultants. If you need a fancy GUI, I don’t know what to use. I’m prepared to bet stuff like the one you linked is probably just a GUI wrapper around something like kismet anyway 🙂

Network manager command line interface nmcli

This is an output of command:

* SSID MODE CHAN RATE SIGNAL BARS SECURITY 151022 Infra 4 54 Mbit/s 74 ▂▄▆_ mary Infra 4 54 Mbit/s 74 ▂▄▆_ WPA2 151022 Infra 40 54 Mbit/s 70 ▂▄▆_ mary5 Infra 40 54 Mbit/s 60 ▂▄▆_ WPA2 Don Ceci Infra 6 54 Mbit/s 34 ▂▄__ WPA1 WPA2 epg72 Infra 11 54 Mbit/s 34 ▂▄__ WPA1 WPA2 Mitio Paynera Infra 2 54 Mbit/s 24 ▂___ WPA1 WPA2 Nina Infra 1 54 Mbit/s 17 ▂___ WPA1 WPA2 Filka Infra 10 54 Mbit/s 17 ▂___ WPA1 Mihaylov Infra 11 54 Mbit/s 14 ▂___ WPA1 WPA2 HomeS2000 Infra 6 54 Mbit/s 7 ▂___ WPA1 WPA2 alex1 Infra 7 54 Mbit/s 7 ▂___ WPA1 WPA2 epg72 Infra 11 54 Mbit/s 7 ▂___ WPA1 WPA2 Valia Infra 11 54 Mbit/s 7 ▂___ WPA1 WPA2 Silviq Infra 10 54 Mbit/s 4 ____ WPA2 

nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d | sort -n 

and output will be sorted by channel:

For continues scan you can combine with command «watch»:

watch "nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d | sort -n"

WiFi Analyzers for Linux

WiFi analyzer tools are software tools that enable IT professionals to analyze, manage, survey, scan, and monitor their WiFi networks. WiFi analyzers and WiFi management software provides administrators the ability to collect data, monitor issues and access points, identify problems, and more. Compare the best WiFi Analyzers for Linux currently available using the table below.

Kismet

Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR (software defined radio) hardware like the RTLSDR, and other specialized capture hardware. Kismet works on Linux, OSX, and, to a degree, Windows 10 under the WSL framework. On Linux it works with most Wi-Fi cards, Bluetooth interfaces, and other hardware devices. On OSX it works with the built-in Wi-Fi interfaces, and on Windows 10 it will work with remote captures. There are several ways you can help support Kismet development financially if you’d like to; support is always appreciated but never required. Kismet is, and always will be, open source. With the new Kismet codebase (Kismet-2018-Beta1 and newer), Kismet supports plugins which extend the WebUI functionality via Javascript and browser-side enhancements, as well as the more traditional Kismet plugin architecture of C++ plugins which can extend the server functionality at a low level.

sparrow-wifi

Sparrow-wifi has been built from the ground up to be the next generation 2.4 GHz and 5 GHz Wifi spectral awareness tool. At its most basic it provides a more comprehensive GUI-based replacement for tools like inSSIDer and linssid that runs specifically on linux. In its most comprehensive use cases, sparrow-wifi integrates wifi, software-defined radio (hackrf), advanced bluetooth tools (traditional and Ubertooth), traditional GPS (via gpsd), and drone/rover GPS via mavlink in one solution. Wifi source hunt — Switch from normal to hunt mode to get multiple samples per second and use the telemetry windows to track a wifi source. Bluetooth identification — LE advertisement listening with standard bluetooth, full promiscuous mode in LE and classic bluetooth with Ubertooth.

wavemon

wavemon is a wireless device monitoring application that allows you to watch signal and noise levels, packet statistics, device configuration and network parameters of your wireless network hardware. It should work (though with varying features) with all devices supported by the Linux kernel.

Top 4 Linux WiFi Scanners

If you live in a populated area, you’ll likely be having several WiFi networks in your surrounding, each working on a specific WiFi channel.

This may affect your WiFi’s functionality unless you know which channel has minor traffic or is less congested.

Since WiFi channels with fewer users guarantee a speedy performance to every WiFi network, finding an ideal one may get complicated.

But it’s not impossible. Now you can use multiple WiFi channel checker tools, known as Linux WiFi scanners, to discover all available wireless networks in your area.

