Is there a tool like wifi analyzer for ubuntu?

Question

Wifi analyzer Is a thorough application on android for managing WAP, wifi strength signal etc. I was wondering if there was a similar tool 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 :-) — , Jan 08 '13 at 18:00

Network manager command line interface nmcli

nmcli d wifi

This is an output of command:

*  SSID           MODE   CHAN  RATE       SIGNAL  BARS  SECURITY

But you can use:

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

and output will be sorted by channel:

CHAN  BARS  SIGNAL  SSID

For continues scan you can combine with command "watch":

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

@Anwar Yes, it is a wifi analyzer in that it can show you all wireless signals, their strength, channel, and security. It appears to be part of the NetworkManager package, so most distributions probably have it already! — Johann, Dec 28 '16 at 18:59
You can save defining the columns by hand use nmcli d wifi | ( head -n1; sort -k1.44 -n ) to sort by channel where 44 is the 44th character column which is the channel column at my system. The head command keeps the header row on the top. — Daniel Böhmer, Jan 25 '19 at 01:06
I use nmcli -f "CHAN" d wifi | tail +2 | sort | uniq -c | sort - first column is number of occurrences, second column - channel — Ilya Bystrov, Feb 20 '20 at 02:16
My output of the command is: IN-USE SSID MODE CHAN RATE SIGNAL BARS SECURITY — Quidam, Jun 03 '20 at 16:30

You could use Wavemon. It's available in the Software Center, (or via apt, sudo apt-get install wavemon).

Screenshot of Wavemon

Screenshot from Wavemon's Github (GPLv3).

Once you have installed wavemon, open a terminal (CTRL+ALT+T) and type wavemon.

I like wavemon more than kismet for most quick purposes due to no extra groups and stuff. – dhaupin Sep 22 '15 at 23:21
Any idea how they pull that data out of the device. Mine shows a signal to noise ratio I can't see anywhere else – GuySoft Jun 16 '22 at 10:00

You could use linssid which offers a nice easy to use GUI for both the 2.4 GHz and 5 GHz channels. http://ubuntuhandbook.org/index.php/2013/08/linssid-wifi-scanner-for-ubuntu-linux-mint/

To install linssid in Ubuntu 16.04 and later type:

sudo apt install linssid

You may need to run it from the terminal as sudo linssid despite being able to install it from the software center. (clicking the icon may just do nothing) – jocull Sep 18 '18 at 17:43
yes, clicking the icon does nothing ~ – monkut Apr 14 '20 at 00:55
Using icon has worked for me over the years and most recently also on Ubuntu 20.04 LTS. Installed it using the command line – Hannes May 02 '20 at 01:54

Agreeing with Hannes- The icon in GNOME launcher works for me (20.04, linssid 3.6-4build2 via apt), note that it prompts for a password upon launch in order to function. – Michael Noguera Jul 15 '20 at 16:06

There is one more tool In Ubuntu software Centre named as Kismet.

Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any supported wireless card using the Airo, HostAP, Wlan-NG, and Orinoco (with a kernel patch) drivers.

Can make use of sox and festival to play audio alarms for network events and speak out network summary on discovery. Optionally works with gpsd to map scanning.

you can install it from terminal( CTRL+ALT+T) also with

sudo apt-get install kismet

Kismet is a complex tool, it consists of a scanner daemon element and a client. These can be run on diffrent machines. So a network of Raspberry Pi can scan an area and display on a central machine. Or it can be run on a single machine. It will identify hidden networks as well but only if a client in range connects to them. – Stuart Aug 23 '19 at 14:30
Note that Kismet has its own ppa if you want to get an up-to-date build. Install instructions are here: https://www.kismetwireless.net/docs/readme/packages/#installing-kismet – Michael Noguera Jul 15 '20 at 16:29