This article will tell you the four best Linux wireless scanners that you can use on almost all Linux distributions, such as Ubuntu and Linux Mint, to find the ideal nearby WiFi channel.

So please keep reading and learn everything you need to know about it!

Top 4 Linux Scanners for Wireless Networks

Using a Linux WiFi scanner lets you instantly figure out the optimal channel that comes within your WiFi network’s range.

Let’s take a look at the top 4 Linux WiFi Scanners.

1. LinSSID – Graphical WiFi Networks Scanner

LinSSID is an easy-to-use Linux scanner that can scan both types of networks, 2.4GHz, and 5GHz. Moreover, as it is written in C++ with the help of Linux wireless tools, it provides an ideal performance on all sorts of systems.

What’s more? It has a graphical user interface that quickly detects all nearby WiFi routers and even ad-hoc connections.

You can install LinSSID on your computer using PPA for DEB-based Linux distribution systems, including Linux Mint and Ubuntu.

Follow these steps to install and run LinSSID on your device:

ubuntu$ubuntu:~$ sudo add-apt-repository ppa:wseverin/ppa

ubuntu$ubuntu:~$ sudo apt-get update

ubuntu$ubuntu:~$ sudo apt install linssid -y

• You can launch LinSSID in two ways; as a root or as an ordinary user. Thus, if you want to access it as a normal user, you have first to use visudo to set the SUDO program and then take help from the gksudo system. Type the following command:

ubuntu$ubuntu:~$ sudo visudo

• You will use visudo as root for the configuration of the file ‘/etc/sudoers.’ Next, you have to add the “user ALL=/usr/bin/linssid” command line at the end of the file to get LinSSID’s root access.
• Finally, launch LinSSID by typing the command line:

gksudo linssid

On the other hand, you can also run the program directly from the menu. Once it’s launched, it will ask you for the password. Then, all you have to do is select the channel or interface you want to connect your WiFi connection with.

LinSSID’s graphical user interface will give you information about many things, like:

• SSID
• WiFi Channel
• Noise levels
• Signal Strength
• MAC Address
• Speed, etc

2. nmcli – A NetworkManager Controlling Tool

Network Management Command-Line Interface (nmcli) helps Linux distributions (with a graphical interface) control NetworkManager effectively.

Although nmcli doesn’t come with a graphical user interface, like every other Linux WiFi tool, you can easily use it to scan all the available WiFi networks within your computer’s range.

The key to using nmcli like a pro is knowing all the commands properly.

Once you install nmcli correctly on your device, you can get a list of available WiFi networks by typing this command:

nmcli dev wifi

If nmcli doesn’t work this way, you can use “sudo” to obtain the list with even more information about each wireless network. Enter this command:

nmcli -f ALL dev wifi

Besides, you can use nmcli for all standard Linux distributions with GNOME graphical user interface, including Ubuntu, Linux Mint, and others.

3. Wavemon – A ncurses-based Tool for Wireless Network Devices

Another tool that you can use to scan WiFi networks is Wavemon. Unfortunately, like nmcli, it doesn’t have a graphical user interface.

However, the good thing about this WiFi scanner is that it doesn’t ask you for a series of command lines for the installation process. That’s because this user-friendly ncurses-based tool has a Text User Interface (TUI) that lists down all the options on the main screen.

If you want to use Wavemon on Ubuntu, enter this command in the terminal to install it:

sudo apt install wavemon

Yes, you can use the application on other Linux distributions as well.

4. NetSpot – The Best WiFi Analyzer Tool

If your luck doesn’t work out with the Linux mentioned above WiFi scanners, you can download NetSpot on your computer. It is, so far, the most straightforward WiFi analysis tool that operates on both macOS and Windows.

It performs several wireless website surveys, analyses, and troubleshooting on your device.

Fortunately, the application comes for free, so you can give it a try if nothing works out for you.

The Bottom Line

Having the fastest internet connection without any interruption is like a dream come true. Fortunately, now you can turn it into a reality by installing the best Linux WiFi scanner on your computer.

All you have to do is copy and paste the command lines in the right places, install the scanners, and find the perfect WiFi channel for your network.

However, if you’re not good with tech-related things, you can opt for Wavemon and do all the scanning with fewer command lines!
